Have new plasmacam with DesignEdge software, cannot get torch to fire

[Cfhaddox]

I have a hyperthermia 65 with machine interface cable with voltage divider board, I have also purchased cable from hypertherm to connect table to cutter. Have set 21.1:1 instead of factory 50:1. My issue is I cannot get my plasma to fire when I try to cut, any suggestions out there. I have auto height control

Do you see an error on your Hypertherm LCD when trying to fire. Something like 0-20 or 0-52 etc

Are you using a hand torch or machine torch? The machine interface is designed only to work with the machine torch - it will not control the trigger circuit for the hand torch.

If you are using the hand torch, you'll need to either get and switch to a machine torch or modify the wiring for the trigger circuit as shown in the video manual (splice inline with the purple trigger wire and zip tie the trigger on).
