Rattling noise from the bed with firmware 3.7.1
Hi,
I’ve just installed the 3.7.1 version from 3.6. I started to print and I realized a strange nosie coming from the printer. I thought its the well known rattling noise from the psu (btw my printer was not the noisy psu version so far) but after some investigation I figured out this noise is produced by the bed, not the psu. When the bed switching from the continous heating to pwm mode (flashing led) the noise appear.
Is there anyone who have the same behaviour?
ps: yes I know the pwm freq was changed in 3.7.1 but with the previous firmwares I did not hear anything.
Printer: MK3

I had the same problem but simply tightened down the nearest heatbed screw to where the noise was originating and that seemed to fix the problem.
