| Software notes | CNC-ready version: the machine ships with factory-installed stepper motor mounts on the X and Z axes, but stepper motors and CNC controller are sold separately. The control software depends on the paired system and is not supplied as standard. | 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. |
