while checking things out, i stumbled across a program called meshcam. after reading the propaganda, i decided to give the 15 day trial a go. happy day! it seems to work and play well with my sketchup designs, works out ok on the cnc simulator that i have on the laptop, and today started the real test, running it on the cnc itself. so far so good, taking a bit more time than i expected, but that can be tweaked here and there. i'll post pics of the test items as they are finished. no real wood is being harmed, only some odd mdf scraps that are laying about.
