Posted · Weird wobble going on ?

my office ultimaker is running really well.

But yesterday, when i print any thing, there seems to be a little graduate wobble appearing on my prints.

see the picture below.

what could the reason for this little annoying thing be ?

thanks guys.

Ian :-)

    just a guess, but if the object has little fill with thin walls, skeinforge puts a solid layer down when it thinks it needs extra support inside. maybe at those layers you are getting more shrinking thus creating the narrower layer. as i said, just a guess. maybe try increasing the wall thickness and fill.

    I've never seen a print with poor surface quality like that from k'slicer, especially not when you print at 50 microns resolution.

    I'm assuming your model has smooth exterior walls? and that your z threaded rod isn't wobbling around madly because it's become unscrewed or something?

    oh, and that you've told us what slicer and what settings you used of course ;)

    it's PLA right? 230 is pretty hot, tho it shouldn't be doing that. and 70 is pretty slow, so it explains the melted tip at least.

    is this a model you can share or on thingiverse? maybe the clue is in the model - those deep bands approx. every 10mm would be the ones to be most worried about. the other irregularities are just due to Cura I'm afraid - you can fix those just by upgrading to k'slicer.

    It could be a flow (filament feed) problem.

    Can you see any horizontal irregularities inside the ruts?

    As others suggested it could be a Cura problem too, did you notice the print changed speeds markedly on or around those layers?

    Is your platform slipping?

    I got the same thing only worse on a print I did a couple of days ago. I haven't yet got to the bottom of it either. I am going to check the alignment and use a different PLA.

    Try loosening and tightening the pulleys on the motors. Also make sure the short belts on the motors are stretched good and tight without rubbing on anything.
