Problem with alignment of the UMO

[walterprojunior 0]

Hey guys

Im having trouble with my UMO

I don't know why, but when i print something, it starts well, printing as it should, but as it goes, at a random height, it suddenly prints wrong:

So what it does is it continues printing the object, but like a cm upper than normal so at the end, the object is like "dislocated" and useless...

I'm working on a Final project for college and I need this issue to be fixed...

Could this things solve the problem?:

-install newest version of CURA

-Verify the axis and so on

THX for helping!

Sounds like a slipping pulley to me. Check that the pulleys are securely fastened to the rods. The easiest way to check is to draw a little line with a pen on the pulley and rod. Then print something and when the print fails check if the marks have moved in relation to each other. Tighten all the set screws nice and tight.

Well it looks as if the problem is solved… After numerous tests, I finally tried downgrading CURA to an old version (14.09) and it seems to be working...

A big thank to your help as I'm sure it helped fastening strongly the pulleys
