Thank you very much for your time! 👍
That did the trick.

I needed a normaly open switch so there is no connection between the wires when the filament is loaded.

kind regards,
Leon.

Swapping those two wires wouldn't have caused any damage. What I think must have happened is that either the +5V pin the PanelDue connector got shorted to the +3.3V pin on the Z probe connector, or there must have been a short between either +3.3V or +5V and a wire carrying VIN power. Does that sound possible? Can you identify any chips on the Duet main board that look damaged or are getting hot?

Found the solution already by using a typical Homez.g file for a probe.

G91 ; relative mode
G1 S2 Z4 F200 ; raise head 4mm to ensure it is above the Z probe trigger height
G90 ; back to absolute mode
G1 X100 Y100 F2000 ; put head over the centre of the bed, or wherever you want to probe
G30 ; lower head, stop when probe triggered and set Z to trigger height

Thanks for the help!!

Kind regads,
Leon

Thanks for the info. We will feed this input into planned design changes, and consider getting a TB6600-based driver to test.
