Like i mentioned earlier. It homes z to top and x &y like it should.
Screen button +z goes up and - goes down.
But runnning gcode test crown. The crown would be flipped upside down. Starting from top. If i look at it from 3d point of view.
So it starts to do crown gantry up position. Like z endstop position would be z0 point.
Will check today if i have z axis cables cross plugged and wrong motor direction.
If i put it this way, z axis works sameway as printer with fixed gantry and bed moves up and down.
But it should be the otherway around. Gantry moves up and down logic.
