if i do the z-axis calibration all movements and zero-ing works. When i then auto-continue to the test-cut the z-axis motor tries to lift up the clamp-sled/router beyond the height of the z-axis. (very nasty noises, probably damaged spindle). I tried a couple of different aproaches but i always end up with this problem. The z-axis is probably already damaged.
Which parameter limits z-axis movement? I couldnt find it anywhere. Then, is there a documentation for groundcontrol.ini expcept reading the source-code?!
