Subject: What is Inverse Distance Per Cycle used for?
I have a very basic question, I'm trying to simply understand the purpose of this parameter.

For example, on my mill, the X-axisl travels 1 inch in 12,800 u-steps. Hence, this equates to
3200 cycles/inch = 12,800/inch * 1/4

So how does KFLOP use the 3200 value that I input on the configuration screen?

Does it use it to scale the plots when I do a move command on the Step Response screen?

Does KFLOP use the 3200 value when interacting withy Mach3?

Any info on this topic would be much appreciated. Thanks, Marlon

Hi Marlon,
 
invDistPerCycle is only used to commutate brushless motors.  It has no effect in Step/Dir Mode.  We really should gray it out when Step/Dir is selected.
 
KFLOP operates entirely in units of uSteps.  The Max Vel, Accel, Jerk should all be set in units of uSteps and Seconds.
 
The Resolution is set in either the Mach3 or KMotionCNC Applications.
 
HTH
