  10. Safety Jandals retreaded on the laser cutting machine

    Lee is right that you should plan on using a lighter motor on the x axis, say a nema 17 which is in every 3d printer.

    Instead of doing a coutersink I do a counterbore using the laser. It can be done in raster or vector mode. The acrylic is already in the laser so its no trouble and means less handling.
