I made a start on a laser rasterer, and got as far as loading JPEG data into a share-memory area where a HAL realtime component could see it. I then made a start on a simple raster-only motion planner (no G-code) that was going to read out the data and modulate a laser accordingly. Then I got distracted by making the motion-planner jerk-free and zero-lookahead, which was fun, but ultimately didn't get finished, and neither did the rest of the project. (If I actually owned a laser then I might have continued) I am surprised that nobody has mentioned "Koppi's Toy" http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Koppi's_Toy -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Want excitement?
