UMO+ Problem with circles


Recommended Posts

Posted · UMO+ Problem with circles


I have an UMO+ and since a few weeks I have troubles printing circles. I tried everything, from recalibrating to switching axles and bearings.

Today I changed the bearings but there was no change in print quality.

I tried printing this one as a test: https://www.thingiverse.com/thing:11895

Here is what the result looks like:IMG_20171009_161449.thumb.jpg.b3f294916bcc6e1f70d163e888057dea.jpg

Do you have any suggestions?

Regards, charlie

    this looks so terrible it hurts, there must be lots of wrongs here....aside from the circles, do you get normal looking prints with other parts ?

    Your slicer is cura ? what settings was used on the above print ?

    Yes, the print is terrible.

    But I did just a quick reassembly with the new bearings to see if this got the trick done.

    I should mention that the printer is a second-hand one so I can't say for sure if the parts are all original.

    My last guess would be that the pulleys are wrong but I'd like to have a more educated guess from you guys.

    I did print with standard cura (v.2.3.1) settings, normal quality pla. Other parts came out nicer in the past until the day I discovered the unround circles. Should I try new pulleys? Where can I get some reasonable priced within europe?

    You should maybe try a newer version of cura. I am not sure but maybe the firmware on your printer is newer than the slicer you are using. Also you can see where you can get spare parts on the ultimaker site. They also have a tab showing the retailers closest to you.
