Maxpro resolution settings?

Hi,
I am setting up a Camtronics controler with maxpro software but I am
having trouble setting the resolution for the leadscrew and cam setup
I am using. I originally had a Maxnc retrofit kit and I could set the
resolution to give me the correct indicator reading for the imput but
I guess the halfstep of the Camtronics is too much. The maximum
resolution PR.EXE is 65000 and I need twice that, is there anyway
the
programme can be altered rather that changing to a coarser screw.
Thanks, T. Ackland
