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).
