I Managed it so far by first setting the rotation with G68 ... Afterwards i Probe and set G92 X0 and a G92 Y0 at the Probing points. Then move to X0 and Y0 and reset the angle to 0 using G69 and reset G92 using G92.1. Then set mc.mcAxisSetPos(inst, 0 , 0) and mc.mcAxisSetPos(inst, 1 , 0) to get X0Y0. At the end i set the agle again with G68... It seems to work, but its not "nice" way. And in the DOCs i found that G92 should not be used ... :-( I hoped that there is a better way .....
