MACH3 Plasma help please

[Clive S]

Yes Clive just the one relay, which I can connect to any of the three relay output contacts of the BOB.

I am unclear how Mach treats these outputs. Is it by M code, do I need to write a diddy bit of code or what?

Ok My bob is the PCL6x But is similar. I may be shot for this but I think it would work, In Mach go to ports and pins page then click on tab spindle setup. Then untick the flood/mist relays and enter say 3 in the for the flood relay you could control a relay with flood M8 to turn on and M9 to turn off in your gcode file.

Then under the (output signals tab) then set output #3 to port 1 and pin 16 (you might have to change active low)

You have to set SW3 to on on the BOB.

I stress I am not an expert in Mach3 so can somebody please check this

Edit: it took me so long to answer I did not see Deans post but he for sure will check the above
