  1. Well .... that worked for me! :):):)

    Thank you very much for your help.

    The problem was in the pulley as you said, it was too close to the wall. I have removed the cover, removed the motor and moved the pulley closer to the motor. Now is printing straight!

    So thanks a lot again!

    Best regards,

  2. UM1 or UM2? It depends - if you have sudden moves in only one axis and they tend to happen in large amounts (>1mm per layer) and all at once, it is usually a loose setscrew on a pulley.

    If the problem is that the part has a gradual lean it means it is missing a step or two on every layer consistently and is usually caused by something rubbing. Almost always the thing rubbing is the short belt or one of the short belt pulleys for that axis. So you want to move those pulleys farther from the wall of the UM to keep the belt from rubbing. Another symptom is sometimes you see black powder as the belt gets pulverized or you hear squeaking on UM2 where pulley is touching the wall. In all cases the solution is to move the pulley closer to the motor or away from the wall. It should be almost touching the motor. On the UM1 if you used the plastic spacers you need to add one washer under each of the plastic standoffs to move the belt farther from the wood.

    Can you supply a picture of a "leaning right side" print? And is this a UM Original or UM2?

     

    Gr5, thanks for your info. The printer is UM2. I'll check this during the day, here is the photo of the "leaning"

  3. Dear Ultimaker family,

    this is my first post, as a fresh Ultimaker owner for a week now, I am getting frustrated on this same topic. I had printed several test prints and all of them are leaning on the right side. Tightening the motors and shafts is getting me nowhere. Why I have to bother with this issue, my Ultimaker is brand new!

    Any new suggestions?

    Best regards.
