I just finished getting Mach3 setup and operational on my CNC-Step High-Z S-720/T and thought I'd share the settings so others could find them easily. I found a few great threads in the forums and thought I'd contribute my configuration since the T series is slightly different and I am using a Contour Designs ShuttleXpress USB Pendant (very necessary addition). All of my test parts have been correctly scaled and machined so far, I will post back when we have results from our production run of modified waterproof ABS carrying cases.
