Can this machine cut a new grid? Absolutely. Does it require repositioning the stock because the parts are longer than cut area? Yes. If you have watched Keith Fenner’s YouTube channel, you know he is quite skilled at plasma cam and a skilled machinist, but he says that a new grid kit is cheap enough from plasmacam that he buys them rather than cuts them. I’d suggest getting a quote from plasmacam, including shipping, and compare against the price of the raw steel required. I’m guessing there will be at least a couple 3x5 scraps left over, because I don’t think two pieces can nest end to end out of a 4x8 sheet. Maybe efficiency goes up if you can get a 4x10 cut in half.
