I noticed that some of my bearings weren’t touching on the y gantry. I saw the procedure to adjust them in another thread. It said you could disconnect the Y stepper and test that the gantry moves from one end to the other. It didn’t mention how much preload you should have on the bearings. Too much and you could prematurely where the bearings or the tube or cause the stepper to stall. If I adjust mine so it moves really freely I’ll always have a couple bearings that don’t make contact with the tube. If I adjust so they all make contact there is some resistance when moving from end to end. Has anyone quantified the amount of preload for these bearings?
