Core One Wiper Path Generator

For use with Core One Nozzle Wiper V2 with Purge Bin and similar front-mounted nozzle wiper arms.

A browser-based tool for generating a nozzle wiping path for the Prusa Core One that uses a Bambu Lab A1 (or equal) silicone wiper pad. The app guides you through calibrating the pad position, configuring plunge depth/feed rates, sketching the wiping path on an overlay of the pad, and exporting ready-to-run G-code.

This is an unofficial, community project. Always verify G-code before running it on your printer.

Built with SolidJS, Vite, and Tailwind CSS.

Prerequisites

• Node.js 20+ and npm
• Modern browser for running the UI locally

Install dependencies

npm install

Run the app in development

npm run dev

Then open the URL shown in the terminal (defaults to http://localhost:5173). The dev server reloads on file saves.

Build for production

npm run build

Outputs the optimized static assets to dist/. You can sanity-check the build locally with:

npm run preview

Optimizing images

Images are stored as WebP in the repo for optimal file size. When adding or updating images:

1. Convert PNGs/JPGs to WebP using ImageMagick:

   magick input.png output.webp

2. Optimize SVGs with SVGO:

   npx svgo input.svg -o input.svg

3. Update imports: image files are imported via Vite with the ?url suffix (e.g. import img from './image.webp?url').

4. Add alt, width, and height to all <img> elements to prevent layout shift and improve accessibility.

Material Symbols icon font

The icon font is a self-hosted subset containing only the icons used in the app (see src/assets/fonts/). To update the subset when adding new icons:

1. Build the full icon list from symbol= props and msIcon= props across the codebase.
2. Fetch a new subset from Google Fonts:

   https://fonts.googleapis.com/css2?family=Material+Symbols+Rounded:opsz,wght,FILL,GRAD@24,400,0,0&icon_names=check,close,...
   

   Use a browser User-Agent header to get woff2 format.
3. Download the woff2 file and replace src/assets/fonts/material-symbols-rounded-subset.woff2.

Code quality

• npm run lint: lint the codebase with Biome
• npm run format: format files in-place
