is there a formula to set Velocity Units/Minute.
in the machine.ini file shows maxvelocty I assume its the same value as Velocity Units/Minute in motor tuning
so if I change the Velocity Units/Minute to 80 the machine.ini file will change to 3600
so if I change the Velocity Units/Minute to 50 the machine.ini file will change to 2250

I am bad at math so I would like to know how mach4 calculates the values..

Thanks for any info

The velocity in the machine.ini file is in counts/second I think.

If you take your counts per unit for that motor, divide by 60, and then multiply by the velocity you want, you will get the velocity value in the machine.ini file
