OK, here is the new XML, did a Registry keyword wipe, and a hard drive dirty word search and delete. This should be a clean install, Jog rate is 1.5-2 Units/Min, and Feed Rate is still 6-8.
Looking like I will go to a USB controller if there is no joy - It will be twice the price of the Mach3 license but if something doesn't work...
Thanks for any assistance.
