Good Day All, I was wondering if any one had built a CNC machine and used Autocad or an Autocad generated file to run it. I know that this is hpgl. Does anyone have any info on such subjects. I am looking at two in some old issues of Microcomputer Journal. What I want to do is write an hpgl file to some eeprom and put it into a pic circuit to control a cnc machine with x,y & Z axis. Basically just plug-n-go programming. Any leads/help would be appreciated. Thanks Guys, Brian
