Everything has been running fine for the most part, but today when attempting to make a cut the torch head will go down to sense the work piece, lift up to the pierce height and initiate the cut but once the torch fires it raises up even higher to about 3/8 above work piece instead of going down to pierce. Just started happening out of no where.
Copy and paste the first 10-15 lines of code here. This is usually caused by an error in entering the pierce/cut heights in the CAM setup.

Could you post maybe the first 25 lines of code.
You posted just enough code did not show the cut height.

Change your cut height to .04 and this should correct your issue.
It’s trying to reach that .4 which is a little bigger than three eighths. It is doing what it’s told to do.
Post back and let us know if that works

This is the easiest mistake to make when setting up the post process values…One forgets or transposes the “0” when entering. I have done it multiple times - Pierce height .15, cut height .60. Pierces just fine then raises up and trashes the nozzle and the part.
Definitely one of the most common errors.
The Decimal Point Transposition Error.

Especially for Canadians, since the ALL use the metric system and the conversion is confusing to them
