Just wanted to thank everybody for all the excellent feedback. At the
moment I'm leaning towards this being a cable shielding or grounding
issue with my driver board (as suggested first by, I believe James
Reed). I have had suspicions that I had some sort of grounding problem
for a while,

I would suggest checking this page:
http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Stepper_Drive_Timing
It only has the HCNC pro listed but I believe they use the same driver
chips.
I have the HCNC Pro and have not seen the issues you mention, although like
Terry already mentioned, stepconf uses
One other thing, I would also suggest you disable Idle current reduction
on your controller board if that is an option. I was on the HCNC list for
quite some time and many people had strange issues when idle current
reduction was enabled, apparently the driver chips also have that feature
built in
Thanks for everyone's responses. I get a digest version of the mail
list responses, so I'll go ahead and reply to everybody's at one time.

I haven't spent much time messing with halscope, but I'm not sure how
to best use it here given the intermittent nature of the problem.

Hi,
I don't see value that specifically affects the direction valid time,
but I definitely could be missing something...
Someone will probably chime in here.

Jeffrey,
Are you sure on that 40 inches per sec?
That means you rapid at 2400 inches per min(which is the
way people talk about rapids)
That would be pretty incredible for stepper motors.
Pretty fast steppers run about 300 inches per min.
The step config wizard uses inches per sec.
