belt shifting
Ok..I have a odd issue that doesn't make any sense. I did a print almost 2 weeks ago and shut the printer off until a day or 2 ago. I started having odd things happening early on in prints. Long story short, the lower belt in the back left hand side was starting to ride up into the other, but ONLY when the print head is moving towards the front of the printer. When you push the print head towards the back it drops back down. It's getting caught on the lower edge of the bearing. I've dropped the stepper out twice now, tried tightening and loosen the belts but nothing has made a difference. Is there something inside that assembly that I can't see causing it? You can see when you have the print head towards the front if you look at the belts in the very back get closer to each other going from right to left. But I can't figure out why it's riding up all of a sudden.
Thanks

Resnetly have been fixing that exact issue, for me it was motor cages, when you install it, holes may not align with holes in metar corner, and so bolts on which idlers are located, would be both tilted but in different direction
something like that
that figure suppose to describe nonalignment of that mechanical assembly (top printer cage and bottom metal corner)
to fix that, I have been just live tunning printed motor cage, by rotating it a bit and trying to check if belt stopped walking up and down
and make sure to not tight very much idlers bolts, because at least for me, it did move idlers out of alignment, and lower belt was moving up and down.
But if they were too lose, my shaper graph did look like garbage
So balance is important

Thank you...lots to think on there. I've been printing with this since late last summer and especially the last month or 2 its been running real good. I put the new Rapido Plus hotend on it and its the smoothest and fastest its ran. Guess time to take the corner apart
Thank you again for the info
oh. if it was fine, then maybe my suggestion is useless...
I had that problem from the start
