Re: Did belt tension break my stepper shaft? - 10 years ago
QuoteTomek Did you have a chance to check out the other end of the shaft, like where the pulley is on? So the shaft you've just tested gives you a baseline from which you can tell if the other end of the shaft is much softer or the same/similar. My reasoning being is that the shaft is almost certainly hardened. It broke in a clean fracture, and it also probably broke after a lot of repeated moby Megaman - Mechanics

So I ran the file across the shaft as suggested. I didn't really feel too much bite, but it definitely removed a bit of material. Took a picture after a few passes.by Megaman - Mechanics

QuoteMetalmann "had recently tightened it in such a way that it would sound like a low note when plucked." Hard to say, but that tells me that the tension was too tight. Could be cheap,low grade, metal shaft material. It's not good on other components, if you are plucking too many notes. That's coming from a Machinist and Musician. You should witness the slack/slop, in belts of large equipby Megaman - Mechanics

Thanks for your replies, I guess we won't worry about it happening again and it being our fault. Mounting the pulley as close as possible to the stepper housing makes sense though, thanks -Hugoby Megaman - Mechanics

Hello, we were recently printing a large object (19 hours)on our german reprap X400 3d printer... I'm not sure when it happened, everything was going well, stepped out for 10 minutes and when I returned the extruder was "printing" on air, in a part of the plate that had nothing to do with the print... Long story short, disasembled the Y axis carriage and discovered that the shaft for one of the Yby Megaman - Mechanics
