I just bought a K8800 but now that I want to print the Vertex keychain this happens:
it looks like he is not printing a part at the back. After 10 seconds I have to stop the print because it gets stuck behind the print. I am using the vertex filament PLA 1,75mm.
I have already calibrated a number of times and saved these settings.
The bars are lubricated and the printer bed is not attached to the holders either.
Any idea what i can do to resolve this problem?
