What this site is
feedsandspeeds.us is a pair of free reference tools run by VARØ Industries: a CNC feeds and speeds calculator for routers and mills, and a Glowforge material settings reference at /glowforge. Neither tool has accounts, and neither asks you to type in personal information.
Calculations happen in your browser
The material, bit and router choices you make are processed by JavaScript on your own device. The data tables (feeds.csv and routers.csv for the CNC tool, settings.csv for Glowforge) are static files on this site that your browser downloads, so nothing you select is sent to us. Print and CSV export are generated locally.
Local storage
If you accept the storage notice on the CNC calculator, it saves your theme, unit system and dropdown selections in your browser's localStorage so they are there next visit (keys cookieConsent and feedsSpeedsPrefs). If you decline, nothing is saved. The Glowforge page stores your light or dark theme choice (gf_theme) the same way. You can clear these at any time through your browser's site data settings.
Third-party resources and logs
Pages load the Tailwind CSS script from cdn.tailwindcss.com, the PapaParse CSV library from cdnjs.cloudflare.com, and fonts from Google Fonts. Your browser contacts those services when a page loads, so they receive your IP address and user agent under their own policies. Like most web servers, ours records standard access logs (IP address, time, URL, user agent) for security and troubleshooting.
Affiliate links
The Glowforge page includes Amazon Associates links to some products. If you buy through one, Amazon may pay us a commission at no extra cost to you, and Amazon may set its own cookies once you reach its site.
Google Analytics and advertising
This site uses Google Analytics to measure how many people visit and which pages they use, and it may display ads served by Google AdSense. Both are loaded from Google servers and can set or read cookies in your browser.
Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this and other websites. Google's advertising cookies enable it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet. You can opt out of personalised advertising by visiting Google Ads Settings.
