Need help calculating my "Steps per " in mach 3 please
« on: March 18, 2015, 08:39:11 AM »
I am hoping someone can help me understand what some of my settings in mach 3 need to be.


The information I have about the ball screw is :
    “The screws are metric 5mm pitch which works out to 5.08TPI.”

Motors:

NEMA 23 Frame,
KL23H2100-50-8B 570 oz In.
Hybrid Stepper Motor
1.8° /200 Steps Per Rev.
5 Amps Current ( Bipolar Parallel),
8-wire, Bi-polar or Unipolar 1/4" dual shaft
Driver:
    Microstepping Driver Microstepping Driver
      KL6050

The formula as I understand it :
  Steps per rev (200) x microstep (?????) x TPI (5.08) =  steps per inch


I cant seem to figure out or understand how to find out the actual steps, since the driver only has a ¼ or 1/8 switch selection.

Confused. Any help appreciated

If you set the drive to 1/4 microstepping, then multiply the steps 4x. If you set it to 1/8, then multiply x8.
