Hey !prusa, maybe you can help me. I have a self-assembled Mk3s+ that I put together about a year ago, but never really used because of the following problem.
If I print on draft quality, it makes it through most prints. I’ve printed a dozen cubes, several brackets, and some other odds and ends.
If I try to print on higher detail settings, however, it behaves very strangely. Most often it’ll just hang, and keep oozing out more plastic. Once in a while, the steppers will keep turning and ram the bed or print head against the ends of their tracks.
I’ve tried updating and downgrading the firmware, different SD cards, etc. to no avail. Support hasn’t been much help either.
Any ideas?
I have used one like this before. There are others out there as well but the concept should be the same. It would help ensure you are level across both of your lead screws.

Have you put the printer through the xyz axis calibration as part of your troubleshooting?

That looks very useful!
I’ve done all the calibrations several times.
Tonight’s print seems to be going uncharacteristically well. Maybe all I need to do to fix my issue is set up a webcam every time I print…
Print failed with an error I haven’t seen before, about max ambient temperature. Guess I’ll pull the board out and give it a look, and try again some other time…

Ended up talking to support and they replaced my mainboard. Works great now!
