Anyone out there have any old 6000 series controller parts? Specifically the pc board for the #2 parallel port for the plasma portion. I think mine has a intermittent short and will not let the OK to move signal through, this then will not turn on the THC. The machine moves to the first pierce, fires and just sits there burning a hole. I have got it to work occasionally by moving the 25 pin connector back and for in the socket. But now it is non functional, stuck at the first pierce. Mine has a 4 wire set, 8 wire set, and a ribbon cord plugged into the back of the board.
I can get it to move by making the THC ON pin active low. But that cause another set of issues, the torch starts moving before the arc is established leaving uncut portions. Also there is no feedback for voltages so the torch does not move up or down to optimize the cut.
Anyway if anyone could point me in the direction of that board please PM me.
Thanks Much
Mike
