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,

Should i Redo the torch calibration?

Joey,

Can this be a grounding issue with the table and unit? Or a lack there of.

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 ...

Joey,


Thanks!

Fires right up when the outputs are set correctly.

Much appreciated, now onto the rest of the setup.
