Hi,
i've built a 350 trident from a formbot kit. Its completely assembled now but it is so loud I can't use it (its in the room next to my office). I expected it to be somewhat in the noise range of my other printer (Enclosed Ender 3 frame,linear rails with SKR2 and BTT 2209. The trident sits right next to the ender which I can't hear at all from the other room. There is heavy vibration on the toolhead at lower speeds, starting at about 25mm/s until 150mm/s. I ran some test prints, print quality is fine but needs some tuning. I get lots of VFA due too vibrations. When I touch the A/B motors while moving i can feel some vibrations but not very strong. The toolhead is vibrating much more, same for the belts. My assumption is A/B motor resonance in combination with enclusure resonance. Or maybe belt rubbing in a place I can't find
Use headphones or hifi for best immersion
printing a firstlayer at 30mm/s
things I already tried:
Is coreXY generally more noisy on x/y movement than bed flingers?
Could this be a electronics problem?
Faulty drivers maybe?
(motor)cables running to close to each other? I had a similar problem on my cnc mill, resolved by using anti-interference capacitors, but in this case the movement was about movement not noise
Any Ideas appreciated

printing a firstlayer at 30mm/s
things I already tried:
- switch from spreadcyle to stealthchop (octopus v1.1, BTT 2209)
- less vibration but horrible grinding noise at higher speeds, I've read that this is normal but my other printer goes up to 600mm/s stealthchop without issues on 2209
- changing motors from formbot moons to new ldo
- no change at all
- checked belt paths for belt debris or any kind of rubbing
- nothing found, everything moves freely without the motors
- removed the lightweight cnc y extrusion from aliexpress
- a little less vibrations in the y extrusion but same noise and toolhead vibration
- reverted from TAP to inductive probe
- better firstlayer,less wobbly toolhead, but maybe totally unrelated to the vibration problem, will investigate later
- reverted to default panel clamps
- a little less vibrations
- put it on a 30kg block of stone and decoupled it from the desk
- desk is not vibrating anymore, but still too loud through the door in the next room
- increase and decrease of motor current
- increase from .8A to 1A helped a bit, decrease to .6 made it worse, need to check motor temps on longer prints...
- when moving the gantry slowly in Y direction by hand the toolhead is shaking a little in x direction (maybe normal, its my first coreXY)
- inputshaper is around 50hz resonance, depending on belt tension
- noise freuqencies measured with smartphone app are around 140hz to 180hz (very inaccurate)
- side and top panels are resonating, if i put my hands on the side panels noise gets dampened
- straight moves in y or x direction resonate most, diagonal moves a little less (except for stealthchop, there diagonal is noisiest)
- VFAs distance is way less than 2mm maybe .1mm
