Hi,
to be honest many of the latest Mach4 builds from 5000 inclusive have caused problems. Certain sections of code in 5000 onwards now run that fast that it creates a race condition in many of our
motion control boards. The motion controller manufacturers are scrambling to catch up including Andy at Warp9TD.
Unless there is a specific need to update...don't. I'm still running 6412. It does everything I need and there is nothing in the later builds that offer any advantage so why mess about?
I got paying work to do....that's more important to me.
