I need to compare my pulleys moving/oscillating like this to the average normal, support told me this is normal and nothing to worry about then i thought i jump here and see if people can yes/no that and maybe also make a video. For me this seems not normal, maybe this can cause oscillation on the belt making the belt path longer and shorter.
Oh, and its not about the belt moving up and down its the pulley, its “wobbling”
Do you think the whole pulley is wobbling? To me it looks like the lip/rim of the pulley is out of round (and that mould mark doesn’t help). But the body doesn’t seem to wobble, nor does the surface of the belt riding on it…? Hard to be sure ofc. If you place something like a small screwdriver (or dial gauge… (-: ) lightly against the belt at the roller, can you feel oscillations?
-Max
I tryed measuring the belt itself, wich ofcourse ended up in too much friction since the shoulder is already visibly moving i would need a roller dial / those fingerdials for roundness measuring at the belt to see if it makes any impact
At the lower stepper, the impact on the belt is not visible but at the upper stepper it translates SLIGHTLY into the belt visible ( like if you turn your flat hand radial left right ? ) , tbh i didnt really look close at the lower stepper. In general it would be nice to have some other videos to compare and maybe show support if it is or isnt normal pulley movement.
