Hi apologies if this has been covered anywhere else but how do I wire a standard Ormerod Z-probe to Duet 0.8.5 board.?
If I understand it correctly the Z-probe was wired to AD14, AD12, +3V and GND on previous versions of the Duet.
The 0.8.5 board has the seperate "PROBE" pins which are 3.3v, PC10,GND and AD12. Do I just ignore the PC10 pin and pick up the AD14 pin as before or how should I approach this?

I worked this out over here. If you're following the same colours from RRP, this will work:

Orange/red = AD12
Yellow = GND
Blue = PC10
Green = 3V3

Yes the 0.8.5 board uses PC10 for the modulation signal instead of AD14. Both my firmware fork and chrishamm's detect the board type and drive the correct pin.

Thanks for letting me know David. I have one of your Mini Differential IR boards that I plan to use eventually but I need to get the printer back up and running first.
