MACH3 Plasma help please

[AndrewMawson]

Thanks Clive and Jazz for your replies.

A/ My plasma torch is turned ON by an M03 and OFF by an M05

B/ On the BOB if I set DIP switch 5 then my relay pulses on and off with a mark space ratio controlled by the two trim pots.

C/ If I set DIP switch 2 to ON which should change control to LPT Port 1 Pin 14 I can find no M code that controls Pin 14

D/ In the Ports and Pins page of Config there is a line labelled OUTPUT 3 which I have set to Port 1 Pin 14 - this has enabled a switch box marked "Output 3" on screen that previously was not active - I can now click it and change it from Red to Green but other than that it has seemingly no other effect

(In the Spindle page of Config there is an area referring to mist and flood coolant and relay control via M07 and M08 and mapping to output signals in the range of 1-6 and I suspect perhaps it's something to do with the set up here, but I'm not quite getting there at the moment !!!)

Your ongoing hand holding would be appreciated :)
