Y-axis enconder don't work

Did you try to invert the encoder with the toggle in the hardware settings as Gabriel posted in the other thread you replied?

One more thing that could be helpful:

  • Move the Y-axis by hand for like 100mm and check what the encoder’s output is, as you can see in the green box of the picture (SCALED ENCODER).
  • Post a screenshot of this box if this does not fix your issue already.
