Thanks for pointing out I had my screws on the wrong spots.
But I don't think that it would any difference in the problem that the bearing is stuck against the PLA and not close enough to the extruder gear.
I think just printed it to hot and messed up the dimensions, to bad. I might try again later after I have fine tuned my machine.
