You are too loud! Now, you're vibrating too much.

What position should the poti have to get the best voltage?

So he's definitely gone a bit quieter.
I only have a few areas that are very vibrating - but I can't locate them exactly.
Seems to be the X-axis but I don't know spontaneously which of the screws I should tighten even tighter. An idea?

Thanks for the help before! :!:

Hello Mic,

The ideal voltage for the A4988 depends on the version of the stepper drivers ( there are different versions with different sense resistors) it can be either 1.25 (for the 0.1 ohm sense resistors, you can see small resistors on the board with the engraving 100) or 0.65 for the 0.05 ohm sense resistors.

About the vibration unless you find where it comes from, not sure if tightening helps. But try it nontheless, it shouldn't harm :)
Also print some stability feet and put some soft foam underneath it reduces the noise even more
