Solved: It was my Gcode that was changing the fan because I was using P0 for the hotend fan when I should have been using P1. M106 in the gcode controls P0 by default.

Solved: I wired up as per the second diagram since I have a new revision of the Duet WIFI so the z probe in is ok with 12v

Ok so I ran G29 another 5 times with the bed and hotend off and still got an incrementing error as before.

Changed the probing speed to F100 as suggested and this has solved the problem, have also changed to P25 from P10 in the G31 line.

Thanks for your help.

New lines:

M558 P9 H3 F100 T6000 ; Set Z Probe to type Switch or Digital output where Z probe connector is used. G31 X20 Y0 Z1.35 P25 ; Set Z probe trigger value, offset and trigger height

I did infact have M106 P1 S255 in my starting gcode which is now removed. Nothing in ending script or start.g/stop.g

Removing it from my starting script solved the problem, Thanks mate!

@dc42 Thanks, I'll give that a try then! Brown to V-FAN with the jumper on 5v, blue to GND, and black to Z PROBE IN. No voltage divider needed either?

@gnatman your DWC is out of sync with the firmware i think. I would grade to the latest stable firmware and DWC:
https://github.com/dc42/RepRapFirmware/releases/tag/2.01

make sure you read the Whats New file for all releases in between your current one and 2.01:
