SMuFF - DDE (Orbiter) mount with integrated Filament-Cutter for Ender-3

prusaprinters

<h3>Yet another DDE variation for the SMuFF...</h3> <p>This one utilizes the Orbiter Direct Drive Extruder V1.5.</p> <p>The most significant difference to the previous published BIQU-H2 version is, that the Filament-Cutter sits below the extruder and hence, the SMuFF isn't forced to purge the filament in the extruder in order to release the 2nd endstop switch.</p> <p>Although this model is meant to fit the standard Ender-3 extruder, I've replaced the fan shroud with a smaller one that needs a 30 mm fan but also comes in a more compact size and offers the option to mount a BL-Touch or Tiny-Touch to it, as well as a 50x15 blower fan for a more sophisticated part cooling.</p> <p>A decent BL-Touch bracket is included, the Tiny-Touch mounts without a bracket directly.</p> <p>The STEP file is included, so you're able to adopt this design to your specific needs but also to examine which part goes where.</p> <h3>BOM</h3> <p>To build this you'll need:</p> <ul> <li>an Orbiter DDE V1.5</li> <li>up to 15 threaded inserts M3 x5.7mm</li> <li>a 30 mm fan (24V)</li> <li>a 50 x 15 mm blower fan (24V, part cooling)</li> <li>a couple of M3 screws in various length (8mm, 10mm, 16mm and 20mm)</li> <li>a couple of self tapping screws (2.2 x 6.5 mm, 2.2 x 9.5 mm, 2.9 x 6.5 mm)</li> <li>a micro switch (12.8 x 6.5 x 5.8mm)</li> <li>a compression spring (5.5 x 20mm, 0.5-0.6 mm wire diameter)</li> <li>a cutter blade</li> <li>a standard size Servo (i.e. AMEWI)</li> <li>a couple of zip-ties</li> <li>a couple of wires</li> </ul> <h3>Please Notice</h3> <p>The Filament-Cutter uses the same components as the ones I've published before. Hence, if you need to know how it works, visit the <a href="https://sites.google.com/view/the-smuff/work-in-progress?authuser=0">SMuFF website</a> for more articles on this item.</p> <p>The mounting holes for the blower fan are supposed to fit the standard Ender-3 blower fan.</p> <p>Also, in order to run this DDE on the SMuFF, it'll need an firmware update to version 2.32.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>ZEvolution</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>Yes</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.2</p></div> <p><strong>Infill:</strong></p> <p>20-25%</p> <p><strong>Filament:</strong></p> Any Any <p>Any</p> </p></p> Category: 3D Printer Extruders
