Horrible resonance at specific speed
After it’s all set up with AdXL & input shaped, the ghosting disappears allowing high speed printing.
But why do I get a horrible harmonic resonance at specific speed 98mm/s observed here. I would have thought that horrible noise would be the strongest signal to the input shaper?

this was talked about extensively.. THIS TOPIC NEEDS TO BE PINNED HERE! I just did this and YESY it made a BIG difference

Wow definitively needs to be pinned. Can't wait to try it when this print stops. I'm really surprised by this though - reversing the direction of power into the coils then reversing the direction of the power signals should be the same - unless there's a bug somewhere. I have the same issue on my Voron at 60mm/s
its the 2 coil polarities in relation to each other

is it valid also for z stepper motor?
