General Mach Discussion / Re: What is the step/direction pulse width?

Brian,
I look forward to the rewrite. As it is, your Mach 3 manual is still one of the best primers on cnc machining out there.
Whacko,
The AVR-based driver board kit I am going to use for my machine, uses the H11L1M, like you suggest:

A .1 usec rise and fall time is very good, I think. I will be using these boards with the cnc4pc.com multi-function board. It uses the HCPL2531 opto's, which are good - around .4 usec rise time and .3 usec fall time. Still better is the HCPL2360 opto - 20 nsec rise and 30 ns fall time.
