Re: G-Codes to Stepper Pulses?

Kirk,

If you have the time and want to write your own, then you may want to look
at a program called Indexer LPT. You can write a front end for it in Basic
or C and let it do the timing.

I think most people are better off letting someone else write the program as
we are starting to see good G code converter programs on the market for very
reasonable price. One was mentioned today
(http://pwp.value.net/yeager/cncpro/index.html).
