Absolutely Jeff,
What I'm not seeing is any movement at all on the Machine PC. On my bench test, I have 3000 typed into the "speed" DRO in Mach 3 so when I hit the "spindle" button, it's starts up and increases until it hits the 3000 RPM as shown in the Speed DRO. I can increase it or decrease it with the Speed overide arrows perfectly.
When I connect this the same exact way on my main machine PC, I get no movement at all. Now keep in mind as I mentioned in my first post, the benchtest G540 is working perfectly, the Taig Lathe G540 which connected to my main machine PC is the one that shows no movement.
Thanks,
Dave
