| Software notes | The 6840 is a CNC-ready machine: no controller is included in the base configuration. Buyers may choose from a 4-axis Linux driver box (with LinuxCNC), the Sherline/Acorn controller (based on Centroid CNC12, which supports Intercon conversational CAM), or any third-party controller compatible with NEMA 23 stepper motors. The MASSO G3 Touch is not available as an option on this model and is exclusive to the Accu-Pro line. G-code programs can be generated on any operating system using third-party CAM software. | The lathe ships as CNC-ready: NEMA 23 motor mounts and ball screws on both X and Z axes are factory-installed, but axis motors, drivers, control box, and software are not included and must be sourced separately. Compatible with common motion-control platforms such as Mach3, Mach4, and LinuxCNC; the specific configuration is entirely up to the user. |
