Ressurection of a thread, I know, but I have followed the instructions from Hood, thanks, but I seem to be getting only a one-hit, ie a z- or a z+, then no other movement, (this may be the correct action for THC, I don't know) and it doesn't seem to be related depthwise to the settings on the plasma screen, where the minus is .01, but I am getting about 1mm. Any ideas?
