Rastering with LinuxCNC doesn't work as well as it could. Do you have a feel for how frequently the laser power needs to be adjusted? I think that the best way to do rastering would be with a special-purpose raster-generator component which also knows where in an image file it currently is, and has an independent power output to HAL based on the current pixel value. I thing that involving G-code at all is a mistake. I did make a start on making a set of HAL components to do this. But it was purely an academic excercise, and I got bogged-down in trying to make a finite-jerk rastering planner. (un-necessary to make it work). -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
