L297's are half or full step devices. They need, at least, 5uS pulse
widths.

Hi all,
I'm currently running a small parallel port converted DM4s mini mill
(with a Campbell Designs BOB) on the demo version of Mach3. I'd like
to try out the alternatives before putting out the money for Mach3 so
I'm in the process of installing EMC.

For clarification: I'm new at this.. so please be gentle ;-)
Sorry, I should have been a little more clear.. If I need to provide
even more details please let me know.
I have inherited this system as a whole. I have no documentation or
specifics about the machine other than it's model

Thanks, but.. been there done that.. There's no information imprinted
or stamped on the Steppers and there's precious little information for

I also followed the suggestion of inverting the step signals. That

I was able to get the steppers working pretty well by inverting the
