ohmic not detected

[Jon Vance]

Updated the firmware today, and now the ohmic sensing will not detect. Any suggestions would be great. Thanks

If you are just jogging the torch down to the material you will need to first turn the relay on, under Machine Settings and Advanced Tab set Relay Output to On, this way you can test the ohmic circuit. If when the relay is on you can use a test wire to go between the orange wire to the VFC ground screw and work your way back from there to the material you will see where you are getting the disconnect. Material needs to have continuity to the VFC ground screw.

Got the ohmic sensing to work. Now when I go to run a cut, the plasma does not fire at all. Does anybody know what setting that we might have set right on our computer.

Thanks,

Make sure you are in Active Run and not Dru Run. Make sure the torch start and stop wires are plugged into port 1 on the back of the Accumove box, if in doubt you can jump across these two wires to see if it trigger the plasma to strike an arc.
