Hey everyone. We’re excited to share that the SLB will be launching on Dec 4, 2023. Chris and our development team have been going full bore in bug fixing, testing, and doing the final prep to get the SLB ready for production.

SuperLongBoard
The SuperLongBoard 5xHAL is a next-generation 32-bit controller for the LongMill, and is open source for other CNCs brands.
This controller is not compatible with the AltMill CNC.
Our SLB features:
- Faster movement and jogging speeds
- Quieter motors
- CNC status lights with support for external lighting
- Safe E-stop depowers motors and disables accessories
- Programmable action buttons to suit your workflow
- Faster probing and higher sensitivity with touch plates
- Higher level spindle control using RS485**
- Smoother and faster laser motion and engraving
- Independent 4th/Rotary axis output for simultaneous 4-axis cutting
- USB-C and Ethernet connectivity to computer with extensive shielding and onboard ferrites to improve communication reliability
*Huanyang v1 and P2A, and H-100 currently tested to work out-of-the-box. More to be added in the future.
Note: The SLB does not ship with a power supply. The SuperLongBoard requires a 24volt DC 12.5 amp power supply.
Note: If you purchased the LongMill MK2.5 or LongMill MK2.5 Beginner’s Kit, the SLB controller and power supply are already included.
There are simply too many features and updates to share in one blog post, but we do have lots of different content and information you can check out to find out more about the SLB on the Youtube video, the product page, and our blog article, Next Big SLB Update .
