I was using Shuttle pro on my Mach3.
Great, but it was not reliable. I cleaned the insides a couple of times, and it worked for a while - but
ANYWAY - I bought a VistaCNC Mach3 pendant and installed the plugin.
I tries to disconnect the shuttle pro by clicking the green check mark to change it to a red X - but imediately get an error message and Mach3 shuts down.
How do I disable the shuttle pro?
