Oopsie! Looks like my printer lost an awful lot of weight or my 1up has a 2up belt. Dang! So close. I also got an extra 2up bearing and the 2up bottom. I don’t know how many of those humongous bolts the 2up uses, but I have three left over. But the show-stopper is the wrong belt.
Man, I know that I go on about this a lot but QU-BD clearly have really poor quality control. I don’t think I’ve heard anyone say their 1up didn’t have some issue. Let us know how you get on with their customer service.
@Rojer_Wisner I recommend cutting the belt and anchoring it to the x carriage quick fix as long as the teeth match the pulley
Also add a half twist on the belt. This will make for smoother rolling across the idler bearing
@D_Rob hmm, sounds interesting. This would seem to be a permanent fix but would it eliminate the possibility of reverting back to the original design?
I’ll have to look and see where and how I might go about doing that. This is my first home built printer. I know my Y-belt tension is too high also. So I’ll need to get that adjusted correctly too. The Joy Of Belts.
With the half twist in the belt the teeth can line up to help hold them together and wrap the hell out of this joint with dental floss tightly then tie it off. Find where the belt is supposed to anchor on your carriage. And anchor it there if possible just to the side of your joint. If not modify it to be right on the joint. Maybe make your first successful print be a clip that joints the belt and connects it to the carriage.
@D_Rob @Rojer_Wisner I’ll vouch for the half twist union. I had the opposite problem on my CNC - belt was way to short (the joys of salvage). So I joined 2 of them together. Works like a charm - here’s a picture of the joint being assembled:
Well, I may not be able to attack the problem until Saturday, but I will defiantly consider the suggestions.
