@dc42 said in Detect Extruder/Hotend during powerup or Print:
That's already supported, and I am using it on my tool changer; except that as the tools concerned use Duet 3 tool boards, the switch is actually on the tool (to save wiring) instead of on the dock. But either way will work, just make sure that if you are not using tool boards, you have enough spare inputs on the Duet for all of the dock switches.
Sounds great. Would you mind giving me a hint on where to start looking (ist there a certain M-code for this)?
My research in the WWW only gave me results for filament-detection or Sensorlese homing.
