| 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 includes a PC running Ubuntu Linux with LinuxCNC pre-installed, along with a 4-axis driver board built into the computer chassis. A CD with complete instructions and utilities to convert CAD files and TrueType fonts into G-code is included. The operator must supply an external monitor; keyboard and mouse are provided. LinuxCNC is an open-source CNC control package running real-time on the Linux kernel and is compatible with standard G-code formats. |
