This may sound dumb to most of you guys...but how does the torch start and stop? Does Mach3 control that?

Mach3 is the control program, which runs the CNC machine language (G & M) codes.

An M code number can be located in the program, where needed, to send a signal that activates a relay on or off, which in turn is connected to the plasma torch switch circuit to start or stop the plasma unit.

The machine codes then are telling the torch where to go, how fast, & what to do when it gets there.

Keep asking questions, there is lots of help available from the members here at CNC Zone.

Thanks Weldtutor,
You hold true to your name.
I plan to buy a controller from candcnc.com I trust they should have everything I need to get my machine running...I hope.

Thanks again
