Noisy non-printing moves in stealth mode

Dec 08, 2018 5:07 pm

I really like how quiet the MK3 is in stealth mode. I have it running in my appartment over night and it is inaudible.
Well, it used to be. Lately, I noticed loud non-print moves even in stealth mode. I am not sure, but would guess it got worse with the latest FW 3.5.0. I had to reduce the speed of the printing moves to 50 mm/s and non-printing to 30 mm/s to get it back to silent mode.

Is this a bug or intentional? Sifting through all recent commits on github is rather difficult and I have not been able to find out if there were recent firmware changes in motor current (or control mode).

you're talking about travel moves?

try some move commands in terminal to see if its tied to a certain speed or axis

I tried moving the print head in Pronterface and the machine is very noisy at 3000 mm/min, but quiet at 2000 and 4000.
BTW this is with modified (no fan whine for PETG) 3.4.1 firmware.
It seems there is some kind of resonance at 3000 mm/min (50 mm/s). Unfortunately we can't tell Slic3r to keep away from this speed, so it has to be below it (looks like 30 mm/s max).
