@RomeoFox @timschneider I confirm that this is a bug in RRF 3.4. I will fix it in RRF 3.4.1.

Temporary workaround: for Duet 3 multiply the nonlinear extrusion A coefficient by 750000 and the B coefficient by (750000)^2. For Duet 2 use 937500 in place of 750000.

Thanks @timschneider for identifying the change that introduced the bug.

Have you checked the probe trigger height at multiple points on the bed?

Touch the nozzle to the bed, set G92 Z0, move up 10mm, test trigger height with G30 S-1.

Is the trigger height consistent at all XY points?

What type of probe is it? Is it affected by magnets or density?

It seems the mesh is working as expected, and that it is the probe results that are incorrect.

Thank you for the tips.

I was finally able to locate the problem after days. It seems to be related to the "Cutting corners" function of the "SuperSlicer". I deactivated it and now the oscillations are back where they should be: approx. 46 Hz.
But now all screws are really, really tight 🙄

Now the

M593 p "zvd" F46 ; input shaping

is sufficient again.

I also lowered the instantaneous speed change and acceleration values a bit. Here is still missing some fine tuning.

That was exactly the problem. Thank you!

I also replaced the original Sandisk ultra with the faster extreme, which resulted in a significant jump in upload speed. It was worth it for that alone.

Can you share your config.g and the results of M98 P"config.g" ?

Thanks for the help.

Thanks for testing.
