prusaprinters

<p>This is concept of cheap 3D scanner with lidar ( <a href="http://www.benewake.com/en/tfmini.html">http://www.benewake.com/en/tfmini.html</a> ).<br/> I use Arduino Nano with CNC shield + A4988 driver for stepper motor.<br/> Scanner write position (x,y,z) to SD card.</p> <p>buttons for home H(orizontal), for home V(ertical), scan and stop(not working yet).</p> <p>v1</p> <p> <figure class="media"> <oembed url="https://www.youtube.com/watch?v=Q2yE-5H5z7s&amp;feature=youtu.be"></oembed> </figure> </p> <p>v2<br/> <figure class="media"> <oembed url="https://www.youtube.com/watch?v=YJjjC-yB83Y"></oembed> </figure> </p> <p>for now:<br/> this is first test build.<br/> NOT work microstep, so 1 step is 1,8° (not good for scanner-working on)<br/> lidar accuracy is not acceptable - see video</p> <p>UPDATE:<br/> modify for change lidar or ultrasonic senor.<br/> enabled multistep on driver(shield has wrong wiring...)<br/> In archive scannerv2.zip are all files</p> <p>more info. <a href="http://mochr.cz/3d-scanner/">http://mochr.cz/3d-scanner/</a></p> <h3>Print instructions</h3><p>Unassociated tags: cloud points, cnc shield, stepper motor, ultra sonic<br/> Category: DIY</p>
