| Software notes | The machine is prepared for CNC but ships without stepper motors or a CNC controller, which must be purchased separately. Control software is not included in the base configuration. | The system ships with an Ubuntu Linux computer and LinuxCNC preinstalled for 4-axis control, with the driver board and power supply already fitted. The tailstock spindle remains manually controlled. Utilities to convert CAD files or TrueType fonts into G-code are included. |
