There is no bed reference on Setworks only Accuset has bed reference. This means every last cut will be off, maybe a little maybe a lot it depends where you start. Once you get some time with the scale you will know about where to start to come up close. The scale kerf is set at 1/8 " and the Simple setworks will be fine tuned closer. Accuset will figure out to .001 and give you bed reference there is talk of making Accuset available for Setworks owners but I have not seen it yet.
Hope this helps.
