Faulty mini  

RE: Faulty mini

The printer restarts when the system board supply voltage drops. Or in case of a program error (watchdog). It can be a faulty wiring, a faulty power supply, or a faulty firmware.

RE: Faulty mini

It doesn't Come with any massage on the screen. I've chatted with the prusa support and followed their instruktions and they say that there are no loose wires 🤔

RE: Faulty mini

there are no loose wires

I mean the power lines to the printer. The voltage may fluctuate.

It doesn't Come with any massage on the screen.

Nothing can be displayed on the screen during restart.

I recommend measuring the 24V supply voltage with a memory oscilloscope.

RE: Faulty mini

Restarting the printer can be caused by:

1. button, it can be excluded

2. firmware error, can be reloaded

3. by a drop in the supply voltage

4. motherboard failure

RE: Faulty mini

The funny thing is that it will print some files but others just reboots it..? 

I've tried the same files on my ender 3 and there it works ? 🤔

RE: Faulty mini

That is understandable. Another printer may not have the same problem.

RE: Faulty mini

Have you tried a different USB memory stick? 

RE: Faulty mini

I have been experiencing the same problem for three days. I thought I reset the Mini to factory settings and since then the wizard also comes after switching on and aborts with a reboot.

If I do not run the wizard, then I can not print. At print start or when changing filament the printer crashes.

Wiring looks good.

If I heat the nozzle with the heat bed, then I can print.

I have updated firmware - without success.

RE: Faulty mini

Probably a motherboard failure. Contact support.

Hi @nnhdesign,

could you please extend your info according to this link structure? We want to help you, you have to tell us ... – https://forum.prusa3d.com/forum/english-forum-general-discussion-announcements-and-releases/we-want-to-help-you-you-have-to-tell-us/

RE: Faulty mini

Doesn't help and like i wrote above this i can print litho on it but nothing Else right now 🙁

RE: Faulty mini

I have chatted with the prusa chat for 2 1/2 hours and tried everything they told me and still problems 🙁

RE: Faulty mini

If you do not provide detailes, nobody will be able to help you.

RE: Faulty mini

Can you attach the gcode file which makes your mini crashing?

RE: Faulty mini

It's everything i print beside litho prints that makes it reboot 🙁  can't tell anymore than what the video in the top of this shows 

RE: Faulty mini

I second the suggestion by @3dk to try a different USB flash thumb drive. I have been having gcode corrupted on the stick supplied with the printer which causes the printer to do strange things, including restart the bed leveling in the middle of a print. Plus, it's really easy to try this one - no oscilloscope needed.

RE:

@nnhdesign

1. Did you slice and positioned the stl file with PrusaSlicer and set for MINI - I suspect not, because printing the circle appeares not centred to the sheet?

2. Or did you print directly from gcode file you downloaded?

3. Does it fail all the time or only for specific .gcode files?

4. You did not provide any .stl nor gcode file to verify, the files are good for other MINI printer.
