I recently upgraded my shapeoko from an Arduino Uno to a mega and I am using a CNC Stepper Shield designed for the Uno. I realized that the pinout wasn't the same with GRBL for both boards. Is there a ...

I compiled to mega version and uploaded to an arduino mega. I can communicate with grbl by universal gcode sender. But my old setup (i made a shield for my old arduino uno) doesnt work with the mega.

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

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 ...
