Hi All,

Is there anyway I could slow down the stepper pulse width?

I have external stepper drivers and my X and Y need a on time of about 1-5uS and the extruder needs 8uS.
Currently its running at 300nS.

Can I add anything to my local.cfg?

Cheers

I’m not sure… I think you’d need to modify the PRU firmware code, or at least the PCA9685 frequency for this.
