Hello,
Yes, tormach took care of it fairly diligently. It required the Mach3 upgrade. The file should be available at the tormach site -

What a difference, the machine makes smooth turns. Even my 4th axis seems to "coast" to a stop.
Of course my new problem is thermal lock or a virus that causes the computer to lock-up around 3pm everyday. Waiting on a new computer to arrive as I can't find the virus or hardware problem.
Not sure if the Mach3 is the final release or a beta for Tormach, but it's wizards are very buggy and incomplete. Don't delete Mach2 in case you need an old wizard to crank out some g-code that works.
