The plugin is linked on the CNC4PC site, as linked in my post above. Not sure why they don't include it, or at least a little slip of paper with the link to download. There is a newer plugin, according to Greg, but he told me on the Warp9 forum that it REQUIRES Mach v057 and won't run without 057. I personally am having jog issues after an M6 with Mach 057, so can't use it.
