This sound is driving me CRAZY
Hello everyone! I got my MK3 a few months ago and LOVE IT!!!
Yesterday, when i got home i realized the printer crashed and stopped because the print lifted from the bed and dislodged.
Now, the printer is making a crazy vibration noise when printing. I attached video.
I touched the power supply, and other parts, and cannot seem to isolate where it is coming from.
Any ideas?

Re: This sound is driving me CRAZY
So which of many sounds is driving you crazy? Diagonal movement?

If you find a solution let me know, I'm having similar issues but came like this from the factory. Bearings are junk. I can't imagine the QA has always been this bad but it seems like many corners are being cut.
Re: This sound is driving me CRAZY
If the printer actually jammed the extruder into the part and the part off the bed so it jammed the Y-Axis ... You may want to pop the bed off and check all the bearings are still snugged down and centered on their seats.

I will take apart the printer this weekend and re-assemble using modded bearing holders. I also bought some high end SKF bearings, i will let everyone know if it makes a difference on Monday.
I got a different surprise this morning when i woke up, and my brand new pei sheet peeled off.. and i used a LOT of windex. I guess its part of the hobby.. I emailed prusa, i hope they send me a replacement sheet. It was only 2 weeks old.
Re: This sound is driving me CRAZY
After 2000 hours on oiled but ungreased bearings I replaced them with higher quality Misumi's (6 row instead of 4 row). Made a difference in stiction, pretty much unnoticeable everywhere else, including noise. But X and Y feel "tighter" in a good way; and less rotational play on the table.
PETG and PEI; I'm guessing you didn't read all the posts about how to prep the sheet before printing large PET pieces. PET damage to PEI is a long time known issue - there are many posts discussing ways to limit the adhesion. Windex - when applied properly - is only one way.
Also - your PEI sheet looks like you've been using sand paper on it?
