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

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
