interaction between axis
just assembled the MK4S to CORE One conversion kit and I'm having this problem:
When I move the Nextruder on the X-axis using the screen knob, the gantry also moves a bit (see attached video). This interaction between X and Y makes it impossible to calibrate X and Y.
Any suggestions on what I've done wrong?

RE:
Have you installed the pulleys correctly on the X and Y motors? One needs to have the toothed part on top, one on the bottom end, so they properly engage with the belts. It is a common trap to install the second one "on autopilot", the same as the first -- but it needs to be the other way round.
Or the screws which lock the pulleys to the motor axles might be loose on one side.
