Wobbly print

[skvalp]

Tried printing the end cap of the filament holder with just a cut meter of filament. It was ok but not perfect.I also made the worst print yet, with a spider web like walls after. Big holes and just failure. I aborted that print. First cm of layers went ok then it just went crap. So problem didn?t start at same place as yesterday but was similiar but worse. This was with the filament in it?s holder and just before the better print I mentioned above. The more I search the more possible problems I find. I just don?t where to look. Z-axis motor need a spacer? Clogging in the nozzle? Filament not unvinding properly?
