| 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 4029CR ships without a controller or software: the control system integration is entirely the user's responsibility. It is compatible with common solutions in the Taig and DIY builder ecosystem, including Mach3, Mach4, and LinuxCNC, paired with NEMA 23 motor drivers (motor mounts are included). Software choice depends entirely on the control hardware selected. |
