October 2023 Production Updates

Hey everyone, here are the Oct 2023 production updates!

Ok so the marketing team asked me to do this in a video format, so enjoy.

Moving

A few months ago, we signed a lease on a new building a few minutes up the road on 120 Randall Drive. This space is not just double in square footage (around 8000sqft to 15,000sqft), we also get double high, 20ft ceilings, which will allow us to store a ton more materials as well as open up the possibility for new development space to help us build new products.

We now have full access to the building, and are starting some construction to outfit the space and get things moved over. Look out for an invite for housewarming in the next few months!

LongMill MK2 and Extension Kits

Production for LongMills and Extension Kits continues to move along smoothly. Shipments for these orders are generally shipping same day or within a few days.

We’ve recently made a small change to the laser-cutting process for the steel plates by switching to nitrogen from oxygen, which has shown to improve the quality of the cut edges on our parts. We expect the quality of the coatings and threading on tapped holes to improve because nitrogen reduces the impurities found on the edges of cut parts.

First batch of nitrogen cut parts

We don’t see a huge difference at this stage between the two different processes, but as we continue to work our way in processing all of the parts, we’ll be able to compare our QA reports to see if there is an improvement.

We’re also working on reducing our reliance on the 3D printing farm by experimenting with injection-molded feet. At the scale we are printing now, we believe that the cost of injection molding will save us money in just a few months.

Sample of injection molded feet

We did run into a small issue where the manufacturer applied the finishing for inside the part rather than on the outside. As you can see in the photo, the outside of the foot is shiny, rather than a matt finish. The manufacturer is currently working on refinishing the molds so that they will look in our opinion, better for the next batch of samples.

In other news, we are also working on improving the quality of our lead screws. In the previous batch, we ran into a lot of issues of bent screws, so we started looking for some alternative suppliers.

Mike checking in the screws under a microscope

This lead us down a pretty deep rabbit hole because we found that there are a lot of different types of threads and standards, some of which are country dependant. At this stage, we’re focusing on making the screws backwards compatible so that they are functionally the same as before.

Additionally, we believe that we can make the finish of the screws smoother, which may also lead to smoother motion and less wear and friction on the nut.

LaserBeam

LaserBeam orders are shipping out consistently and we have stock ready to ship. We are currently restocking some of our parts over the next few weeks.

Vortex Rotary Axis

We have now cleared the queue for the Vortex Rotary Axis for the pre-orders. We now have them in stock and can ship them within a few days. We only have around 70-80 units left, so make sure to grab one before we run out!

Production for the new batch is now underway, and we expect Batch 2 of the Vortex to be ready in about 3 months.

Sienci Router

Thank you for everyone for participating in our survey. If you haven’t participated and would like to, please check out the Sienci Router Survey which will help us learn more about what our users are looking for in a new router.

For the uninitiated, we’ve recently embarked on a new project exploring the possibility of building our own router or spindle system. Here are some reasons:

  • The Makita RT0701 which is the most popular router used in hobby CNC machines have gone up in price, and may continue to increase in price.
  • More people are reporting issues with the Makita RT0701, such as the bearings overheating, button breaking, and the speed dial losing its tension.
  • There are no inputs to allow PWM speed control, unless you use a VFD and spindle combination
  • Routers are loud

Our goal is to:

  • Provide an alternative to the Makita RT0701 of a similar form factor so that it can be easily installed in place of it.
  • Incorporate controls that allow on/off and speed control using gSender or in gcode directly, same as a spindle
  • Improve the longevity and reduce noise
  • Improve efficiency, power, and allow for a wide variety of bit sizes to be used

Additionally, we may incorporate features such as:

  • Grounding through the bit, so that touch plates and bit setters can be used without needing to attach a probe to the bit or collet.
  • Easier mechanism to change bits

There were a couple interesting things we found in the survey:

  • While we assumed people would comment that they wanted more power from the Makita, we found that most people were satisfied with the power that it already provided
  • We also assumed people would be more interested in using 1/2″ tooling, but it appeared it was not a feature a lot of people didn’t find useful
  • Another very popular request that we didn’t include in the survey initially was an easier way to change tools, such as an auto tool changer.
  • The majority of respondents told us that they would budget between $300 to $500 for a new router or spindle system, which is higher than we expected.

At this current time, we are in progress of researching some different motor options, as well as exploring different motor control options to validate that the basic functionality of the router can be produced. Once that is complete, we will be working on developing the mechanics and structure of the router. There is no set timeline yet, but I expect that we’ll likely have something ready to share by the end of the year.

Some interesting things we found:

First is a comparison of running the Makita without a fan, which means basically ripping out the one in there already. We found that there is a decent change in volume at higher speeds. In practice, it sounds quieter as well because the frequencies coming from the fan is more perceptible (lower pitched) than the other parts of the motor.

Johann also mentioned that he found NSK bearings in some routers and CW in some of the new Makitas we were taking apart. The hypothesis is that during the pandemic, there may have been supply chain issues with getting NSK, so Makita used CW in production instead, which coincides with a larger number of bearing failures or overheating issues that we’ve seen happen in the past year.

SuperLongBoard

SuperLongBoard beta testing continues.

We recently received the newest version of the prototypes, which we expect to be put into production after validation. We now have 25 boards we are working with to complete phase 2 of beta testing.

Prototype V2

Here’s a video of us testing the macro buttons, which allow the user to program a specific code or function into the buttons themselves, rather than just start, pause, and stop, which is hardwired into the current control board. In this case, it’s being used to move the machine to a specific position to assist with getting the machine out of the way for changing tools and materials.

We have received the version 2 of the SLB early last week and have been doing our internal testing before we prepare them for use. Here’s a bit of an update (this is the email I sent to the beta testers earlier).

– V2 has a couple of components that had issues and we are manually replacing parts and updating the design. This is minor surgery but a bit tedious working with small parts. We were hoping to start sending out the V2 version at the end of last week, but we are shooting for end of this week and the start of next to have the first 3 boards ready.

– The development team are working on testing and implementing features, listed in the attachment below. This is an excerpt from the main development notes we have. Thought I would share so you guys know what to look forward to them. Some have already been implemented but not tested.

– We also have a newly designed case that we are 3D printing and assembling, which allow you to install the case to the rail of the machine, or on the table or in another place. We are starting production of it now, which will be made from aluminum and acrylic. We should be getting them in Nov-Dec.

Chargeback/Fraud Instance

We recently ran into an issue with someone having placed a few orders for LongMills on our site using different aliases and charging the orders back after they had shipped. It appears to be done using stolen credit cards, but we are looking into this further.

Although this happens very rarely, it is a part of business that we can’t avoid. I just wanted to mention this to warn people to be cautious if they run across any LongMills for sale, still in the box, that seems suspicious, especially in the Montreal area…

September 2023 Production Updates

Hi everyone. It’s September, and we’re going into my favorite time of the year, the autumn. We have quite a few updates for this month.

Want to get news like this directly in your email inbox? Make sure to sign up for our mailing list.

LongMill and Extension Kit Orders

Production for LongMill and Extension Kit orders have continued to move smoothly. We have very short lead times at the moment and most orders should ship within a few days, if not on the same business day.

We have received the controllers that we were waiting on last month and we expect them to last until the end of the year. Other parts are in stock and we hope to have shorter lead times over the next few months.

We also recently launched the Beginners Kit, which was designed to help package everything we believe someone getting started with CNCing should get. The idea was to be able to:

1) Package everything so that it offers a one-stop package for CNCing

2) Allow us to pre-pack a number of kits and ship them out within the same day or next day

3) Improve our efficiency in packing and shipping kits

This is an experiment to some extent for us, since our production team wanted to see if we can streamline our process. As a way to pass along some of the savings, we have been offering $100 for each kit as an incentive.

Interestingly enough, at this moment, we still have about a 50/50 split on Beginners Kit orders and regular machine orders. We’ll continue to see if we see any new trends here.

LaserBeam Orders

LaserBeam orders continue to move out slowly, and most are shipping within a few days.

Vortex Rotary Orders

We have continued to ship around 40 to 50 units per week and are expecting to complete the queue in the next 2 weeks. We are advising customers that the wait time is expected to be around 3-4 weeks, but I expect that after a couple of weeks, we expect the lead times to reduce.

We are nearing the end of the first batch of the Vortex Rotary Axis, with around 100 units left in stock at the time of writing. We are currently working on wrapping up this batch and have started manufacturing parts for the next batch.

We have started to see people using the Vortex in the wild! We are thrilled to see these new results.

Test piece from Colby Browing (Facebook)

Additionally, the gSender team has continued to improve the experience of using the Rotary mode on gSender. We are expecting a new version of Edge to come out in the next week or so. You should continue to see new resources and projects available for the Vortex on our Resources, and we are currently working putting out a few project videos and tutorials on Youtube soon, so make sure to subscribe to stay on top of that!

T8 Spring Loaded Anti-Backlash Nuts

Another recent launch was our T8 Spring Loaded Anti-Backlash Nuts. We saw a common issue with the LongMill was getting the correct tension on the original nuts, and some beginner users were making the mistake for overtightening their nuts and causing them to bind.

The idea for spring loading them was to make them self-adjusting, so that the user doesn’t need to touch them after they are installed. You can read the full article for more information.

We have continued to test our production nuts, which have overall worked well. However, we have noticed that to improve their long-term ability to reduce backlash, we can increase the force holding the arms together to further reduce backlash and allow for more variability of wear over time.

Currently, we are working on some new ideas using spring steel clips and circlips, as the size constraints of the nut create some limitations on the size and shape of the nut we can make.

Additionally, we’ve gotten a lot of feedback where people are also interested in a T12 version, and we are currently working on a design for this as well.

In the next few weeks, we’ll be sending our surveys to our users to gather feedback.

SuperLongBoard Beta Testing

We have installed two SLBs with beta testers last week. One with Ian, who has a Onefinity, and Ed, who has a MK2 LongMill. The objective for the beta testing is to look for issues that we might have missed in the use or design, do real-life comparisons between the old and new board, and do real-life durability and performance testing.

We had really great results with testing on Ian’s Onefinity, which was our first installation. His former setup used the original LongBoard. Once we installed the new controller we noticed a couple of new improvements.

  • – We were able to increase the max feedrate from around 8000mm/min to 16,000mm/min
  • – The noise and hissing on the motors were significantly reduced

There are currently two issues that we are expecting to resolve in the second version of the prototype expected to arrive in the next 1-2 weeks.

  • – Wiring is not good for the homing switches, causing them to disconnect. The new plugs on the new version should eliminate this
  • – Powering on the 24V side before the computer signal can cause an error with the way that the MCU communicates with the drivers. We are expecting this issue to be resolved in the new board as well.

Since this is our first-hand experience with working with our electronics on a different machine, we’re excited about the possibility of offering the SLB on other hobby CNC machines.

For Ed’s testing, we also noted these improvements:

  • – The responsiveness and sensitivity of the touch probe has improved, which we believe is because the processing speed of the MCU is much faster, and so it takes less time for the touch to be detected.
  • – While inconclusive if this makes a difference, but we noticed that the inductive sensors with the original board were flickering at times, whereas the new controller showed the lights to be on bright. We suspect that because the power coming to activate those sensors are coming from the power supply instead of the computer, we should expect the reliability of the homing switches to improve. We tested the homing sequence and they both work
  • – We were able to increase the feedrate from 4000mm/min to 6000mm/min
  • – We were told that on the original board, turning on the vacuum and running the board on the same circuit would cause a disconnection. We tested the new board while sharing a circuit, and found that it did not have a disconnect.

We are also working through an issue where a skew in the y-axis causes binding at rapids (about 4mm of skew). We think that this may be caused by a few things:

  • – The skew itself causes more stress on the machine, so the motors are over-torqued.
  • – Since Ed is using the old version of the power supply which is rated for 10A, rather than 12.5A, the board needs more power.

Based on the motor tuning done by Andrew and his team, we are running the motors at around 3.5A peak, which is about 20-30% higher than the default setting on the TB6600 on the original boards. This means that if all motors draw power at peak simultaneously, the board could be drawing around 14A.

We have replaced Ed’s power supply with a higher-powered one and are continuing the testing.

After the testing, we found several different things that we can improve on, and Chris and the rest of the technical development team are making changes and updates to the gSender and firmware to add more features and improve the performance and settings on the board.

Newest version of the SLB

Assuming all goes well, we hope to have the new boards available near the end of the year.

Hamilton Woodworking Show

After a long hiatus due to COVID, we are coming back to the Hamilton Woodworking Show! Make sure to come join us, where we’ll be showcasing the LongMill, LaserBeam, and the Vortex! The event is on Oct 20 to the 22nd.

We’ll also have a few Beginners Kits available for sale so you can come check out our stuff and go home with a machine.

Sienci Router

Another new project we’ve started working on is our own router/spindle! The idea is to build something to replace the very common Makita RT0701 router with something similarly compatible. Although the Makita RT0701 is a very good option, we felt like there were a couple of areas that we could improve such as:

  • – Control over the speed with connecting with gSender
  • – Durability
  • – Precision
  • – Noise

We’re still in the early stages of development, so we’re still trying to decide on what sort of features and functionality we want to see in this new product.

We don’t have a specific timeline yet for this product, but we aim to have something available at the start of next year.

Want to provide us with feedback on what you want to see in our development? Please fill out the survey below, or use the link (https://forms.gle/LwLu7ydBKBnNcmDt5)!

Introducing LongMill MK2 Beginners Kit

The LongMill MK2 Beginner’s Kit is a, “everything you need to get started with CNCing” package. This package comes with the LongMill MK2 CNC machine and basic accessories that the large majority of users order. Not only does this help new users get everything they need to start, but also reduces lead times as it allows us to make pre-assembled kits in stock.

What is the LongMill MK2 Beginners Kit?

We created the LongMill Beginner’s Kit based on sales data for items that customers buy with their LongMill, as well as feedback from our customer service team on items we felt were most beneficial for customers to have when opening their boxes.

The Beginner Kit comes fully loaded with:

1 x LongMill Benchtop CNC MK2 – choose between 30×30 or 48×30

1 x AutoZero Touch Plate

1 x Starter End Mill Set

1 x LongMill MK2 Magnetic Dust Shoe

1 x Makita RT0701C Router

It should be noted that all of the items can be purchased separately, customers who wish to pick and choose what they get with their order can still do so through our Store.

It’s also important for us to mention that there are also certain items that we feel like although a lot of people buy them, they are either not needed for beginners or don’t bring a lot of value.

For example, let’s take the MK2 Lead Screw Dust Shield. For regular use, they are not needed at all. Since the lead screws and nuts on the LongMill are designed to be used in dusty environments, they do not need to be covered. In fact, they can be inconvenient in ways as they need to be removed every time the nuts have to be adjusted.

The other big omission folks might notice is the Inductive Sensor Kit for the LongMill MK2. This is because we believe that most beginners will find them unnecessary, and due to the complexity of setting them up, we find a lot of customers have issues due to improper setup and settings. Additionally, since crashing the LongMill won’t damage the machine, using limit sensors are not needed for limiting travel. All in all, we feel that for most people, they will be more trouble than they are worth. We recommend adding them once customers are familiar with using their machine and are ready to take the next step in doing more advanced work.

You might also have noticed that the 1/8″ Precision Collet for the Makita RT0701 also isn’t included in the list. That’s because the Starter End Mill Set comes with a 1/4″ to 1/8″ Collet Adapter included.

The items in the Beginner’s Package are there because we think they are the products we think you should get to have the best experience as a beginner. We don’t want to sell you stuff you probably won’t need, especially when starting out. However, if you want those items, feel free to add them to your cart, we won’t stop you!

Why does the Beginners Kit exist?

We decided to create the Beginners Kit as we believe it will streamline many of the processes at Sienci Labs and in the ordering for the customer.

One major thing we’re trying to work on, especially in the busy times of the year is keeping up with demand. Most customers will have experienced some sort of wait time for their machines. We’ve identified that if we can build the same group of kits with the same items over and over again, rather than customizing the kit for every customer, we can save a lot of time and money. 

We also found that customers were getting confused with what to order with their machines when first starting out, which meant that in some cases, they would need to make more than one order to get everything they want. In fact, one of the most common questions we get is, “What do I need to get with our machine?”

Additionally, by pre-packing machines, we can stockpile them during slow seasons and ship kits more quickly. This helps keep our packing team busy, better prepared for shifts in sales during the season, and allows us to ship machines significantly faster than before. And at some point, if this works really well, we can also start setting up distribution in the US and other parts of the world with pre-kitted machines so that we can save on shipping costs overall as well.

Another part of this move is also with regards to managing customs, as we found with certain orders with a lot of line items in the customs documentation were prone to being held up and there being more issues overall. We believe that by streamlining the machine kit into fewer line items, we can help clear customs more easily. 

Also, now that the pandemic is basically over, we’ve been getting a lot more people coming in directly to the shop to purchase machines and we’re planning on going to some shows and events, and we’ll be able to take some machines to sell directly!

So rather than having things set up so that customers have to pick and choose every single item, we bundle everything they need to get set up with their machine based on what the average person orders with their machine.

How does the Beginners Kit work?

Interested in ordering a LongMill MK2 Beginners Kit? Here’s what you can do!

  • Choose the version of the LongMill MK2 Beginners Kit you want and put it in your cart
  • If you want to order anything else at the same time, feel free to include it in your order.
    • IMPORTANT: Your order may ship together or in two separate packages. You will receive tracking info once your order ships and either one or two tracking numbers.
  • You should have your shipped out within the next business day. Most transit times when with courier within North America is 3-5 days, but could take up to 2 weeks.

Beginners Kit Discount

We are currently offering roughly a $100CAD discount on Beginners Kits.

Here’s why:

  • We are moving in October and we want to clear out as much inventory as possible
  • Since we’re expecting some cost savings in streamlining the packing and shipping process, we are passing along these savings to you!
  • This is also an experiment to see if the Beginners Kit will be a potential staple product for us in the long run.

This offer will be available until:

  • We run low in stock
  • We can’t keep up with the sales
  • We realize the beginners kit wasn’t a great idea after all…

But otherwise……………..

Everything you need to know about the spring-loaded anti-backlash nut

Hi everyone, I’m excited to share a small development, the Spring Loaded Anti-Backlash Nut! As we’ve continued to have LongMills out in the wild, we’ve recognized that the finickiness of the Delrin Anti-Backlash Nut was a pain point for our users, such as the need for adjustment on a regular basis, the potential for the adjustment screw to fall out, and improper tensioning causing jamming, especially at higher speeds.

The Spring Loaded Anti-Backlash Nut is designed to address these issues by using a set of springs to tension the nut against the threads radially, allowing smoother operation and no adjustment needed from the operator. We are now putting this out into the wild for field testing!

These nuts are drop-in replacements for any T8 size Delrin nut on the MK1 or MK2 LongMill.

Assembled Spring Loaded Nut

This new version is now available on sale and ready to ship in our store.

Flaws with the current Delrin Anti-Backlash Nut

For those who don’t know, the Delrin Anti-Backlash Nut design comes from the original Openbuilds Anti-Backlash Nut Block. At the time, this was more or less the best option for this type of hobby CNCing for T8 lead screws because it’s:

  • Inexpensive
  • Simple
  • Easy to manufacture
  • Easy to integrate
  • Low maintenance
  • Generally works pretty well

Since we were still in the early stages and didn’t have the manufacturing volume and capability to make our own designs at scale, we stuck to a lot of open-source and off-the-shelf components. As some users may have noticed, we’ve slowly been working on different innovations to improve and redevelop our own components to work better and more reliably.

The original design comes with a couple of flaws:

  • Requires constant adjustment to reduce backlash
  • Over-adjustment or incorrect assembly results in binding
  • Inconsistent resistance during its life cycle

To improve on this design, I worked on some different concepts using springs to pre-load the nuts, finally resulting in this shape:

“This design incorporates OpenBuilds, LLC design work(s) shared Open Source under the CC BY-SA 4.0 License.”  

In this design, we use two springs in the gaps to apply radial preload on the lead screw threads. This allows the two “arms” to push into the threads as it wears, automatically reducing the backlash.

According to Helix Linear, another manufacturer for anti-backlash nuts, “the radial anti-backlash nut can handle loads greater than the spring force. There is also less of an increase in required drive torque compared to an axial anti-backlash nut.”

In this design, we use two arms instead of three typically used in industrial nuts, to keep the same form factor, so that the new nut can drop in to replace the current version with no modification.

Other benefits include:

  • Zero adjustments or maintenance after installation
  • Lower potential for binding
  • Smoother, lower resistance operation

Next steps

We’ve done some initial testing with 3D-printed nylon nuts, which have pretty good results, showing basically no backlash over testing. We’ve now ordered 400pcs (100 sets) of machined Delrin nuts. Our goal is to put them available for sale for people to use on their own machines. If they work well in the field we will switch to spring-loaded nuts as the default standard in LongMill kits.

I should include a disclaimer, which is that these are still a new, unproven product, and it is still possible that in the long term they may perform worse than the original nut.

We want to put these nuts out in the field so that we can get feedback and long-term testing done to validate the design. I’m very confident that this will make an improvement to the overall experience of using the LongMill, but before we make the switch, we want to make sure that we do some real-life testing.

There may be some small tweaks we may consider making, such as adjusting the spring force and length and spacing of the arms, which may happen based on the beta testing.

For this first batch of nuts, we will collect some survey data to help understand the experience of the user. At this current stage, we only have T8-size nuts, but we may expand it to the T12 size as well.

Everything you need to get to for starting CNCing with your LongMill

One of the most common questions we get from folks looking to order a LongMill is “What should I get with it?”. This article and video are designed to help you walk through everything you need.

The average order value for customers first purchasing a LongMill and accessories in the past 12 months is approximately $2850CAD or $2190USD, which means that for most customers, you can easily get a complete setup for under $3000. These numbers represent the total value of the order, which includes the machine, as well as most other accessories such as the software, router, endmills, a dust shoe, touch plate, and other items. You should allocate a few hundred dollars for other items that you may or may not have in your shop already, such as a bench, computer, and vacuum.

Here is the breakdown of the most popular items that customers order along with their LongMill by percentage.

The LongMill

If it’s your first time getting into hobby CNC, you might be a little intimidated by what you need to get started. This video is designed to cover everything you need to have in your shop.

Your first, and largest purchase is going to be the machine itself. The LongMill Benchtop CNC is a capable option for hobbyists who are looking for a lot of functionality found on more expensive machines but in a more budget-friendly package. Depending on the size, you can get a LongMill for around $1800 to $2300CAD or around $1400USD to $2000USD, which makes it one of the least expensive options for the size.

While there are cheaper and more expensive machine options out there, we believe our specific machine is best suited for customers who:

  • Are looking to do this as a hobby, with some interest in production and business work
  • Need high-quality resources and support
  • Willing to make a small compromise in cutting speed but still be able to produce the same type of work as more expensive machines

Our main goal as a company is to make CNC accessible to everyone. This comes down to a number of commitments to our customers and products:

  • To make products that are affordable for the average hobbyist
  • Provide resources, support, and instructions so that we can make sure our customers can be successful in using our products.

We feel that customers not only choose the LongMill because it is an affordable option, but because we created a helpful and supportive community around our products.

If you’re not sure what size to choose, we recommend considering the working areas of each version of the machine, and determining what size fits in your shop as well as can do the type of projects that you’re interested in doing.

Router or Spindle

The base LongMill kit does not come with a router, since we wanted to let customers choose which router they want to use with their machine. The LongMill can work with several different palm routers, but the one that is the most popular and the one we recommend is the Makita RT0701, as it’s inexpensive, readily available, and has more than enough power for general woodworking use. You can order this directly through us, or at most local hardware stores.

The LongMill also can be retrofitted with an aftermarket spindle, and we provide 71 and 80mm router mounts for larger spindles, however, due to cost and complexity, we only recommend this upgrade to experienced customers. More information about routers and spindles can be found in our resources.

End Mills and Bits

You’ll also need to get some end mills and bits to start off your CNCing journey.

Assuming you have a Makita router, you’ll mostly be using ¼” shank tools, or if you get either the ¼” to ⅛” adapter, or the ⅛” Precision Collet, ⅛” shank tooling as well.

We provide dozens of different bit options and packs on our store. If you’re not sure what to get, we recommend checking out one of the End Mill Sets, such as the Signmakers Set and Machinist Set.

If you’re starting out for the first time, I recommend the Starter End Mill Set, which comes with all of the bits that we think you’ll need and a collet adapter. The Starter End Mill set, which we recommend for first-time users, is about $45USD or $60CAD, and come with 9 different bits and accessories.

Prices for bits vary a lot, especially when you get into high-end tools, but for the average user, you should expect to pay a few dollars for smaller tooling, and up to around 20 dollars for a larger bit.

Bench

The last thing you must get for your CNC is a bench and spoiboard. This is just a large surface you can put your machine on. It should be noted that the surface should be as flat and strong as possible, since any flex or irregularity may show up in your cuts as well. Some people will make a bench from scratch, which can cost $100s of dollars, but even an old sturdy desk or dining room table can work as well.

Some different ideas and inspirations can be found in our resources.

You’ll also need a spoil board or wasteboard, which acts as a consumable surface for your projects to sit on. We recommend ¾” MDF, as its cheap, readily available, and dimensionally stable. You should be able to buy a 4×8 sheet and cut it into 2-3 wasteboards for about $60.

Computer and Software

There are two main pieces of software you’ll need with your CNC machine. First is the gcode sender. We build gSender as a feature-filled, powerful sender specifically for the LongMill. This program lets you send jobs, change settings, control your machine, and integrate with accessories like the touch plate and inductive sensors. Best of all, it’s completely free!

There are other gcode sending software, such as UGS and Openbuilds Control, but we think you should use gSender.

I recommend checking out our resources where we talk about different CNC software (Broll of scrolling through the resources, https://resources.sienci.com/view/lmk2-choosing-software/ or checking out our video on software to help you choose which software to get.

If you want to read about our thoughts on Free vs Paid software, we recommend reading our article on the topic.

Dust Collection

CNCing can be really messy, which makes dust collection an important part of your setup. 

At our shop, we use a Rigid Shop Vac and Dust Deputy, both of which can be purchased for about $200. This sort of set up will be more than capable for hobby CNC dust collection use.

To help clean up dust while cutting, we have the Dust Shoe, a $60USD, $75CAD attachment which goes on the front of the machine to suck up dust while your job is cutting. This particular one works with the 2.5in hose from the Rigid Vac perfectly.

Work Holding

To keep parts from flying out while cutting, you’ll need some form of work holding. Certain methods, such as using screws or hot glue, are very inexpensive and are easy to use. 

Some users will set up a t-track table on their wasteboard which allows you to use t-clamps and ¼” bolts to have a fast and adjustable system for workholding. A full set costs about $100USD or $125CAD.

I should note what makes our t-tracks unique is that they use ¼”-20 bolts rather than t-bolts which are harder to find, so that you can buy different size bolts from the hardware store if you want to make your own t-clamps.

There are a lot of workholding options, so I recommend checking out our resources page for different options.

Touch Plate and Inductive Sensors

When starting your job, the LongMill needs to have a set origin point. You must choose a starting point for the machine to start from, and it will perform the movements sent by the computer from that point, in relation to the starting point.

The important thing is to setting the starting point. You can choose the starting point manually by just jogging the machine to the place you want to start and “Zeroing” the machine, but we’ve created the touch plate to help semi-automate the process.

We currently have a simple touch plate for around $30, and a more advanced AutoZero touch plate for around $100. 

Additionally, you can add limit or homing switches to your machine. These are sensors that are set up at specific corners of your machine so that you can return the machine to a specific position over and over again (Broll of homing). For the LongMill, when you shut off your machine, it does not remember the specific position relative to itself, and so by having a specific homing position to return to, you can use this to reference the positions of the machine automatically. For example, if you want to set up a job in the same position over and over again, you can home your machine and find the origin of the part relative to the home position after you’ve shut your machine off.

You can get an inductive sensor kit for about $50-60 dollars from our store, however, we generally recommend this to only advanced users, since the setup and process for using it can be complicated, and we generally recommend users who are already familiar with their CNC machines to use it.

Other Accessories

The LongMill also is compatible with other accessories, like the Vortex Rotary Axis and LaserBeam add-ons that provide additional functionality. Over the past few years, we’ve developed these add-ons to plug and play with the LongMill. We plan, over time, to continue to create new add-ons and accessories that help our customers do more things.

For a full list of other add-ons and accessories you can get with your LongMill make sure to check out our add-ons section in our store (https://sienci-upgrade3.cospark.io/product-category/addons/mk2-addons/).

Maintenance Items

The LongMill requires some regular maintenance which is easy and straightforward to do. Recommended maintenance checks can be found in our resources.

There are only two consumable items, the Delrin Ant Backlash Blocks and Delrin V-Wheels which we recommend replacing every 1500-2000 hours, roughly once a year of regular use. Some customers choose to have them on hand just in case.

Conclusion

I hope this helps answer the “what should I get with my LongMill” question we get all of the time. If you have any other questions, please feel free to reach out!

August 2023 Production Updates

July was a bit of a slow month due to the Vancover port strike holding up shipments for us to ship LongMills in the queue. However, now that parts are back to arriving again, we’re picking back up with our regular routine.

We have a lot of news to cover, especially with the pending release and shipping of the Vortex Rotary axis and new development around the SuperLongBoard.

UPS reaches labour deal with Teamsters before strike

This July, we found out that Teamsters working for UPS were preparing for a strike in August, which would have disrupted shipments going to the US. However, UPS and Teamsters have settled on a new UPS contract which increases worker wages across the board and improved working conditions.

We are happy to hear that a resolution has been made, especially as we get into the busiest part of the season for our business.

LongMill and Extension Kit Orders

July has been a slow month for us shipping out LongMills as we have been affected by the port strike that delayed our shipment of controller boards. However, I’m happy to announce that we will receive the boards today and expect to clear the queue in the next 2 weeks.

The large majority of the pending 100 LongMill orders have been packed and are waiting to have the controller boxes done to have them shipped out.

Some LongMills waiting to be shipped

As some folks may know, we’ve continued to work on smoothing out the process of dealing with customs for shipments going to the US. Recently, we’ve been assigned a single contact with UPS to handle all of our LongMill shipments that need customs clearance going to the US. We found that some items were being miscategorized for duties and taxes, and we suspect it is because a big part of this is a manual process that causes human error. We believe that having a single contact who is familiar with the line items will speed up the clearance process with fewer mistakes.

A few new design updates on the LongMill MK2 design include a focus on phasing out of using M3 bolts in the assembly process and replacing them with M5 screws, including parts such as the couplers and ACME locking nuts. We are phasing out components using M3 screws in the LongMill assembly process because they are prone to stripping the heads more easily. Eventually, a full LongMill will be able to be assembled with just one M5 Allen key and our special wrench that we provide (as well as a drill and bit to mount your LongMill to a wasteboard of course).

We are also starting to use longer Z motor cables for the motors so that LongMill 48×30 kits, which are now the most popular variant, will not need a motor extension cable, simplifying the assembly process as well.

Additionally, now that the design of the LongMill MK2 has matured over the past year or so since its launch, we are moving to figure out injection molding parts for it for the first time. If you didn’t know, we 3D print several components for the LongMill MK2, including the dust shoe and feet. We found that due to the large number of feet we print, moving to injection molding would be a natural next step to reduce our need to rely on the 3D print farm, which is harder to scale production for.

We are entering into the first day of August with around 100 pending LongMill orders, but we expect to clear the queue in a week or two, after which we expect to shorten lead times again.

Vortex Rotary Axis

The last of the Vortex Rotary Axis parts have arrived at the end of July and we are now starting production and assembly!

Our team has been continuing to work on different areas of the Vortex so that when they get into the hands of our users, they’ll have everything they need to get started. This includes:

  • Thorough assembly and installation instructions. We just completed initial trials and tests of the assembly process to make sure that we provide clear instructions to make it easy to put together. We found that everything came together really easily, except for the cam clamping system for the t-track, which we are currently working on to make it less finicky. We estimate that most users should be able to put it together in about 30 minutes. Full instructions will be found on our Vortex Resources soon.
  • Video content about the Vortex. We understand that not a lot of how-to and tutorial content exists for rotary CNCing. Our video production team and the engineers are working on the next steps for creating content so that our users can learn how the Vortex works and how to use it.
  • The gSender team continues to work on completing Rotary Axis implementation into the gSender, including homing and visualization for rotary. These features will be in gSender Edge at the time of launch and will be merged into the main version of gSender down the line. You try and learn about the latest version of Edge here.

We will start to trickle out Vortex Rotary Axis kits over the next week or two as we iron out the last bits of details. We expect the first batch of kits to start shipping out at the end of this week or early next week.

LaserBeam

LaserBeam production continues to move along smoothly, with most orders shipping out within a few days. We have stock available for the LaserBeam ready to ship now.

SuperLongBoard

Work for the SuperLongBoard (SLB) continues on. The team has been able to successfully test the main functionality with excellent results. However, we found our initial tests with the onboard compute module to be unsuccessful, as the Broadcom and Rockwell-based processors used on smaller compute modules to not be powerful enough to accommodate the visualization of g-code directly onboard.

Revised SLB

While additional software development was able to make significant speed improvements, we felt that the compute module would most likely need more headroom in the future if we were to implement other features down the line such as having a camera monitoring system, which we felt would be difficult to add due to a limitation of system resources.

We have now started looking at higher power compute modules, single board computers, and other hardware that we feel would ensure that the onboard gSender experience would be smooth and seamless, as well as provide headroom for future applications. However, the downside is that higher-power computers also cost more, and while our initial budget was around $80CAD/60USD for the compute module, we expect the computers to cost somewhere around $100-$200USD depending on the specs and configuration.

That being said, since we don’t need to have certain components and other parts to support the onboard computer directly, some of the cost of the computer is offset by the lower cost of the SLB itself.

We’ve decided to split the development of the SLB into two parts, one for the board itself, which will use grblHAL, a new, more advanced firmware and all of the improved motor control and drivers, and the computer itself. This means that the computer will live off the board in one fashion or the other.

While it would have been really cool to have the whole system integrated, we believe that by dividing and conquering, we can have the main portion of the SuperLongBoard out of the development process and into production first, and focus on the computer addition after. We felt like we could tackle some of the main problems with the current LongBoard with the new controller, and that it would be better to have the improvements we’ve already developed reach users sooner rather than having everything wait on further development on the onboard computer side.

This means that users will still need to connect their computers to the board to control their machines when the first batch of SLBs release, but better communication protocols, electronics, and shielding will make the USB connection significantly more reliable than before. Andrew, our main developer on this project, assures me that unreliable connections that cause issues with some users with the current board will be a thing of the past.

This version of the SLB natively supports communication over Ethernet, as well will have onboard storage which allows for streaming onboard rather than through a cable, which will improve reliability as well.

We are making the final design changes to prepare this version of the SLB for prototype production, and we hope to have production boards available near the end of the year.

2023 Vancover Port Strike Resolved

Last week we wrote about a port strike that was going on in Vancouver that was looking to impact the delivery times for our control boards and rotary axis parts. I’m happy to share that the strike has been resolved. However, the ports are still backed up and we are expecting some delays in receiving the rest of our materials.

In the meantime, we’ve ordered another batch of controllers to be produced and shipped rush in the case the delay for controllers causes a major delay in delivery times for pending LongMill orders. We expect this batch to be ready in around 3 weeks.

As we shared in the last update, while we don’t have an exact timeline on when the parts will arrive, we are optimistic that our shipment will be one of the first to be on its way toward Toronto as our container has been unloaded from the ship and is waiting in the railyard. Additionally, since we’ve been approved for ERS (express rail service), which prioritized our cargo first, we expect that this shipment will arrive before the rush order for additional controllers will arrive.

That being said, we still are not sure of the overall impact of the strike, and the backup order should allow us to continue production in the case that delays extend. We’ve received word that parts for the Vortex are already on the way and are expected to arrive end of next week, and we are still waiting for word about the controllers now we have received confirmation that we will receive the controllers around July 28th.

July 2023 Port Strike in Vancouver

Due to a major strike happening in ports on the west coast, some of our shipments coming in from overseas have been delayed. This affects the arrival time of LongBoard controller and certain parts for the Vortex Rotary Axis.

We’ve communicated with our shipping companies who have assured us that our items, due to the timing of the arrivals, are in the railyards awaiting to be sent by train. Thankfully, this puts as one of the first shipments to start moving once the strike ends, but we do not know how long the strike will last.

Based on our research and communication with shipping companies, there is a lot of pressure to resolve the strike, as it is estimated by Canadian Manufacturers and Exporters that the strike is disturbing $500M in trade per day, and creates the potential to damage trade relations with overseas companies.

We are optimistic that the strike will clear soon, and since we are currently in a slower period for shipping, that the impact will be limited. However, we would advise customers to expect a 2-3 week delay for new LongMill orders which require the LongBoard. In the meantime, we are working on alternative methods to get more control boards to continue shipping and production, and we will be pre-packing orders in advance as we wait for the boards to arrive.

The Vortex Rotary Axis is now being assembled and prepared with the parts that we currently have on hand and preparing everything in advance before our last few parts arrive. We continue to keep our set expected shipping date for late-July or early-August.

We will put another post out once this situation resolves and we are closely monitoring the situation. We will reach out to any customers with orders affected by the strike directly.

Vortex Rotary Axis

The Vortex Rotary Axis was launched on June 1st! We now have about half of the batch accounted for, interested customers can still get on the pre-order. This launch was probably the smoothest product launch we’ve ever had. Although some customers weren’t able to make a purchase right at the time we opened up orders due to some website caching, after we had that cleared up, the rest of the day was pretty uneventful. I just want to thank and congratulate everyone who worked on this project as all of the prep work, testing, and resource development that went into this product made sure we had a smooth launch.

Production for the Vortex Rotary Axis has been ramping up, as we get things made up and printed for shipping in late July. We’ve now received most of the parts for the Rotary Axis, and the last remaining parts we are still waiting on are expected to be ready in the first week of July.

There has also been a substantial amount of resource development done for the Vortex, some of which is now being uploaded to the Vortex Resources. You won’t see everything on there yet much of it is in draft form, we are getting everything ready and set up for launch.

LongMill and Extension Kits

We continue to have fairly short lead times on LongMills, however, we are running low on control boards which may increase lead times for some customers. We expect to reach the end of Batch 8 in August, and have around 270 units left in stock. Pending delivery of new control boards, lead times are expected to be 1-2 weeks, but could extend later this month to +3 weeks. Once we receive the new control boards, we expect lead times to go down again.

Lead times are expected to be short for the time being, but lead times may vary a bit depending on how quicky we can get a few kinks resolved including:

  • We are running low on controller board parts, and we are expecting to restock in the first or second week of July
  • Some rails from production are twisted out of spec. We are currently shipping rails that are within spec, and are waiting on replacements to be made.
  • Some poor threading on T12 Delrin nuts means we are making replacements currently. We expect them to be completed in the next 1-2 weeks, but we don’t expect this to be a bottleneck since we still have quite a few in stock.

We are working hard to get ready for the busy season coming up this fall, which means doing lots of pre-packing, restocking and prep!

Rail twist measurement system

We have a few other things coming down the pipeline, but this is all for today. Make sure to stay tuned for the next update.
