I think your belt paths is going to give you inaccuracies. I’m looking at the belts behind your x/y joints and the belts aren’t parallel there. I can’t remember exactly why that’s bad but I think it ends up with uneven movement across the entire motion range.
I’m not exactly 100% sure on this but I’ve seen people mention similar issues to people doing ender 3 switchwire conversions.
It might even out because it seems like you have the same thing on both both belts behind the gantry but I would look into that.
