Noisy Y-axis movements
Greetings,
I completed my MK2 assembly last week, and have been slowly making test prints. The first few were from the GCode on the SD card, and last night I printed two calibration items from the Prusa included version of Slic3r.
All the prints look fantastic! Definitely better than my other printer.
Only concern I have is a loud, low, moan when the print bed moves long distances somewhat quickly. It seems to be a vibration that is amplified by the bed or Y-carriage - almost as if the heated bed was not tight, and was vibrating against the Y-carriage.
The printer XYZ calibrations completed successfully with the message, "XYZ calibration ok. X/Y axes are perpendicular."
The dimensions on a 20x20x20mm cube come out very close, and are completely acceptable.
If others have the same noise, and their printers have continued to print well for many hours, than I'll just add the anti-vibration dampeners and accept the noise, but if this is more serious, I'd rather investigate and troubleshoot now.
Here's a like to a short video. You can best hear the noise about 5 seconds into the video. It almost sounds like a fog horn in the recording. Just for reference, that rectangle is 162x74x6mm.
Thanks for any ideas.

Re: Noisy Y-axis movements
Silent mode or highpower mode?
Isn't the Y belt tightened too much?

High power mode.
Good question about the belt tightness. Everything I read talked about making sure it it tight enough. If you think I should loosen it a bit, I certainly can try that.
Re: Noisy Y-axis movements
It is printer, not guitar. Make it tight "just right".
Also try silent mode. If the printer is assembled well, you should be happy with silent mode most of the time.

I'll shoot for "just right."

I will. I did try one print on silent mode. It was definitely quieter, and the small print test finished just fine. I often read on these forums about using high power as a troubleshooting test, so, since my printer came with high power as the default, I figured I would do my initial calibration and "get acquainted" prints with it as shipped from Prusa.

I loosened the belt about two notches (one from each side). Calibration completed fine, but I still had similar noises. I guess I'll just print the anti-vibration dampeners and live with it. At least it does not seem to be negatively impacting the prints.

Sadly, the print quality suffered a little after loosening the belt. The belt still seems to be appropriately tight, and I passed calibration. I also re-adjusted Z-height with Live Z-adjust on the V2Calibration again, so maybe that was the culprit for slight degradation in print quality. I'm not sure.
Re: Noisy Y-axis movements
I am in the same boat. I fumbled around with the heat bed and stripped out one of the mounting screws (they only thread about 3-4 threads in anyways). Replaced the screw with a spare included in the kit with some washers. First thing I noticed was the extruder assembly had gotten loose after the first few prints. I feel like the bearing quality is the culprit here. No matter what tension the zip ties are, after the bearings have "broken in" there is some play. This in no way has affected anything in the quality department other than my ears, which is solved by putting the printer in silent mode. Would be interested to see what others have found.

Did you ever end up fixing this?
