Hello,
I am using a Miller Spectrum 2050 plasma cutter with a Fireball Comet CNC router, but no plasma arc is being produced. Gas is still flowing, so that is not the cause of the problem. I discovered the Miller's CNC wire is broken, so I am trying to replace it. Problem is I do not think the Miller Spectrum 2050 manual says anything about the CNC controller. I do not know if the CNC controller also needs to be replaced. Any tips on how to test the Miller Spectrum 2050's CNC controller circuit board?
