What happened?

I cant set right Y axis. I have an endstop on the top side of the machine. When having set positive_direction: false homing is performed properly, but movement via buttons is in the wrong direction and vice-versa..

“Movement via buttons” could mean a lot of things, since you did not respond to the “User Interface Software” question. Go through the flowchart at http://wiki.fluidnc.com/en/support/setup/motion to get the motion dialed in before working on homing.

@MitchBradley I meant fluidnc web interface. How this chart can help me? Swapping direction of a motor will swap axes in corexy setup… Clicking y top button on the web interface will trigger moving down and clicking y down button will trigger moving up.

Get the directions right before homing. Perhaps this will help http://wiki.fluidnc.com/en/config/kinematics#getting-the-directions-right

1. When adding to either of one motor :low in

stepstick:
        direction_pin: I2SO.2:low

It is changing axes, X is Y and Y is X.

2. When adding to both x and y sections same param :low it is causing, that the problem is appearing on X axis instead of Y.

Ok I fixed the issue by swapping cables… :neutral_face: I thought that in corexy no matter if swapping cable or direction in software. I am closing.
