Hi i think i have the same issue. But i don’t get which screws you mean. Is it the 6 next to the bearings in the bottomplate? Because if i release these there is no wiggleroom anywhere.

Thanks!

It is these 6 screws. Losen them , wiggle and tighten again. this is what bambu support shared with me. I am going to try it myself if it fixes my issue too.

I tried everything with no success. My P1S has over 4000 hours on it and the Z banding was getting bad.

With some help from AI I worked out the if the bands are about 8mm apart it relates to a full rotation of the lead screws. Meaning there is a wobble in the lead screws or they are bent.

In my case the bearings at the top of the lead screws had started to push out. I lightly tapped them back in place with a 13mm socket and the z bands disappeared completely

Logging in just to say that loosening the 6 screws on the build plate, wiggling, and tightening them seemed to work for me.
