This is a 6 axis version of grbl implemented in Arctos 3D printed robotic arm. Tested in open-loop mode without a gripper. It runs on Arduino MEGA, other boards are not supported for now.

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...

Universal (ish) Arduino grbl opto-coupler interface also works with logic-level pwm In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to ...
