Thank you so much for the insight of how that work and it explains a lot.
But as you stated it would be hunting back and forth.Which i assume it
would have to pulse the step line?
And a number of people have scoped the outputs
the next STEP pulse comes in.

The crackling is random and mainly after jog moves.
The motors are Nema34 and running at 72v and approc 4amps.

What type of motors and voltage are you using, is the crackling random,

when this happens, have you tried unplugging the step and dir(everything

microstepping on the driver itself?
I know I've experienced similar crackling sounds on some stepper drivers

The drivers have been working on mach3 for the last 5years with no

I believe jeff pollard has scoped the output on the dir line and it is
