Since the Computer sits on top of the controller I'm only running
perhaps a foot of ribbon or USB cable which would seem to assist in
preventing some of the problems people are describing. I've killed
everything on the computer other than Mach3 as even though these are
'light industrial' there is no reason to use the machine fore anything else.

I'm having a little trouble identifying the options available for 'Taig'
size machine control. I keep hitting 'Torch Height Control' ... Do you
do an Ether-Cut package which would support 3or4 steppers via step and
direction?
