I am just about convinced I need to spend over 12,000 for a tool which I have no idea of how to use other than some vauge idea I need it to increase productivity of our small shop, since I will be using profits to purchase it I would like to continue making profits to pay myself back. Anyway I have tried to get through the Shopbot web site a trial version of the Partworks and partworks3D software, but all I get from Aspire is the opportunity to try add on programs which will add to the initial cost. Am I missing somthing? Please let me know what you can. I really screwed up my left arm 2 years ago and it seems a PRS 48-96 would help me with a lot of things I used to (and still do) by hand.
