My Prints look weird. when ever a print is finished I can see uneven lines. I tightened the z belt and it still did not fix. It’s even making a weird sound when going up or down?
it would help if you include pictures or video.

I don’t know if tightening the z belt caused the “weird sound” but the plastic mount can flex a little which lets the idler tilt a little which lets the belt move to the edge of the idler pulley and rub against the flange that keeps the belt on.
Bambu suggests using some of the supplied grease to lube the edge but you might want to remove some tension if that’s what caused the squeak (guessing).
Ok I will add one when I can!
Thanks for the useful info!
