It turned out to be a bad ribbon cable that attached the port inside the computer to the BOB. Those PIC connections are hard to find. Thanks to Tweakie for support.

I don't understand what you mean. Those pin combinations correspond to the step and direction pins of my breakout board. Motor 0 is the X axis, Motor 1 is the Z axis and Motor 2 is the Y axis. Granted the order is strange - XZY instead of XYZ but this definition has been working OK  for years

It says THC300 as the profile which was what I uploaded only having changed the name so it would upload.
I have tried reloading Mach3 and the problem follows pins 6 and 7.  Whatever is attached to them doesn't work. I have swapped cables and even the breakout board but pins 6 and 7 fail to work. I suppose it could be bad pins on the parallel card. I'll replace that and see.

I don't know how that might happen. There was only one file named THC300.xml on the computer. I had to rename it before I could upload it because it said there was already a file named THC300.xml on the system. I am not very literate with all the files and programs. I use the programs to make parts so I need more coaching than the average poster.

Interesting. Here is an image of the Ports and Pins page. You can see clearly that Z axis is pins 6 and 7,

My DIY gantry is being uncooperative with the Z axis control. I had added a torch height controller a few months back so the control of the Z axis was now being done by the THC. From a physical standpoint the only change was the step and direction commands came from the THC unit instead of from MACH3. SO the THC decided to become uncooperative  and I removed it from the system.
Hooked the cable from the BOB back to the driver board and nothing from the Z axis controls.
Switched the cable from the Y axis to t he Z axis driver board and it drives the Z axis well.. Switching the cables back and changing the pin assignments in Ports and Pins and the "failure" follows the pins. They are enabled in Ports and Pins (6 and 7). I am certain that there is somewhere the pins are disabled but I am at a loss as to where.

I'm using Mach3, WinXP

I was having similar problems. If you haven't already download the Parallel Port monitor from
http://www.geekhideout.com/parmon.shtml. Make sure that the port address corresponds to the right port.
In my case, parmon showed that the limit switch signals and Estop were on address 0x379 while the port settings in Mach3 showed the standard 0x378.
The solution was to enable the secondary port with an address of 0x379 and change the port number in the setup.

Confirmed - adding a ground to the tip allows for reliable arc and no computer freeze.

I think I may have found the answer in this thread -

I'll let you know after I add the ground wire to the tip.
