Loose Short Axes

Recommended Posts

Hello all,

I have an Ultimaker Original Plus. I've been having an issue with my prints not being geometrically accurate. I believe I have pinned it down to an issue with my short axes and how they fit into the slider blocks. The fit is not tight and therefore the nozzel is shifted at an incorrect angle. Has anyone else has this issue? or have suggestions?

Thanks!

There is a short axis??

Short belt?

There are several issues that can create parts that are not accurate:

- PLA shrinks about .3%

- PLA can stretch and move inward mostly near the bottom 2mm and also all vertical holes are affected big time

- axis not perpendicular/orthogonal

- bottom layer sticks out too much

- play/backlash

This is not complete but it is by far covers the worst issues.

I think you are talking about backlash but if you could photograph your part and explain what dimensions are off and by how much most people can instantly diagnose the issue.

Actually, there's a shorter axis on the Ultimakers, like half a tooth of a GT2. First time I see someone else notices this :)

Also @jackieshaq UMO+ has one of the worst (IMHO, and others) set of pulleys. If you are serious about printing better, the best and first thing you should do is move to GT2 belt

      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
