Duet 3 mini5+ 3.3v and 5v rails and steper drives failing.
-
Hi there,
I recently bought a duet 3mini 5+, version 1.1. The instalation went realy well and the printer, a large delta, worked perfectly for over a week.One day I turned on the printer and uploaded some gcode for printing, after doing the delta calibration the printer heated up and started printing, after about half of the first layer the printer suddenly stopped and the 3,3v and 5v indicator leds turned off. After this I turned the printer of and back on again and the 3.3 and 5v rails started working again joust to turn of after a couple of minutes.
After this I checked the entire wiring for short circuits but there were none. I also unpluged everything from the board and its 3.3 and 5v rails kept turning on and off randomly. After this I did some more troubleshooting and while doing this the 3,3 and 5v rails started working again even though I haven't changed anything, so I did a test print to test if everything was ok again. While doing this, notifications started appearing in the web control saying that motor drive 1 detected a short circuit while the conected motor started moving all over the place.
After this I checked the all of the printers wiring again but everything si as it should be. So in the end I contacted ratrig, who sold me the board, and they said that I should ask here for help.
What si causing these problems, is ther something I can try to fix it pr is the board just broken?

Can you send M122 and share the results?
Have you checked the power supply output voltage with a multimeter?
If you unplug everything from the board and connect it to your computer by USB do the 3v/5v LEDs light up solid?
