Joey, Thanks for the help. And patience.

I Will redo the Torch calibration,

To confirm from the posts,I can gather from your replies and help that the Plots look good, and the grounding issues are fixed and I'm good to do further cutting without damage?

Thanks again, it is appreciated.

The 4 inch line cuts is done on .0625 steel clean,


the oringial calibration was done on .25 steel before the grounding issues,

(1% unsure because its not working) Attached is photos of the cabinet, Its a doozy, after reviewing the schematics I see that I am missing a wire from the ground to the common on the main power supply that powers the acorn board. ...

I have read the hypertherm bulletin on grounding. And have work to do.

Hello, I am having issues with my Torch height while cutting. If I put a large sheet of steel in with differences in height from the shearing or having some waves from storage maybe +- .125 of an inch. the torch is scraping or running into the material. it does not change the z height as it cuts to ...

Joey,
