Just like the title says. I have X4, no interest in upgrading, I am using an old small desktop 4 axis cnc machine. Going to be doing mostly small 3d wax seal stuff. I got this software with the hasp when My ship decommissioned and they told me to "dispose of it", well my wife has a need for me to relearn how to use this software and make her little machining center make her some money.
