Spindle as axis doesn't run smooth.
« on: April 21, 2018, 12:07:52 PM »
I have a GSK Servo Spindle.  Inside the Spindle Drive, I can run it via Step and Direction or 0-10V. 
I have it set up to run 0-10V great.
I have to switch it to position mode and then it will read the step and direction from Mach4.  It is not smooth though.  It is very jerky.  Even when I make it an Axis and Jog it, it is jerky.

Now the kicker, I test the motion inside the HiCON Plugin Configuration.  Motion is smooth.  I have steps, velocity, and acceleration set exactly the same in Mach4 config.

So, I'm wondering what is different when I run stuff in Mach vs just the plugin confg screen.

hmm.... most likely the accel and vel are still not correct in mach config.

Do the Plugin Config Screen and Mach interpret the pulse train differently?
