Hobbyist Laser Calc is a free, no-login tool that helps hobbyist laser cutter users dial in their settings without the trial-and-error guesswork that wastes material and time.
Getting the right power, speed, and pass count for a laser job isn't obvious — it depends on your machine's wattage, the material you're cutting, and how thick it is. Most beginners spend hours searching forums, watching videos, and ruining test pieces trying to figure this out. This tool exists to short-circuit that process.
Enter your laser wattage, pick your material, set your thickness — and get a starting point for power %, speed, passes, kerf offset, and air assist in seconds. No account required. No ads cluttering the results. Just the numbers you need.
The calculator covers the most common hobbyist machines including diode lasers (xTool, Sculpfun, Atomstack, Ortur) and CO2 lasers (OMTech, Thunder, generic K40-style machines), and materials from softwood and plywood to acrylic, leather, and cardstock.
Settings are based on real-world tested data gathered from the hobbyist laser community — not theoretical specs pulled from datasheets. They're meant as a starting point, not gospel. Every machine is a little different, and dialing in from a good starting point is much faster than starting from scratch.
No account, no paywall, no upsell. Just open it and use it.
Runs entirely in your browser. Works on desktop, tablet, and phone.
Covers both major hobbyist laser types with separate setting profiles.
Wood, acrylic, leather, cardstock, and more — with thickness input.
If you find the tool useful, the best thing you can do is share it with someone else who's just getting started with their laser. That's how this stays free.
