Trying to cut some motor mounts consisting of 3 small and one medium sized piece. The three smalls cut fine, but on the larger piece it stops penetrating the metal about 2/3's through a large inside arc. Tried it twice and it happened at the exact same point both times so I assumed it was some sort of setting but I can't figure out what. Right after I cut some larger pieces but without any large arcs and it cut just fine. Not really sure what setting to play with though as it cuts perfectly right up until it doesn't. I thought I recall a setting that turns off THC control in curves but that was on a differant machine a few years ago now. I'm using Mach3 with a Proma THC150 and a Gecko G540 for the controller if it matters.

Could be a bad nozzle in your torch. If you rotate the nozzle in the torcha dn cut again and see the point at which the plasma stopped penetrating move to another location on the circle thats the problem. Replace your consumables and be sure your air is clean and dry.
