E3D/Titan direct drive for X5SA Pro

prusaprinters

<p>Had to quickly adapt my X5SA to a direct drive. This uses an:<br/> • E3D hotend (1.75 direct drive or universal).<br/> • The Titan extruder<br/> • A pancake stepper motor (<a href="https://www.omc-stepperonline.com/nema-17-stepper-motor/nema-17-bipolar-1-8deg-13ncm-18-4oz-in-0-7a-2-9v-42x42x25mm-4-wires.html">https://www.omc-stepperonline.com/nema-17-stepper-motor/nema-17-bipolar-1-8deg-13ncm-18-4oz-in-0-7a-2-9v-42x42x25mm-4-wires.html</a>)<br/> • 3 x m3 square nuts (e.g., as per Prusa)<br/> • Some normal m3 nuts and bolts</p> <p>Bolt the carriage onto the existing metal plate using a pair of M3 botls with nyloc nuts, and a pair of shorter ones (8mm maybe) into the holes for the old hotend.</p> <p>Feed the wires for the x-axis limit and the level sensor through the cable channel and install the motor carriage and titan on top.</p> <p>X-axis shouldn't change, but the nozzle will be around 18mm further forward compared to the old Mk8. I've included a Y-axis limit arm that should recover that distance, but watch out for clearance at the back of the machine.</p> <p>There's a fan plate that will use the existing axial fan, but it should be easy to adapt for other fan types.</p> <p>In addition there is an adaptor to mount the filament sensor to the V-slot, and a modified motor mount for the Y-axis to raise that motor slightly.</p> <p>I used the heater cartridge and thermistor from the Mk8 nozzle as I had an older V6 variant. If you use an E3D thermistor you may have to tweak your firmware.</p> <h3>Print instructions</h3><p>Support from buildplate for the nut pockets.</p>
