Re: Strange situation with stepper motor

Hello to everybody,

yesterday I try to change GRBL config because z-axis of my cnc must stay in tension to withstand weight of axis. I set $1=255 (Step idle delay, milliseconds). 255 = always on.

Stepper motor start clicking repetitively 8-)
Does anyone have any idea why? It's a problem?

For info I have a Nema17 1,5A stepper motor and setting VREF on shield drivers (pololu) to 0.42.

Thanks
