i am fairly new to the cad/cam world and have a few questions if somebody wouldn't mind helping out. i have been seeing alot of photo to engraving articles out there lately. i understand that the photo will have to be scanned into some type of software and then converted to g-code eventually. my question is this: what software, or packages are necessary to perform this operation? how does this work, as in: scan to what type of file, convert to what type of file and then .... eventually load and run on a cnc machine?
there seems to be, in my mind anyway, a large cloud that the photo goes into and the engraving pops out the other side. could someone put this in laymans terms, kind of an engraving for dummies format?
thanks for the help.
