The VIM box is the same. You have the wires in the right place on the VIM.
The torch on/off wires still need to be plugged in to the control box to fire the torch. They don’t have to be wired to the CNC port, but that’s the easiest way. You could find the trigger wires inside the plasma cutter and wire directly to them. That won’t have anything to do with the voltage reading.
Did you connect the raw voltage to the lugs directly behind the clamp and the Torch? Red to the clamp and black to the torch.
If the work clamp is on the metal and the torch is within 1/8" of the metal it will fire and start cutting, Make sure you have 65 to 70 psi of air pressure. Did you try turning off THC and try to cut? Does it cut with the hand torch not hooked to the table?
If you have a volt meter, unplug the wires from the little black box. Put the positive lead from the meter (red) to the red wire going into the plasma cutter, then the black meter wire to the black wire that goes into the plasma cutter. Fire the torch and make a cut and watch the meter it should show a positive voltage some were between 150 and 300 dc volts.
It seems that the main thing that has changed here, from the old table to the new table, is the electronics enclosure on the table. Look at the wires on the back of the THC connection port at the front of the control box. Are both wires connected? Follow them back to the main board. Are they plugged into the board?
