Laser engraver rotary tool

prusaprinters

<p>A very simple rotary attachment for a laser engraver using standard reprap parts.<br/> This uses two NEMA 17 motor wired in parallel. It is cut from 1/4" MDF.</p> <p>The design is simple intentionally so it can be modified and changed to fit your need. I went with two motors so there is no belts or gears or extra stuff making it more complicated.</p> <p>A little trick is if you resize the rollers on the threaded rod (either the printed or cut one) to match the same size as your gear pulley on your Y-Axis then you won't have to modify your steps to run the engraver. Mine was .85" in diameter.</p> <p> <figure class="media"> <oembed url="https://www.youtube.com/watch?v=bCmKmEdohK4"></oembed> </figure> </p> <p>Parts:<br/> 2 NEMA 17 motors<br/> 2 5mm to 8mm couplers<br/> 2 8mm threaded rods about 8 inches long<br/> 4 F60ZZ Flanged bearings<br/> (regular 608 bearings will work just fine but you will need a few extra M8 bolts)<br/> 12 M8 nuts<br/> 1 Wood glue</p> Category: Tools
