<p>Remix of (<a href="https://www.thingiverse.com/thing:5404993">https://www.thingiverse.com/thing:5404993</a>)</p> <p>I remixed this to use the stock v6 cooling and lighten the design, yet extremely rigid. I have also added mounting for the Superfly Extruder (you can mount the Superfly in 2 diffrent positions, angled or horizontal). You can use the stock nema 17 extruder motor with the Superfly extruder.</p> <p>All you need is a $15 BMG Clone, and a few M3 screws/nuts/washers</p> <p>Superfly Extuder (<a href="https://www.thingiverse.com/thing:4914090">https://www.thingiverse.com/thing:4914090</a>)</p> <p>MRF Sailfin Extruder (<a href="https://www.thingiverse.com/thing:5149028">https://www.thingiverse.com/thing:5149028</a>)</p> <p>Claw fan duct (thanks to cjlaw1611 - <a href="https://cults3d.com/de/benutzer/cjlaw1611">https://cults3d.com/de/benutzer/cjlaw1611</a> for the design)</p> <p>It is designed for a V6 hotend (clone) but might work for others as the fan holder is height adjustable.</p> <p>*<strong>Screw list:</strong>*</p> <p>(This list is exact fit)</p> <p>13 - M3*8</p> <p>4 - M3 nuts</p> <p>2 - M3* 30/40 that come with BMG extruder (or clone BMG)</p> <p>2 - M3/nuts (from stock radial fan)</p> <p>BLTouch - use the M3 screws and nuts that came with it (M3*8)</p> <p>Superfly Extruder (6 M3 Washers)</p> <p>Print head back to X-axis: 4 M3x8</p> <p>Print head front to back: 2*M3x30 and 2 M3 nuts</p> <p>Fan holder to print head front: 2* M3x8, 2 M3 nuts</p> <p>MRF DualDrive Extruder Sailfin to print head: 2*M3x8</p> <p>Superfly Extruder to print head (2* M3x8, 6 M3 Washers or just use shorter M3's M3*4 or 6)</p> <p>Claw fan duct to fan holder: 2* M3x8</p> <p>Endstop trigger to print head back: 1*M3x8</p> <p>5015 radial fan to fan holder: 2* M3x18 or M3x20 (use stock ones from KP3S)</p> <p>BLTouch to print head back: 2* M3x8 (use what came with the BLTouch)</p> <p>*<strong>Warning</strong>*</p> <p>Using dual gear extruder (Superfly or Sailfin)</p> <p>The motor will extrude in reverse (actually pulling filament out)</p> <p>So using these dual gear extruders you will need to reverse the direction of the of the stepper motor.</p> <p>I have included a pic of what wires to swap (this is an easy method if you are using stock KP3S firmware) or if you just dont want to compile marlin or klipper. I have included a pic so you can see what wires need to be swapped at the connector of the extruder stepper.</p> <p>If you do not want to swap the wires, you will need to compile marlin and set the following line in configuration.h:</p> <p>#define INVERT_E0_DIR true to #define INVERT_E0_DIR false</p> <p>in the configuration.h</p> <p>If using Klipper you will need to remove the ! on the extruder pin when compiling Klipper Firmware</p> <p>*<strong>BLTouch offset (nozzle to BLTouch tip):</strong>*</p> <p>X: +25,6 mm</p> <p>Y: +10 mm</p> <p>*<strong>Superfly &amp; Sailfin E-Steps</strong>*</p> <p>Start with 844 (my exact esteps were 844.8)</p> <p>easy calculator (<a href="https://www.th3dstudio.com/estep-calculator/">https://www.th3dstudio.com/estep-calculator/</a>)</p> <p>*<strong>Print Settings</strong>*</p> <p>Supports:</p> <p>Yes - only for claw fan</p> <p>Brim - only for claw fan</p> <p>40% infill (gyroid) for all parts.</p> <p>*<strong>Notes:</strong>*</p> <p>Everything be printed with PLA(+) depending on how you are using the printer and whether it is enclosed or not.</p> <p>*<strong>Post-Printing</strong>*</p> <p>Tolerances for the mounting holes of the extruders are pretty tight for M3, you might need to use a 3/32 or 7/64 drill bit in the holes to loosen them up a bit. This has been done so you can mount directly into the printhead. Same with the claw fan to the bracket.</p> <p>*<strong>If you want to print Really fast --- &gt; Klipper Configs and Firmware:</strong>* <a href="https://www.thingiverse.com/thing:5420537">https://www.thingiverse.com/thing:5420537</a></p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Kingroon KP3S</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>.2</p></div> <p><strong>Infill:</strong></p> <p>40% Gyroid</p> <p><strong>Filament:</strong></p> Doesn't matter PLA+ <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Tree supports and brim are only needed for the Claw Fan.<br/> Print all parts in the orientation of the stl <h3>Post-Printing</h3> <p>Some hole tolerances are very tight depending on your filament shrinkage.</p> <p>You might need to use a 3/32 or 7/64 drill bit (by hand) to loosen the holes for the M3 screws.</p> <p>They should be a tight fight as some parts such as the extruders don't use capture nuts, and screw directly into the carrier head.</p> </p></div></p> Category: 3D Printer Extruders
