| Software notes | The machine includes neither a controller nor software: the choice of control ecosystem is entirely up to the user. Proxxon sells the complete CNC kit separately (NO 24 500), which includes a proprietary Windows-compatible control unit via RS-232/USB. Alternatively, the machine is compatible with third-party controllers that handle stepper motors through a standard interface; the axis connections are factory-prepared. Open-source software such as Mach3, LinuxCNC or equivalent solutions has been used successfully by community members, but these are not officially supported configurations by Proxxon. | 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. |
