checked and no play on any belt an im getting desperate :/
when im homing all axes and move directly to one of the 4 calibration points the height is perfekt. redoin it at slower speed its about .1 to .2mm too low.
homing and goint to x0 y0 z0 -> perfect height, then move directly to third tower base (about x55 y0 z0) -> perfect height, direct move back to center -> .4mm too low (if it would be a loose belt i would be able to move the paper under the nozzle, but the nozzle is pushed hard into it and only movable after lifting the nozzle .4mm)
doing the same with the 2nd tower ( x-55 y-32 z0) the paper gets stuck at the tower and free again after moving back to center. almost fells like the nozzle is keeping height when moving in positive x/y direction and moving down when moving in negative x/y direction.....
