Hi,

I am a little confused on the steps per unit. I have a Hurco SM1, .200" pitch on my ballscrews, directly coupled to the servo on the X axis, 1-1 timing pulleys on both the Y & Z axis. 1000 CPR encoders on all 3 axis, Larken Viper servo drives that have the option of 0, 4, 6, or 10 step multiplier. I also have a smoothstepper.

So...

My screw revs per unit = 5

Motor steps per rev = 4000

Mach 3 steps per rev = 20,000 (5 x 4000)

OK, does the step multiplier have any bearing on the Mach 3 steps per rev? Larken recommends 4x multiplier.

Thanks

Tom
