So this is a weird one that I'm not too sure on how to approach next...
The printer has been working flawlessly for a while now, and a few day ago it printed a nice litophane cylinder, so I gave it another, I went away, when I got back, I saw it was missing it's top layers. I assumed the filament got stuck, so I cleaned everything up, made sure it's flowing nicely, and set it to print again.
On the second attempt I was present, and the printer clearly showed 1+ hours of print time left, and then it just finished, at the exact same layer, cooled off and switched to "remove print message".
I assumed it was a slicing error, so I re-sliced everything again in cura, checked in the preview, everything looked alright, I saved it, copied it to a new USB stick, and let it print again. Same thing, 1+ hours left, printer decides it's finished at the exact same layer and ends it.
This is quite a bit issues since those are 13 hour long prints, so it's a lot of wasted time, and it worries me that I have no idea where the issue is. Any ideas?
Do I need to upload the gcode? It's quite large at 80+ MB.
