prusaprinters

<p>This is an "airtight", compact and easy to fill filament buffer for your MMU2.0 setup. It uses a check valve for the filament so it is not pushed back on to the spools. Watch the video below on how it works.</p> <h3>Print instructions</h3><p><strong>How to fill the buffer</strong></p> <figure class="media"> <oembed url="https://www.youtube.com/embed/2d24AwWaWys"></oembed> </figure> <p><strong>Before you start</strong><br/> This is still a work in progress. Before you print, check for the latest files and instructions. See change log at the bottom.<br/> The buffer does not fix any problems you might have with the MMU2 unit. Please make sure to have your MMU2 running fine before installing the buffer.<br/> If your MMU2 works you will like the buffer though.</p> <p>Find all the information here:<br/> <a href="https://www.printschnitzel.at/post/introducing-the-airtight-easy-to-fill-filament-buffer">Introduction</a><br/> <a href="https://www.printschnitzel.at/post/how-to-make-it-1">HowTo</a></p> <p><strong>changelog</strong></p> <p>2019-07-09: changed <em>Buffer3_part2-buffer_part_2-18.stl</em> more clearance for the filament 2mm _&gt; 2.2mm<br/> 2019-07-09: changed <em>Buffer3_part1-buffer_part_1-18.stl</em> more clearance for the filament 2mm _&gt; 2.2mm<br/> 2019-07-09: changed <em>Buffer3_part_1_with_logo_mod-18.amf</em> more clearance for the filament 2mm _&gt; 2.2mm<br/> 2019-06-29:changed <em>Klemmung_1-ptfe_clamping_1_17</em> increased hole size for easier installation of ptfe tubes<br/> 2019-06-26: changed <em>Buffer3_part1-buffer_part_1-17.stl</em> by increasing the pre-bending of the filament<br/> 2019-06-26: changed <em>Buffer3_part_1_with_logo_mod-17.zip.amf</em><br/> 2019-06-26: changed <em>Logo_mod-logo_mod-17.stl</em> so it takes less retraction moves<br/> 2019-06-25: changed <em>Logo_mod-logo_mod-17.stl</em><br/> 2019-06-25: changed <em>Buffer3_part_1_with_logo_mod-17.zip.amf</em><br/> 2019-06-24: changed <em>Logo_mod-logo_mod-17.stl</em></p> <h3>references</h3> <p>Thank you prusa for interviewing me at [Maker Fair Vienna] <figure class="media"> <oembed url="https://www.youtube.com/embed/bELUucZeVWg?start=213"></oembed> </figure> </p>
