Dynamic settings / dampen vibrations
-
I'm trying to motivate my new Voron 2.4 350x350 to produce consistent print results. Unfortunately, I am struggling with massive oscillations exactly between 35 and 90 mm/sec. The trigger seems to be the excitation of the toothed belt (GT2) on the X-axis.
Here my setup for the dynamic part:M566 X1500 Y1500 Z100 E2000 P1 ; set maximum instantaneous speed changes (mm/min) M203 X60000 Y60000 Z6000 E4000 ; set maximum speeds (mm/min) M201 X5000 Y5000 Z1500 E4000 ; set accelerations (mm/s^2) M593 p "zvd" F15 ; input shaping M572 D0 S0.03 ; pressure advance
Are there any other controls in the software that I have overlooked?

Try halving both the instantaneous speed change and acceleration values?
They both seem rather high.

@romeofox FWIW, I have never seen a Voron 2.4 with a ZVD (resonance) frequency of 15Hz.
It's pretty normal around early 60 Hz X and about late 40 Y unless something is loose.

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 tightNow 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.
