Metal will not cut

My design will not cut all the way through. Not sure if it is a problem with my tool on fusion or my machine. The metal is 3/8 inch thick. Let me know if anyone knows why this is happening. Thanks.

You will need to tell us more if you want help.
Do your home work and list everything you can about your set up and your cutting settings EVERYTHING you can think of


We’ll have to get your settings to know more or you could post your G-Code. But I can speculate a little bit with the limited information.

Work clamp not on the material

Bad or improper consumables

Wrong amperage setting.

Too fast for amperage setting.

Incorrect cut height.

We should be able to whittle down this list once we have a few more pieces of the puzzle.


Hard to tell for sure, but it looks like your pierce cuts went all the way through, so maybe just slow the cut rate.
