Configuring Plasmac - a complete THC/plasma config for any hardware

Just looked at your output. You just need to replace the question marks in the hal file John wrote for you with the real pin number. Either use Halshow or use the 7i76e manual. The manual is a bit confusing as the hardware pins are numbered from 1, but the output pins start at INPUT0.

So if you connect a wire to TB6 Pin 5, it will be INPUT4. In halshow, it will be hm2_7i76e.0.7i76.0.0.input-04. You can always check a pin by jumpering field power to it and watching it change state in halshow.

also further to this, I have kept a master list of the pins I use in Google Drive. I always update this table before doing the actual wiring

But how does it know your talking about TB6 and not any of the other TB# inputs/outputs.

Because page 11 of the 7i76e Manual says that Input 4 is on TB6 pin 5.

Because all the inputs are consecutively numbered.

You connected wires to your 7i76ED, start with the connector and pin number and then look up logical number, usually X-1.

LinuxCNC will not start until you either get pin numbers right or comment out the lines. You can run Halshow from the command line to find the pins. The instructions are in the documents. Read all of the hal configuration documentation.

Looks like I didn't get some joint max speeds and accelerations, just add the same values as the axis except for Z which will be 1/2.

If you connect a pin to field power, the input will change state. So why don't you connect a wire to +ve Field power, open up halshow, watch a bunch of input pins and experiment by prodding them with the wire? If you do this, prod the wire connector not the screw on top which may not have a connection if there is no wire present.

You will also see in Halshow that for each pin, there is another ending in -NOT. These are for convenience as they will show the opposite of the actual pin state. Sometimes you will use them (eg. When you have a normally closed circuit).
