DIY TL smoother box

prusaprinters

<p>Ordered some tl smoothers to test from Aliexpress, but while waiting for them to arrive, I thought that why not build one as I have the proper diodes. As it seemed to work for what I wanted (fixing DRV8825 jerky slow movements), I decided to make a box for it.</p> <p>The circuit I used is from here: <a href="http://cabristor.blogspot.com/2015/02/drv8825-missing-steps.html?m=1">http://cabristor.blogspot.com/2015/02/drv8825-missing-steps.html?m=1</a></p> <p>You'll need following items to build this:</p> <ul> <li>4 pin header</li> <li>8 1N5404 diodes</li> <li>some wire</li> <li>4 M3 6mm screws</li> </ul> <p>I printed mine with PolyMax PLA as I had it loaded on my printer and it seems to work fine. The diodes do get bit hot, so if there's no air circulation, it might be a good idea to use PETG or ABS.</p> <p>OpenSCAD source is here: <a href="https://github.com/spegelius/3DModels/tree/master/TL_smoother">https://github.com/spegelius/3DModels/tree/master/TL_smoother</a></p> Category: 3D Printer Accessories
