I used img2gcode. Set the laser on to M106 S and the off to M107. Not really any other settings.
A pen drawing works, then I tried a vector engrave with the laser works and it works. It moves by manual control no problem. It is just any raster engraving file I attempt to run.
Did you attempt to run the gcode I posted further up the thread? I did not work for you either? Same errors?
Is it an issue that the files are HUGE?
Could some one post a sample gcode of a raster that works for me to try?
