Ian,
Well, I have an admission to make - I'm re-writing (Maintaining) Stepster!
The thing is, so many things could be wrong, and I'm ONLY working with
code (I don't have a CNC Mill - YET - anyone have some cheap ideas for my
Sherline)

There IS a Stepster E-Group at

http://www.egroups.com/list/stepstercnc/

or to subscribe

e-mail

stepstercnc-subscribe@egroups.com

My GUESS is one of 2 things - The most likely is that the 486-66 can't RUN
faster than that, OR you're using steppers that are a bit weak for your
mill, and you loose steps
