Hello, I have been building my plasma table for awhile now and have been working on RF shielding issues. I had my machine operating on a Compaq PC with XP. It worked ok except for the HF issues. Computer quit and I got a Dell with XP but I cant get it to operate my machine. I have checked to pins on the parallel port and for some reason its not putting out the propper sygnals to the pins.
Pins,2,6,and 25 have 3.3 volts with program sitting idle.
Pins 10,11,12,13,and 24 have 4.3 volts all other pins have 0 volts. I have assigned pins in motor outputs and tested with meter and I get readings that do not correspond the the control inputs
Help Please
Thanks
