Or make up custom macros to write to the spindle DRO to change it to whatever gear you want. For example a macro named something like
m101 for pulley 1
m102 for pulley 2
etc etc
The macro for m101 would simply have the following in it.
SetOemDRO(56,1)
m102 would have
SetOemDRO(56,2)
etc etc
Then when you called m101 from MDI or code the pulley would be set to 1, m102 it would be set to 2 etc etc
