I apologize for not using standard/correct industry terminology.
The STEP signal being generated by the Duet 2 board from the expansion slot is VERY short on the "active" time. From my understanding, PWM generation devices should have a uniform even wave length, of equal times of the peaks. Just by looking at the frequency wave, the frequency high peaks are barely able to be registered, and the low peaks are the majority of the output. I am trying to make them have equal high/low peaks.
Here is a video better describing what I am trying to have the Duet board output. A uniform symmetrical wave length, at any speed. Increasing the extruder speed (STEP signal PWM output) just makes more peaks. The low peak time is not equal to the high peak time, which is what I am trying to get.

I have experimented with M569 P7 S1 R0 T4 in the config changing it to M569 P7 S1 R0 T40 but have not had success, as this will distort the wave form at higher output rates. Shown in pictures below.
I would also like to have a bigger Vpp (Peak-to-peak voltage) as the duet only output is ~4.5v Is there a way to increase this?
I am connecting to these pins on the control board.
Pin 2) GND
Pin 25) E6_STEP
