I have my setting in plasmac set at 400 milliseconds.

It doesn't make any sense to me.

Does your relay have a light to show it is doing something? (although the pulse is probably a bit quick)

Exact same behavior. Ill check the relay.

Front and back

Must be something with my plasma then. Is all you changed was the torch on time?

What happens at 999?

Phill,

Relay turns on when it should but Plasma not.

Do you have a replacement relay, i think some solid state relays only indicate that they have an input.

Yes, thats all I played with. the 45XP manual says to dimple at 50 ms so we are on the right track I think but the time delay between firing the torch and the arc starting is likely quite variable between cuts so I think the count down needs to happen after the THCAD voltage confirms we are > 0 volts. Then the plasma won't know we tricked it!.

Ok tried 999 and G4 P10, works

999 G4 P3 works but the P10 created a better mark.

Stefan will have a few spare when a THCAD-5 turns up for him. I will say I had to rethink my Ohmic power supply sensing trigger. I moved it from the ohmic enable to spindle.0.on so it was on all the time just for fun but when we started using spindle.2.on, it was a problem! It now turns on with the machine.

And yes changing the connections.hal file was the final thing I needed to do.
