Customizable front panel button for Anycubic Kossel

prusaprinters

<p>A customizable button for the front panel LCD (a RepRapDiscount 2004) on the Anycubic Kossel line of printers (including the Anycubic Kossel Plus / Anycubic Kossel Linear Plus). Based on @HaTomX's Kill Button for Anycubic Kossel, but redone in OpenSCAD and with a few tweaks.</p><p>Since the STL previews don't show the text without using Thingiview and looking at the bottom of the print, I have provided the following options:</p><ul><li>PANIC!</li><li>STOP!</li><li><a href="https://fontawesome.com/icons/exclamation-triangle">Exclamation triangle</a></li><li>$#!%</li></ul><p>*<i>A back arrow</i></p><ul><li><a href="https://fontawesome.com/icons/chevron-circle-left?style=solid">back chevron</a></li></ul><p>I use <a href="https://www.klipper3d.org/Features.html">Klipper</a> for my Kossel Plus, so it is easy to reconfigure the purpose of the button on the LCD panel. I trust the power switch more for an emergency stop than a pin which needs to be sampled by software, and it is also on the front of the printer. Therefore I decided to repurpose this button as a quick "back" button for the LCD menus.</p><p>This can be configured in Klipper with the following in printer.cfg (this requires <a href="https://github.com/KevinOConnor/klipper/blob/master/config/generic-ramps.cfg#L86">board_pins aliases to be setup</a>):</p><pre><code class="language-plaintext">[display] #kill_pin: ^!EXP2_8 back_pin: ^!EXP2_8</code></pre><p>This could also be repurposed in Marlin, but that requires recompilation of the firmware.</p><p>Several pre-generated STLs are provided, but the customizer (or OpenSCAD itself) can be used to generate custom text / icons. If using OpenSCAD offline, you will need to install the Font Awesome Free fonts: <a href="https://fontawesome.com/download">https://fontawesome.com/download</a> and potentially Google Fonts if you want to use those: <a href="https://fonts.google.com/">https://fonts.google.com/</a> (such as "Share Tech Mono" or "Orbitron").</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Anycubic</p><p><strong>Printer:&nbsp;</strong></p><p>Kossel</p><p><strong>Rafts:</strong></p><p>No</p><p><strong>Supports:&nbsp;</strong></p><p>No</p><p><strong>Resolution:</strong></p><p>0.1</p><p><strong>Infill:&nbsp;</strong></p><p>15%</p><p><strong>Filament:</strong> Inland PLA Egyptian Blue</p><p><br>&nbsp;</p><p><strong>Notes:</strong></p><p>&nbsp;</p><p>May need to set "Minimum Infill Area" to something like 20mm^2 in order to keep the pin solid.</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>Category: 3D Printer Parts</p>
