Maslow ring system problem

Hello everyone, iam new to Maslow .
First of all I would like to say that the Maslow CNC is amazing !
I just Finished mine last weekend , it’s working fine and very accurate the only problem iam still having is with the z axis.

When i started my first cut I directly that it was making bumpy movements I noticed that those movements where due the paint on the ring system . I sanded the paint on the inside of the ring and now the bearings are moving smooth over it .

Is this common ?

Yes :slight_smile:

The type of paint job is causing this
After I used sandpaper on the inside it’s working perfect .

Yes I also just sanded the inside of the ring… it should be a lot more smooth now!
