AMS no power

Printer randomly hard reset itself (full power cycle) while I was troubleshooting a “failed to pullback error”. When the printer came back on the AMS had no power, and now the 24V out from the printer at the 4 pin connector is dead, reading 0V. It appears I somehow lost my 24V supply inside the printer. O have opened a ticket, but curious if anybody has experienced this before?

I have not had this problem.

Is the AP board led or printer lcd screen still working I think it is by what you said ?

Have you checked the MC board ams connector or see if 24v @ the pin ?

Printer is currently printing completely fine via the normal spool reel. Seems to be only a 24V out from
The AMS plug issue as everything else is fine.

Well we know the 24v power supply is ok then I would check the ams connector @ the MC board and check the 4 pin harness from board to the back of the printer.

If that is all good then the MC board has failed to output 24v to ams.

Keep us updated :v:

am currently having the same issues. I can’t open the AMS to get the board. Also printer print fine form normal spool.

Tbh i think there has been a surge on to the AMS that as cause this. it turned on and and then all of a sudden just short but the printer never powered down.

You’ll need to put a support ticket in. All the plugs on the AMS/Buffer/Extruder etc are not hot swappable and can cause issue if either loose or plugged while the printer is switched on, if you find a loose plug turn the printer off before going further. I had an AMS board fail and it wouldn’t power up or show on the screen.
