Peak 68hz on x and y

Hey guys,
does anyone have an idea what could cause this peak @68hz?? It is on x and y, so i think it is related to a belt or the printhead.

are your hybrid belts already on?

yes

without the hybrid belts there is the same peak but not so high. They peak is also on X graph, so it should not be related to the hybrid belts.

z movement from my understanding is either you have a wobbly toolhead for some reason, (loose toolhead to the carriage or a bad rail) or more likely the toolboard with the ADXL is loose or its mount loose. Have you double checked everything is tight? Also doublecheck both X and Y resonance is measured from the toolboard. Beacon give some wierd measurements due to how/where it is mounted
