The hardware
The Smoothieboard is a controller for 3D printers, laser cutters and CNC machines. The MKS-SBASE is a cheap chinese clone of the Smoothieboard hardware.
Here are some links to get started: Smoothieboard (official website) Github repository with information on the MKS-SBASE board
Uses at Tkkrlab
We currently have one MKS-SBASE board built into our [Laser_Cutter|laser cutter]].
