<p><strong> *UPDATED* Altered the pins to improve fitment, added a channel for the pi ribbon cable. <p><strong>Description</strong></p> <p>Do you have a Wanhao i3, i3 v2/2.1 or i3+?</p> <p>Do you have a Raspberry Pi Zero W and Pi Camera?</p> <p>Do you want to tie it all together in a sleek, compact system for remote monitoring and control?</p> <p>Well here's the project for you!</p> <p><strong>What you'll need:</strong></p> <ol> <li><strong>3 x</strong> M6x5mm Bolts (I use Button Head)</li> <li><strong>3 x</strong> M6 Nuts (Regular or Nyloc)</li> <li><strong>2 x</strong> M3x10mm Bolts (I use Socket Head)</li> <li><strong>2 x</strong> M3 Nuts (Regular or Nyloc)</li> <li><strong>2 x</strong> M3 Washers (7mm Max OD)</li> <li>Printed Parts: <ol> <li><strong>1 x</strong> Arm_Piece_Bolt</li> <li><strong>1 x</strong> Arm_Piece_Nut</li> <li><strong>1 x</strong> i3_Frame_Bracket</li> <li><strong>1 x</strong> Octopi_With_Pi_Cam_Body</li> <li><strong>1 x</strong> Octopi_With_Pi_Cam_Lid</li> <li><strong>1 x</strong> Pi_Zero_W_Case_Holder</li> </ol> </li> <li><strong>1 x</strong> Raspberry Pi Zero W + microSD card (With OctoPi installed)</li> <li><strong>1 x</strong> Camera Module for Raspberry Pi Zero W</li> <li><em>Optional Extras:</em> <ol> <li><em><strong>1 x</strong> DS18B20+ Temperature Sensor</em></li> <li><em><strong>1 x</strong> 4.7k Resistor</em></li> <li><em><strong>3 x</strong> Small Pieces of Heatshrink</em></li> </ol> </li> </ol> <p><strong>Instructions:</strong></p> <ol> <li>Print all parts.</li> <li>Gather needed parts.</li> <li>Install your Raspberry Pi Zero W into the case (<strong>"Octopi_With_Pi_Cam_Body"</strong> + <strong>"Octopi_With_Pi_Cam_Lid"</strong>). The Camera Module ribbon cable should fold under the board, and sit nicely in the square cutout on the underside of <strong>"Octopi_With_Pi_Cam_Body"</strong>.</li> <li><em><strong>*Optional Step Here - See end*</strong></em></li> <li>Slide the <strong>Pi-Cam-Case</strong> assembly into <strong>"Pi_Zero_W_Case_Holder"</strong> - The orientation depends on your bed height, there's a few mm up and down for adjustment here.</li> <li>Using <strong>2 x M3x10</strong> Bolts, Washers and Nuts, attatch <strong>"i3_Frame_Bracket"</strong> to the spare mounting locations for Z-Stop switches (On the opposite side to your actual Z-stop). Again, there is a few holes to choose from here for adjusting the height of your camera.</li> <li>Using <strong>1 x M6x5</strong> Bolt and Nut, attach <strong>"Arm_Piece_Bolt"</strong> to <strong>"i3_Frame_Bracket"</strong>.</li> <li>Using <strong>1 x M6x5</strong> Bolt and Nut, attach <strong>"Arm_Piece_Nut"</strong> to <strong>"Arm_Piece_Bolt"</strong>.</li> <li>Using <strong>1 x M6x5</strong> Bolt and Nut, attach <strong>"Arm_Piece_Bolt"</strong> to the <strong>Pi-Cam-Case-Holder</strong> assembly you completed in <strong>Step 5.</strong></li> <li>Sit back and admire your smart new setup!</li> </ol> <p>The mount is adjustable by loosening/tightening the M6 Bolts, the nuts should be retained in the arms. You can also adjust it in the Z direction by using either of the 4 spare Z-Stop locations, and by sliding the Pi Case up and down inside the Holder.</p> <p><strong>If you need extra length to your arm, simply print off one more of each <strong>"Arm_Piece_Bolt"</strong> and <strong>"Arm_Piece_Nut"</strong>. You will need an extra <strong>2 x M6x5 Bolts and 2 x M6 Nuts .</strong> <p> </p> <p><em><strong>*Optional Step to Monitor Enclosure/Room Temperature*:</strong></em></p> <ol> <li>Solder <strong>Pin 1</strong> of the <strong>DS18B20+</strong> to a piece of wire. Heatshrink over the connection for added strength.</li> <li>Connect this Wire to the <strong>Ground GPIO</strong> Pad/Pin on your Pi Zero W.</li> <li>Solder the <strong>4.7k resistor</strong> between <strong>Pins 2 and 3</strong> on the <strong>DS18B20+</strong>, Heatshrinking over the connections if desired.</li> <li>Connect a length of wire to <strong>Pin 2</strong> of the <strong>DS18B20+</strong>. Heatshrink over the connection for added strength.</li> <li>Connect this wire to the <strong>GPIO4(GPCLK0)</strong> Pad/Pin on your Pi Zero W.</li> <li>Connect a length of wire to <strong>Pin 3</strong> of the <strong>DS18B20+</strong>. Heatshrink over the connection for added strength.</li> <li>Connect this wire to the <strong>3V3 Power</strong> Pad/Pin on your Pi Zero W.</li> <li>Install the "Room Temperature" Plugin by Frederic Moutin, detailed here: (<a href="https://github.com/l00ma/OctoPrint-roomTemp">https://github.com/l00ma/OctoPrint-roomTemp</a>).</li> <li>Run the three wires through the three channels in the Pi Zero W case, and install your sensor in a location of your choosing.</li> </ol> <p> </p> <p><strong>Don't Forget:</strong></p> <ul> <li><strong>You may need to flip your PiCam Stream. Do this from inside the OctoPrint Web UI.</strong></li> </ul> <p> </p> <p><em>Links:</em></p> <ul> <li><a href="https://github.com/l00ma/OctoPrint-roomTemp">https://github.com/l00ma/OctoPrint-roomTemp</a> - OctoPrint Room Temperature Plugin by Frederic Moutin.</li> <li><a href="https://github.com/guysoft/OctoPi">https://github.com/guysoft/OctoPi</a> - OctoPi Build by Guy Sheffer and the community.</li> <li><a href="https://shop.pimoroni.com/products/raspberry-pi-zero-camera-module">https://shop.pimoroni.com/products/raspberry-pi-zero-camera-module</a> - Camera Module for the Raspberry Pi Zero W.</li> </ul>
