octopi always stuck on the last layer without executing the end gcode.
printed from sd card. starting the print from the octopi or the lcd is giving me the same result.
What is the problem?
octopi always stuck on the last layer without executing the end gcode.
What did you already try to solve it?
tried removing G4 from the end g code in cura

Hello @floxflux
I found these two:

It seems the SD card file canceled the print job:

How does the end gcode look?
my fan was stuck into the heatsink before. but i fixed it prior to printing the last one. i printed it 3 times, all with the same result.

i did try it with and without the G4 command.
i tried to cancel it while it stuck on the last layer so i can move the z axis manually. because the end gcode wasnt running at all.
