VCore 4 500 IDEX Toolheads move when moving gantry in Y

[ocean pine]

My X-belts are tight at 16.9 mm, my Y-belts are slightly more loose at 15.9 mm.
Measured at approx. 10 cm from the front with the heads and gantry approx. in the middle.

attach the y belts

They are attached. Do I have to tension them more ?

home your printer and check if ti works

when moving manually this can happen, nothing to worry about

I do have a problem with homing also, which I will post shortly in a separate post.

It also moves in X when jogging in Y

first make sure both toolheads to move correclty left and right

then if they still move in x when moving y then your y motors are probably reversed

All motors move in the correct direction.

Ok, my bad. The motor for the second toolhead got mixed up with the right Y motor in the setup.
