two peaks on belt tension

they're just about the same. but idk what to do about the secondary peak. my printer does NOT like printing around 100-120mm/s, but is perfectly quiet below and above that range.

frequency response comparison graph, moves the printed at 45 degrees angle, so the printer will vibrate both at Y axis resonance frequency and on X axis resonance frequency. it's good that you have 2 peaks
