I have my machine setup in inches using:
- 1/2-10 ACME lead screws
- 1.8 degree, 270oz steppers (200 steps per rev)
- 1/8 microstepping drivers

My motor tuning in Mach3 is
Steps per Revolution = 20000
Velosity = 60
Acceleration = 1
Step Pulse= 5
Dir Pulse = 5
These values are from memory as I'm not in front of the router PC.
My router is super smooth with these settings, I'm very happy with its operation.
Now, I want to start using Metric units and I do not want to mess with my Imperial setup, will Mach3 allow me to create another profile with different motor tuning?
As well what would the settings be for my motor tuning for me to setup metric. I have to convert the 10TPI screw to metric (turns per mm or cm) I do not think there will be many turns per mm.

Thanks for the help.
