Plasma uses M03 for torch on and M05 for torch off. In MACH you "map" certain M commands to certain MACH ouputs (set in the Ports 7 Pins/Spindle Setup tab).

Once you map M03 to an Output (say Output 1) you then have to map in the ports and pins which PHYSICAL output (port and pin) it actually talks to. On a conventional BOB and parallel port the outputs available for relay or ON/OFF control are 1, 14 , 16 and 17. Those a re actual physical pins on the parallel port so you use a BOB to physically access those pins. A typical set may have M03 and M05 mapped to output1 and output1 is mapped to port1 1 pin 14. The polarity of that output when it's activeis defined in the Active Low column (you can make it go high for active or low for active. The parallel port pins have little current drive capability so typically you need some form of buffers to interface to increase the drive.

Since everything in MACH is defined by the "Profile" (XML) your settings when changed get stored in the profile.
