| Software notes | The machine is sold without a control unit and CNC software, offering maximum architectural freedom. The user must connect the stepper motors (via the three included standard SUB-D 9-pole connectors) to a third-party controller, allowing the use of firmware like GRBL, LinuxCNC, or Mach3 depending on the chosen electronics. | The machine ships without electronics and without software: the axes are prepared for stepper motors, so the choice of controller (GRBL, Mach3, LinuxCNC) and CAM is up to the buyer. Sherline sells its own complete CNC kits separately. |
