John, Changed the scale to 50. 1 turn of the spindle increases the spindle-pos by 1 now. I thought the phase-Z was responsable for counting the spindle revs.
Running eg G33 Z10 K.1 (assuming .1 mm per turn) moves very "shocky". Also, running G33 Z10 K.2 seems to go up at full speed. Another strange behaviour: running the same command moves in the same "shocky" velocity till Z7, then stands there waiting for some time before continuing... Is there something else I would need in the config?
