UM3 stops in the middle of print

[DF-Werkzeugservice 8]

Hi,

since a few days my prints stop at random points. This occurs sometimes after 2 hours, sometimes after 18 hours at different locations in the same gcode.

The printer stops but doesn't show an error message at all. The menu doesn't react to any commands and I have to restart the printer.

In another topic I have read that this can be caused by 3.6 firmware. I've updated it to 4 but the problem still occurs.

Thanks for you help!

It might help us if you can get us the logs of the printer using WeTransfer or something similar.

You can get the log files using the menu: System -> Maintenance -> Diagnostics -> Dump logs to USB.

OK, this night it showed ER18 communication problem with the print head after stopping...

This would have put the log files onto the USB drive.

Please send the log files to us, using WeTransfer, so we can analyze.

But mostly, this is caused by some problem with the cable getting loose in the printhead.
