Hi John,
Excellent explanation you have given there.
Not quite sure about this bit though. The terms "active high" or "active low" are meaningful to me and are understood by Mach3 when it comes to setting everything up.

It is not really meaningful to talk about these signals as having active levels since they are doing something whatever level they are.
where the sense of the signal can be active low or active high is arbitrary but the ability to swap the sense can be useful for testing
