3D Printing Forum

Came over to check on a 5 hour print and found the printer like this...
No error on the display or anything

So, why did it just up and stop? No power issues tonight

What firmware are you running?
What did the display show?

Printers using recent versions of the tinkergnome firmware sometimes does this, although I am starting to suspect that it is some more general issue.
Here is a long thread about this: https://github.com/TinkerGnome/Ultimake ... /issues/56

If the heat was on and hotend was still active, most probably is the usb sd has a error.

a) Ejected too son and windows/mac didn't finish writing the gcode
b) The sd card is dead or has a few bad sectors.

Firmware is latest from UM (installed when UM2+ extruder upgrade was completed)

SD card? Well I always eject it per the Cura prompt. Bad sectors...no real way to test that, is there?

Yea, make another file without deleting it, or just try to copy it and check on a txt editor

Viewed the file on the SD card in Notepad++ It's all there

Mystery remains!

I once had a similar error when a small part of a print felt into the Z end stop. But I think you said that you had checked the end stops, correct?

Mechanically seems fine too....did three other prints fine
