Define "Fairly quickly".... motion is not really ever fairly quickly, unless your board is designed specifically to work with Mach3 and you have built in 1.5-2 second motion buffers.
I will give it a stab, you can contact me at: poppabear"AT"hughes.net ( replace the "AT" with @ )
I have several plugins published that show my work, on this site, and others.
Another guy is Steve Murphy, he is a Major talent and has the Galil, and Mesa boards under his belt for motion. You can hit him up also.
