Still struggling to get my laser mapped to Z-min, or any usable pin, on mini-Rambo for PWM. Would appreciate somebody helping with the specific change in pins I need.
Fan pin, or if you already have something plugged in fan pin1
I can’t use the fan pin because it is 12v and I need 5v. I posted my issue in no less than 6 places and haven’t really received any feedback.
I don’t know the miniRambo preferring Arduino Uno, Mega and Rambo for laser but have you been to these?

Here’s the new version of that doc:

Just change:
#define FAN_PIN 8
to
#define FAN_PIN 23
