Hi chuck,
my profile, or more technically correct, screenset never had a DRO for scaling, I always used G50 and G51 for scaling whenever I've needed it.
Over the last couple of years my screenset has changed as I've built a new machine, much bigger, more powerful and more rigid, using servos
rather than steppers, and so I rather doubt my screenset is of any particular use to you.
What I have found is that my screenset is 99.99% standard as shipped by NFS....all I've really added are those specific features I need for my machine,
things like individual alarm inputs for each servo, and the inputs for a wired pendant for example. All and anything I can possibly require is already built into Mach4.
