I had previously posted about some horizontal line issues I’ve been having, and I tried a lot of the suggestions I got; Unfortunately the issue persists.
I saw a video today, where someone mentioned that these connections that are basically responsible for raising and lowering the printer head should be somewhat loose, and not tight (as I had them).
Does anyone know if this is true? The video creator said that it is to allow for some ‘forgiveness’ between the two screws that drive the printer head up and down.
I cannot see images (“these”), but if you are talking about some wheels, yes they should not be too tight neither too loose. Once tightened you should be able to turn them with your fingers without raising gantry but you should also feel friction.
Ah, it’s the part that the screws actually use to move the head up and down to which I was referring. It’s a couple black circles on the Prusa MK2.
