Interesting, ill look into that. Thanks for the suggestion.

I have a weird issue that Ive never seen before. ON some taller parts, Ive been noticing that the layer lines start to get "wavy." While this term is typically a speed/vibration issue, I dont think this is my situation. As you can see, it almost looks more like Z wobble, potentially a bent lead screw. But those wider layers are actually wider ALL THE WAY AROUND the part. (not just one side, indicating wobble) Originally, I had thought my belts were worn out, since I had 6500+ hours on the machine, but I just replaced all the belts and blocks and the issue remains. Any ideas on what I should look for or what to test? ps: Ill be out of the office for a few days, so if I don't respond right away, I didn't abandon this post. :-)

Yep, for sure. About $0.50/hr of run time (not counting material). Now the question is, would these numbers justify a Form 3 resin printer? hmm... Awesome, exactly what I was looking for. Ill see if I can't get these parts on order. I just need the 2 kits right? Short belts + long belts?

@gr5 yep, we print a lot over here! But I am sure other people print way more. Looks like ~6000 meters across all of my cores. (why doesnt the UM3 just keep track of all this data itself?) Ill check out fbrc8.com, I believe I purchased some stuff from them before. Any other things I should replace while I am in there? Just for fun, I looked up my matterhackers PO's, since July 2018 I purchased 43 spools of filament. (mostly 1kg MH Pro Gray or Silver Tough PLA). That equals about 5420 meters (based on 126 meters per 1kg spool). Prior to 2018 I used a credit card, so I have no good way of figuring out how much I bought prior to that date. But the math seems pretty close!

@gr5 is replacing these belts after a while pretty typical? My UM3 is making a similar creaking noise. I just checked and between my 3 AA cores, looks like I have about 6550 hours on the printer. There is a noticeable amount of black powder on top of the stepper motors, I am guessing this is from the belts rubbing on the inside of the pulleys?
