Prusa i3 laser pointer mount for Laser 303

thingiverse

I use the thing by attaching it to the extruder carriage in place of the fan, thus extruder and laser are both accessible at any time, no swapping required. Laser 303 which I use is only about 100mW in power, so it can engrave only dark surfaces of burnable materials. The hole on the front is for M3 bolt to hold the laser in place. For engraving I use inkscape with "J Tech Photonics Laser Tool" extension. To engrave in pseudo-raster style, I use my own crude software (image2lines) to convert image into lots of straight lines, so that inkscape laser extension can generate accurate gcode from them. You are free to use and modify this software however you want. Important note: Linux versions of image2line are not tested and might not work at all. I added 7805 to drive the laser directly from fan port of the printer motherboard. Commands M106 and M107 are used to switch laser on/off, this has to be set in the inkscape laser extension.
