So all this got me to digging a bit more which has lead to a few more questions. lol
In some reading i saw the same control signals when micro stepping is applied, and it appears the more micro stepping the more (chunky) the line becomes. Does micro stepping affect the step on-time and step space settings?
And kind of related, which is my current setup is set for 16 micro stepping and was set this way when I ran Mach 4 and I wound up going with that setting because my movements weren't smooth enough to maintain smooth cuts. granted I was in MACH4 but should I change to a different setting or am I fine leaving those drivers the way they are?

The micro step ratio does not affect the minimum timing
specifications, but a higher micro step ratio will require
a higher step rate to reach the same velocity. This higher step
rate (and the minimum timing requirements) may limit your
maximum velocity if you choose too high a micro step ratio.
In my experience, micro step ratios > 32 or so are not useful
as the magnetic aberrations in the step motor and current
control accuracy in the drive dominate the position accuracy
and torque ripple values at higher ratios.
