Added this at the end of my Ref All Home function in the Screen Load Script:
--Set G30 # variables
mc.mcCntlSetPoundVar(inst,5181,11.7)
mc.mcCntlSetPoundVar(inst,5182,-.5)
mc.mcCntlSetPoundVar(inst,5183,-.02)
mc.mcCntlSetPoundVar(inst,5184,2.00)
mc.mcCntlSetLastError(inst, "G30 # Variables set")
Works! Fire up the control, Ref All Home, G30 Vars are set each time. Goes with my screenset, so no need to remember if/when I upgrade Mach4.
Off to VS Code to work on my post!
