Emblaser 1 Geared Laser Mount

thingiverse

Adjusting the height of the laser on the Emblaser 1 can be quite difficult. By default, the mount is a friction fit and must be forced up or down by hand. This works well for the most part, but if trying to cut through a material at the maximum thickness, fine adjustments are difficult due to gantry flex. This design adds a rack gear to the mount, and spur gears to the laser extrusion. This allows the spur gears to be turned by hand to raise and lower the laser height very accurately. A shortened fan mount is included to suit. https://www.youtube.com/watch?v=D2VDYSpouYY This design is not compatible with the standard safety cover. It depresses the micro switch to keep the laser primed as if the standard cover was in place. I will release a modified safety cover in future, although I currently don't use it. 2 x M3x12mm screws are required to attach the gear clips to the laser extrusion. If the parts are printed accurately, they will press against the extrusion enough to stop the clip from sliding, but not prevent the gear from turning.
