| 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 MASSO G3 Touch is a self-contained CNC controller with a touchscreen display that requires no dedicated PC during machining. G-code programs are authored on any operating system (Windows, macOS, Linux) and transferred via USB flash drive. The controller supports G-code spindle speed control, threading, and built-in conversational programming. WiFi is included as standard. No specific software is required on the host computer: the MASSO G3 handles program execution, axis management, and homing sensor control independently. |
