I am considering a small Chinese 40W laser cutter "eBay Special." The cutting dimensions are well documented (12" x 8" or 300mm x 200mm, BTW, which is it!), but I wanted to know if anyone knew the dimensions of the material that can go into the machine, even if cutting area is smaller. For example, could I put a 15"x10" board in, even though I can only cut an interior 12"x8" rectangle in it? Thanks for the help.
