Duet lost connection to SBC
-
I've had an issue this morning with my duet board losing connection to the RPI or perhaps the otherway around. The RPI/DWC says that it has lost connection with the duet board and says it is waiting for connection pin. I then power cycled the machine and everything was fine. I then had it happen again when I submitted a print job, this time I was able to hit the emergency stop button on the DWC and oddly the board rebooted and reconnected. Its a strange issue but it happened twice this morning to me. Anyone else have that happen ever?

Yes is being investigated I been told but check and make sure your wiring is not crossing causing transients static as I believe that can be a cause .

@Carlo I’ve been running the printer fine for weeks. It just happened twice today. I’m pretty sure the wiring is fine. It is all in an enclosure that’s a bit of a pain to access so it will take some time to check that.

Are you running RRF 3.1.1 and DSF 3.1.1 ?

Yours issue may be slightly different to mine as your setup was working...though out of interest are there any signs ?
for instance my motors start screaming and motion goes haywire anything like that or is it a simply lost connection printer pauses ?Cheers

could it be the slicer output and not the passing of time that has changed?
I.e. can you print an old gcode file without issues? Unfortunately a bit of a wasteful test unless you need an old part.

@bearer I'm not sure, I don't know if it has anything to do with the slicer. The first time I had it happen I was trying to send an extrude 10mm of filament command using the DWC controls. The next time it happened was from a print. It just happened again to me.
I'm trying to get a print started and then realized while it was warming up that I had the wrong filament loaded, so I paused it and changed the filament. When it resumed printing it stopped mid tool path and just sat there. I paused it and resumed again. Then something really wrong happened and the bed crashed so hard into my tool that the glass broke. After the E-stop was pressed. After rebooting it, I preheated the chamber and bed. Then I went to send the job and it lost connection again. But again the E-stop worked to reset the board. It is now printing just fine like nothing happened.

that puts it 100% on DWC/RFF so never mind my comment.
