Brett,
OK, so not a LinuxCNC to Mach3 Rosetta Stone but a better explanation of what it is Mach3 is asking of me. Good enough!
Basically Mach3 has one field, steps per unit that I am concerned with. I manually figure out the differences based on my steppers, microstepping, ballscrew pitch, any pulleys and gears between them and use THAT value in my steps per unit...
I will check the spreadsheet here in a moment. Thank you for helping!
JB
