Hi all,
I recently upgraded my M90 with new x-ends and new belt, as nophead described on his blog... After putting everything together, and calibrating it, I get weird errors while printing in X-axis. See album with pictures below... These x-axis erorrs are different every time, sometimes jump is to left, other time to right... really weird.Y-axis is perfect - see smooth walls on rectangular object in pics...

I tried several things, but results remain the same:
tightening the belt
changing the pulley
tightening the grub screw on pulley (pulley does not move - i've marked position with marker, and after print its still on the exact same spot, and holds tight)..
moved the pulley further on the motor shaft / closer to the motor shaft (so that belt would not touch the border on idler - and it does not seem to)...
I have default firmware, with nopheads "slowed-down" XY-accelerations, 4000->2000..
At this moment I am at the loss, of what to do, any any suggestions is welcomed.
thanks,
Jaka
