The STEPCRAFT CNC routerhttp://stoneycnc.co.uk/stepcraft-overview/ can be configured as a 3D printer comes with a version of the popular 3D printing slicr software. The 3mm PLA filament is driven using a 4th axis driven stepper. Therefore the 3D printing of the STEPCRAFT machines is based on 4 axis Gcode. We setup the UCCNC with the STEPCRAFT parameters and settings (with some tweaking ) and we are now successfully controlling the STEPCRAFT 3D printer with the UCCNC.
