printing works so far but the leveling seems to be bad, because in the early layers the nozzle scrached over the surface. The model i tried was 4x4cm. When the calibration is running the red Led always flashes when the nozzle hits the ground but if i check the individual XYZ-Axes the nozzle hits the plate so hard that the calibration is gone, what seems to show there is something wrong when it stores the calibration. One idea i had was a firmware update but as far as i know there is none for the K8800 yet.
Thanks in advance
