Disabling the motor driver
-
Hey! I want to do a hot change of the feeder motor (without powering off the printer). Connect to a free gpio and apply +5v to it, when GND is applied to this gpio pin, I need the motor driver to turn off and not burn out when the motor connector is disconnected. Gcode M84 E0:1 works long enough, I would like to implement this at the firmware level. Is it possible to do this?

@konk you can use triggers on a GPIO pin to run a macro. Think its M581 to define the pin as a trigger. This page details how to do it:
