@crap I totally feel that. This code was not my first attempt, I think I tried about 3 of the things that you did before I got this working. There was a lot of trial and error and watching the output via my logic analyzer.

RE: Pendant problems on Workbee with Duet2 wifi RR3posted in CNC
@jvp79 You want the port next to the z-probe. The other is for the SD card slot on the PanelDue.
If the e-stop doesn't cause the Duet to e-stop then you don't have the communications line wired up right. Check those connections again.
