Hi Tom,
I recently hooked up Kflop to the Viper drive I am using to power the X servo motor on our machine.

I want to use the step response screen to show me the tuning of the motor as I make changes. But for some reason I can’t get the servo to move when I hit the test or step buttons when in the Step Response screen.

I know I have the correct outputs to the viper because I can control the viper servos using the jog commands in Kmotion and I have the C program for initiation command working too.

The step response test use to work before on the test bench before the machine was assembled, I was able to hit the button and get the motor to move and see the results on the screen. Is it possible that the parameters in the Step response screen are just too out of wack to move the gantry at all? I reset everything to the settings in the manual and no motion at all. (When I do hit the step or move button the plot still fills in seconds later showing no motion.
