plasmac message error

if I connect pin11 to gnd the UP indicator on the qtplasmac interface should light up

No, pin 11 should be connected to plasmac.move-up. The up LED is connected to plasmac.led-up which can only be on if THC is active and and up signal is present on pin 11. 

just to do a test

hello
I finally replaced the computer, new parallel port and the card db25
I did a test with the hal show the lights change state, I will do a test during the day with the plasma

the lights in the show hall work perfectly, the THC sends the signal to the db25 card, activate the THC but the Z axis does not go up or down
I don't see where the problem comes from?
the problem does not come if I check ignore arcOK?

What voltage does it show on screen while cutting?
What feed rate does it show on screen while cutting?
If the "feed override" set at 100% ?
