Yes, the Xbox360 plugin does allow assignment of mach button pushes. THC up and THC down are not among the available choices though. TP, I believe you are right that the Galil plugin omits code for the THC up down buttons. I am currently working on setting up 2 buttons to command the Galil directly using the NotifyPlugins command. I will try PR,,4000;BGZ and PR,,-4000;BGZ. This should work unless NotifyPlugins is not allowed during a mach code run. Of course all of a sudden now this thread belongs under the Galil topic. Oh, and by the way those of you that have never played with Galil and servos are missing out. Steppers are so boring. For less than $500 you can pick up on e-bay a Galil 18x2 card, breakout and cable. Add to that a couple of small, cheap DC motors with encoders, power supply, and a couple of drives and you are ready to go. The Galil plugin for mach works flawlessly in my shop.
