Hey Brian,
I was absolutely delighted to find the Plugin auto installed with the latest Mach4 version, it instantly almost got me back up to mach3 usability levels, I only had some minor issues with it:
Is it possible to use the analog triggers as a jog rate modifier ? I had it set up that way in mach3 - A fully tilted Joystick only jogged about 10% max jog rate but when you gradually pulled the analog trigger it speed up to full jogging speed.
This enables more granular movement approaching the work piece and also works as a "safety" of sorts as dropping the controller on a joystick never results in a full tilt jogging move.
I set up the increment modifier button, and it worked great but i think you can reduce the rumble by a lot, its a welcome reminder but it doesn't need to fling the controller out of one's hand

This is a quote from you "Also you can change the inc amount in the registers for the Xbox controller." How do i do that ?
And one more point; there doesn't seem to be any official documentation on the Plugin, it's almost impossible to google as well such a important feature to many hobby users should jump right into view if Xbox / mach4 is searched for.
Anyhow, thank you so much for your work, I've been sorely disappointed by mach4 so far for my simple router and the Plugin does a lot to alleviate that.
