Hello,

I have built a CNC Plasma Table with Mach3 USB as the controller.

I Have all 3 axis motors working, calibrated, and soft Limits set. It all works good.

My issue is triggering my Plasma torch.

I have a relay wired in. and I can send manual power to it and the Touch will fire.

In Mach3 I can hit the torch button, and m3 on, m5 off, and it will flash, and in the diagnostics page

it flash also.

I have the output pin port 1 and pin 1. On Router page, I have clock wise rotation to pin 1

I have the router relay turned off.

Mill page, I have the THC button on. (i have tried it both ways)

I have watched, read. All that I can find on the internet on wiring and trouble shooting the plasma switch trigger.

I have gone as far as uninstalling and reinstalling Mach3 software, and replacing the Mach3 board and the relay.

  I have since confirmed signal on #1 output pin and at the relay.  but the torch will not fire. again I have taken the trigger 2 wires and connected them and the torch will fire.

 I have replace the relays.

 Am I missing a button or function ?

  would there a good guide on setting up Mach3 for a plasma cutter?

  I am sending screen shoots of a few pages in Mach3 program!

  THANKS for any help or directions!!
