Tom and Moray thank you for all your help. Definitely confusing to me and I'm sure I did a poor job of describing what I was seeing. I've learned alot how the system works. The resolution was changing 3 to -1 in DefineCoordSystem. Thanks again

I have tried everything suggested including changing out the KStep board. It just doesn't want to drive both motors in the same direction. Changing the polarity on one of the coils doesn't change the direction. It's weird but probably operator error. Thank you all

The motors are not the problem since the problem stayed with channel 3. Here's the latest Init file I compiled, downloaded and ran. I have another KStep board that I could try. It baffles me it works so well in step response and not from the display. Thank you again for all your help.

The problem could be a bad motor. Channel 1 is the master of Channel 3 that both drive the Y axis. I have removed the motors from the ball screws for easy visual aid. In step response channel 1 moves drives both 1 and 3 properly to my eye. In channel 3 the move drives only itself properly. I have do...

Screenshot 2024-12-10 143018.png I changed the jog to .75 on the y axis and the growling disappeared. Not sure how that is going reflect maximum travel speed when I run a program. I will continue to for mechanical binding but since it works great in step response for moves of 10 inches +- . Thank y...

In step response the motor runs smoothly. When you move it with the control panel arrows or the gamepad it moves but with alot of growling and some hesitation after it moves 6"either direction. Ideas or direct me to a post that addresses this problem. Thank you

It does the same on the step response. I'm thinking it's the motor because when I swap the X-axis motor with the Z that motor works fine.

X and Y work properly. Z will move down when pressing the rapid down arrow the first time then the second time pushing the rapid down arrow it will go up. The same is true of the up arrow. While running a program it's working fine then all of a sudden it dives into the work .75" when it says it's .2...
