Stepper motors pulsing each other

Hi I've built a simple pen plotter using 3 stepper motors X/Y/pen control. They are driven by an Arduino Uno with Ver3 CNC shield and three drivers.

Everything works very well using GRBL 1.1

Only thing that niggles me is that when I say jog any of the three motors, the motor moves as expected but there is aso a pulse (clunk) from the other two..

Is this normal?

PSU is more than adequate for the job..

Thanks for any pointers

GRBL is a very complex program. You would probably be more successful getting advice on a Forum that specializes in GRBL or CNC.
