Welcome to the forum.

Do a small test design, create the GCode file and cut and paste the text here. That usually provides a clue.

After you’ve posted a few times you’ll be able to do file uploads.

Your pierce height is set at .8". It should be .08" if you want that as a pierce height.

Somewhat unrelated, your springback and backlash is probably excessive at .04"

Thank you don’t know how I missed that I will edit it on fusion , and give it a try , thanks , as for spring back I have never ask it what would be good ball park to start at ?

Backlash accounts for backlash in the lead screw. My testing showed that there was basically no backlash in a relatively new assembly. Springback accounts for the metal flexing when the Torch presses on it. 1/8" and up usually doesn’t flex from the Torch pressing on it.

For anything 1/8 and up, I would set that at zero. You can pause during a cut and measure the actual torch height.
