BCN3D+ HD (high Z precision axis)

prusaprinters

<p>With this update your Z axis will be more precise and you will avoid common problems such as Z waving.</p> <p>You will need:</p> <ul> <li>2 x SWZ-063009 precision nuts (I bought them <a href="http://bcndynamics.com/es/product/tuerca-husillo-8x15mm-swz-063009">here</a>)</li> <li>2 x threaded rod 8x1.5mm (lenght 360mm) (I bought them <a href="http://bcndynamics.com/es/product/husillo-8x15mm-l390mm">here</a>)</li> </ul> <p>You will also need to modify your firmware, it's a simple line in Configuration.h but it's important because the new rods have a different pitch than the original ones. So, go to Configuration.h, comment the first as follows:</p> <p>//#define DEFAULT_AXIS_STEPS_PER_UNIT {80.19,80.43,2560,458.3} // BCN3D+ default</p> <p>And add the new line:</p> <p>#define DEFAULT_AXIS_STEPS_PER_UNIT {80.19,80.43,2117.048,458.3} // BCN3D+ HD (precision Z rods from IGUS with 1.5 thread pitch). Theoretically it should be 2560/1.5 but 2117.048 was fine calibrated and outputs better results, I recommend recalibrate it for your specific printer</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>BCN3D+</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>No</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.3mm</p></div> <p><strong>Infill:</strong></p> <p>20%</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>You can also print them at 0.2mm but original BCN3D+ printer parts are done at this resolution.</p></div> </p></p> Category: 3D Printer Parts
