Hello all

Something stange hapened today, went out to the shop to do some cutting but my machine torch wont fire. Has been working flawlesly for a couple of years so is not related to some sort of set up issue.

Anyways I pluged in the hand torch I have, it fires when the trigers pulled but not when comanded by the CNC. I have a seperate start switch that plugs into the machine interface and it wont cause the torch to fire either.

So dowloaded the Hypertherm service manual and did there plasma start test #8
( involves putting a jumper across the red & white on the machine interface , J19 ), and what do you know the machine torch fires.

Man this confuses me, I'm taking the machine into the dealer on Monday but thought I'd see if anyone out there has had this happen.
