Hello
I am not sure if this is a hardware or a software problem.
When I print a test circle with a wall thickness of 0.8mm then, it is not everywhere that the two walls touch each other.
I have tightened all belts and calibrated parallelism on small rods
Printer: Ulitmaker orginal +
Design tool: 123D Design
Slicing software: Cura
Cura settinge see pic.
thank you in advance
