Usually, this +is <cite>~/.config/kicad/scripting/plugins/</cite> for KiCAD stable installations or +<cite>~/.config/kicad/[major version].99/scripting/plugins/</cite> for nightly builds. On Windows, these paths can be found in your +user account's <cite>AppData/Roaming</cite> directory.</p> +<p>To install the footprint libraries, the easiest way is to download the library zip from the project's repo +<a class="reference external" href="https://git.jaseg.de/kimesh.git/plain/mesh_footprints.tar.xz?h=main">[link]</a>, unpack it to your project folder, and +add the unpacked libraries as project-specific libraries through KiCad's library management thingy.</p> +</div> +<div class="section" id="usage"> +<h2>Usage</h2> +<p>To work, KiMesh requires four things:</p> +<ol class="arabic simple"> +<li>An area free of other features such as footprints or traces where to generate the mesh.</li> +<li>One or more "graphic polygons" on a drawing layer that specify the area of the mesh.</li> +<li>A closed board outline on the <cite>Edge.Cuts</cite> layer.</li> +<li>One of the magic footprints from the KiMesh anchor library that defines the mesh's number of wires and their +dimensions, and tells KiMesh where to start the mesh and in which direction to start it.</li> +</ol> +<p>You can choose any layer for the outline polygons, such as the pre-defined <cite>User.Eco1</cite> or <cite>User.X</cite> layers, or you can +define your own. You just have to select that layer later in KiMesh's generator dialog. Note that KiMesh only processes +graphic polygons on that layer, and ignores other shapes such as lines, rectangles or circles. You can still use other +shapes, but you have to manually convert them to polygons before running KiMesh. To convert other shapes to +a polygon, select them, open the context menu with a right click, then choose the "Create from Selection 🞂 Create +Polygon from Selection" entry. For rectangles or circles, use the "Use Centerlines" option. For lines or arcs, use the +"Create bounding hull" option.</p> +<p>Place the magic anchor footprint on the outline of the mesh's shape polygons so that you have space to route out the +traces. The anchor footprint has an arrow on the <cite>F.Fab</cite> layer that indicates in which direction the mesh will be +generated.</p> +<p>I recommend adding the mesh to the schematic with one of KiCad's built-in <cite>Connector_02xN_Top_Bottom</cite> footprints. For a +mesh with k wires, choose a symbol with two rows of 2k pins each. For instance, for two mesh wires, choose +<cite>Connector_02x04_Top_bottom</cite>. Then assign one of the magic footprints to that symbol. To avoid DRC warnings, join the +two halves of the mesh on the output side of the footprint. That's the right side in default orientation, where the +higher-numbered pins are.</p> +<img alt="A screenshot of the connector footprint mentioned in the previous paragraph, shown conencted up as described in KiCad's schematic editor." src="screenshot-mesh-schematic.png" style="width: 800px;" /> +</div> +<div class="section" id="theory-of-operation"> +<h2>Theory of operation</h2> +<p>I have published a <a class="reference external" href="https://blog.jaseg.de/posts/kicad-mesh-plugin/">post</a> on my blog on the theory of operation behind KiMesh.</p> +</div> +</div> + </main><footer> + Copyright © 2023 Jan Sebastian Götte + / <a href="/about/">About</a> + / <a href="/imprint/">Imprint</a> +</footer> +<script> + if(navigator.getEnvironmentIntegrity!==undefined)document.querySelector('body').innerHTML=`<h1>Your browser + contains Google DRM</h1>"Web Environment Integrity" is a Google euphemism for a DRM that is designed to + prevent ad-blocking, and which Google has forced into their browsers against widespread public opposition. + In support of an open web, this website does not function with this DRM.
