My Z is acting up. When the Z goes to the top it gets too tight and skips steps. If i set the v wheels correctly when the z is all the way up its way too loose when it goes down and if i set it with the z all the way down its too tight to move at the top. Also no matter the v wheel setting the z belt is tighter when the z is at its lowest and looser when it gets closer to the top. I don’t know if this has anything to do with it but in the past the bearing at the top of the z in the plate came apart and inventables sent me a new one.
