Right now I have the spindle set up as a PWM output.
So I do something like this:
S100 M3
G01 X1.0
M5
to turn on the PWM output then turn it off.
Problem is Mach3 and smoothstepper has a delay between the spindle on and the movement.
Instead, I heard I could do:
E1P1
G01 X1.0
E1P0
to turn output1 on/off without the delay.
However, now I lost the PWM capability.
Is there no way to do:
S100 E1P1
G01 X1.0
E1P0
so I can set the duty cycle and turn a PWM output on without the spindle delay?
Why is there a spindle delay anyway? I would think the code should be streamed together. Functionality should be coded with a dwell after the spindle on if that is the desired behavior. Thanks.

Do you have the spindle delay set to 0 on General Config page?

Yes I do have all delays set to 0.
The delay is short def less than a second but enough to burn a spot with a laser.

Ah ok, no mention was made of a laser ;)
Afraid that slight dwell is just a part of Mach, Rev 4 may be better.
