Magnetic Fume System for xTool M1 Laser Cutter

<p>I made this magnetic fume extraction setup for my <a href="https://www.xtool.com/products/pre-order-xtool-m1-worlds-first-desktop-hybrid-laser-blade-cutting-machine">xTool M1 </a>hybrid laser and blade cutting machine. &nbsp;This makes it easier to move the machine around, and allows me to add a second fume extraction fan. &nbsp;I still wasn't satisfied with the strength of this spare 70mm x 15mm fan I had laying around, so I might make another version of the window piece that uses a larger stronger fan to extract even more smoke. &nbsp;Feel free to comment with any requests or suggestions.&nbsp;</p><p>The piece that attaches to the machine uses the original thumbscrews to connect to the M1. &nbsp;It only has 3 magnets so that it doesn't stick up above the machine, but trust me 3 magnets is more than enough to hold these in place. &nbsp;</p><p><strong>Magnets</strong></p><p>The pair of parts that attach to the machine needs 3 magnets per piece (6 total), and the other end uses up to 4 magnets per piece (8 total). &nbsp;Uses 60mm x 10mm x 3mm bar magnets from Amazon: &nbsp;“<a href="https://www.amazon.com/gp/product/B07DFZH4WT">LOVIMAG Powerful Neodymium Bar Magnets, Rare Earth Metal Neodymium Magnet - 60 x 10 x 3 mm, Pack of 24</a>” (Need 14 magnets total among the 4 pieces)</p><p>If you're using the “Exposed Magnets” file you'll need to glue them in. &nbsp;I've used super glue with magnets on PLA with some success before, but 2-part epoxy works much better. &nbsp;You also might want to cover the magnet with electrical tape or some other kind of tape just so there isn't quite as much pulling force between the two magnets. &nbsp;</p><p><strong>Slicing Tips</strong></p><p>For the embedded magnet versions you'll need to pause the print immediately before the layer that it bridges over the magnet hole, insert the magnets, then resume the print. &nbsp;The easiest way to do this is to use<a href="https://help.prusa3d.com/article/color-change_1687"> Prusaslicer and put in a color change</a> at that layer. &nbsp;</p><p>The first time I tried to print a file with embedded magnets the slicer tried to bridge the gap longways, which doesn't work well because the filament doesn't stick to the magnets and bunched up and made a blob. &nbsp;If you're using Prusaslicer go to <i>Print Settings, Infill, </i>and change <i>Bridging angle</i> to 45 degrees. &nbsp;This is an “Advanced” setting so in the top right make sure <i>Advanced</i> or <i>Expert</i> is selected.&nbsp;</p>
