take pictures of both ends for all four steppers so we can make sure its not a crossed wire. I dont think that explains why it worked in CoreXY mode but its time to turn over every rock to find where your problem is

one other thing, did you crimp any of the stepper wires or are they premade ones. Can you get me pictures of the left and right stepper plug wires and the left and right where they plug into the MCU so I can check wiring order?

yah put it all back the correct way then both wires and config. On calls for a few hours and I'll look at the debug again

its hard to see on my phone right now... what do you mean the whole right side moved? you mean the gantry or the right corexy stepper as well?

WTH. I have no clue. Go ahead and wire it back how the docs say and remap the steppers back to what the docs say as well including for the hybrid steppers. From there test it again and make sure its doing what it was doing about going back and to the left. From there upload a current debug file and I'll look at the configs again

ok. I am not sure where the issue is and we need to try and figure out what stepper is moving and what one is not. Normally I would use the stepper_buzz command I had you try but you said everything was working. Can you try that again and see if they are still working?

really strange... I remember you saying you started with an octopus pro but something was wrong with it so you went back to the octopus. What happened and are you reusing any components like the drivers, etc?

I dont see a good diagram that shows both belt paths on a VC4 but I think this is good enough. I dont know why the gantry is moving in a different direction now, forward and to the right vs backwards and to the left, so we would need to double check the config changes on the swap you made. But either way it shows only the right stepper is moving for some reason as if you look at this diagram, the right stepper moves the toolhead in those directions vs the left one moves it in the opposite direction. Are you Y steppers plugged in right now as I would have suspected they would have held the Y from moving.

on a call and I need to think about the movement being different if that means the stepper or the other parts making it differnt. Give me a hour and I'll see if I can find a few minutes to think about it

the goal is to try to point to the driver, mcu & cable vs the stepper itself
