Crossfire pro z axis forcing tip into metal during cut

CrossFire ® Troubleshooting
1

I have been using the machine for about a year, it gets used for a couple days then sits for a couple months. This time using the machine, it will lower and find the metal, raise back up then start cutting. then
it will drive the torch into the metal and keep pushing the whole time while the table is trying to cut.
z axis limit switch is clean and working properly
cable connections are clean and tight
cables are routed away from plas cutter cableing
downloaded new version of software

What kind of voltage is it reading when doing this? Are you using smart voltage?

This is what is listed in the Langmuir Troubleshooting guide for THC:

Torch Plunges Down into Material

When the plasma torch slows down in speed, such as around tight corners or arcs, this causes the voltage to instantaneously increase and the THC module will move the torch downward to compensate. FireControl and LS-THC have several features and settings that help to prevent the torch from plunging down into the material during normal operation. If you are still experiencing this issue, the below steps can help to prevent this issue from occurring.
