After a lot fo z-Axis calibration to make the print finally stick, I just noticed the object got loose and moved a bit. That of course ruined the print. When I tried again I noticed that now hardly filament comes out of the nozzle. The extruder "cracks"from time to time as it cannot forward the filament that fast. How do I
- a make the print stick to the buildplate
- b de-clog the nozzle?
