I specialize in electronics and not mechanical stuff so I'm a little bit lost here, even after watching some youtube. I don't really know how to interpret my own charts, so I was hoping to get some insight here.
I think my belt tension is probably fine.
The X Resonance has a spike around 125Hz that I haven't been able to smooth out despite tightening most things on the gantry.
Is there anything obvious here that I'm missing?
