"Phase may be disconnected" action while printing

[engikeneer]

Duet 2 WiFi with RRF3.3 (but would also apply to other boards)

Yesterday I had a print fail because the extruder plug got pulled out at the motor. I'd been rerouting the wiring and obviously got it slightly wrong...
Anyway, when I looked at DWC, I realised that I had a bunch of warnings that the motor may be disconnected. So, the board detected the problem, but didn't respond other than messages in the console.

Ideally I'd like a way to set the behaviour under these conditions. My preference would be for the printer to pause with a warning message (similar to a filament out). However I can see that they may falsely trigger in some cases so not all users might want that.

I couldn't see anything in the docs to set this. Maybe it's possible with daemon.g and the object model?

@engikeneer this feature isn't completely reliable, and Trinamic states in the datasheet that the open-load detection is only intended for debugging. So that's how we have implemented it. Making the response configurable would be possible, but incidents such as yours are so rare that it's hard to justify the effort and code space required.

@dc42 fair point, and I guess the proper answer is to get the wire lengths right and use strain relief next time!
