Ringing/Artifacts Only in One Direction?

I've been having print issues where after calibrating input shaper, there is prominent ringing on only one side of a print. This ringing seems to only happen when the y axis moves in the positive direction, so it's not specific to the side but the gcode motion positive y motions.

I've had this problem since I built this vcore 3 500mm. I've swapped all the idlers, flipped every linear rail, swapped the x axis linear rail to mgn 9. Swapped the x extrusion, swapped the belts in the complete 3.1 upgrade. I've swapped the motors, changed the joiners 3 times from the 3.0, aluminum 3.0, 3.1, to the aluminum 3.1 from funssor. I think I've swapped every single possible component of the motion system, I've disassembled the frame so many times to realign, and there's still the same issue on every single print. I've swapped out the cable chain for a chainflex cable, and now I have a canbus system.

Resonances have looked perfect since I made the printer, and so do belt tensions.

I've spent countless hours on this issue I have no idea what's causing it.
