My P1S has about 244 hours of printing behind it and yesterday I wanted to clean and maintain the printer. So I cleaned a rods and redid the belt tensioning. Because I thought, after so many hours, maybe it could need some tension.
But after the calibration, or better while the printer did the calibration, I noticed a loud noice from the printer. After retensioning again and recalibrating it was still there. So I did some troubleshooting and found out, that it comes from the top right and slightly from the bottom left wheel from the X axis. (I may have to say, that it’s only when there is movement on the X axis.)
So where the tooth of the belt roll on the rollers.
How do I get rid of it? I have no freaking idea. I retensioned the belts like 4 times now. But no luck. It feels like, the belts are a bit to loose… because even if I manualy loosen them more, the noise doesn’t go away.
Look at the idler pulley part of the recommended maintenance
I had to add a small amount of lube to the idlers from the back at the top and bottom of the belts to get rid of squeaking about 1500h of print time ago. And a re-application about 50h ago.
It’s not a squeaking… and I think if it would be that, it wouldn’t just happend the moment I retentioned the belts. https://www.youtube.com/shorts/PzVmTkphZVM
Here is the video of it. you can clearly hear it.
Erm, yeah, that does sound very odd indeed. I have come across something similar to that rattling sound when a poop got trapped under the printer, touching the z-belt.
Could there be something scarping on the XY-belt?
Yeah, I meant that it sounds like there’s something in your XY belts path that is rubbing on the belt teeth.
From my own experience with something in the Z belt path.
I’ve literally taken the same path (cleaning and tensioning routine) and found myself with the same noises from the X-axis pulleys where belt teeth face the pulley.
But from my observation sound is like when a very clean rubber slides on a very clean surface. Or belt tension is a bit high (with the routine from the guide). Or both.
I sadly have no idea, what could cause this sound. I have the printer a little bit apart now and looking at everything. but can’t find anything. So my last option is… sit and cry I have really no idea…
@lolwat I think I got it. I did flush the rollers with alcohol. After it dryed, I used a syringe with a little bit of oil to lub the rollers back up. After that, I just redid the tensioning and calibrated. First it was still there, but I just started to print. And after like… one hour it was gone. It was strange, that the sound was only on the rollers, where the belt moves on the teeth side. But it’s gone. So I’m happy.
the bearing. Do not oil the surface. The belt shouldn’t be oiled!
I just put some drops between the roller and the frame. It kinda worked itself in after some time.
I have really no idea…
