According to the Fletcher site, a 3100 can cut ACM up to 2 millimeters thick. Here's my question. Is it possible to cut 4 ml board, by doing one cut one each side, so they 'meet in the middle'? Or not? I'm guessing not, but figured it's worth asking. We've never worked with it before, and the piece will be around 43 x 59. Trying to figure out whether to get a big one and try cutting, or just get it pre-cut.
