Laser Power & Speed Calculator

About this app

Suggested power and speed settings to give you a starting point - and a general idea of what settings to use for your circumstances.

Your settings may require some tweaking. Some factors to consider are ambient temperature, water temperature, tube age, focus accuracy etc. If in doubt, use the lowest power possible.

To use this calculator, click your Rated Laser Output Power, then select Cut or Engrave, and then the material you intend to use.

The values we use to calculate Power and Speed settings were measured by Perfect Laser South Africa on our own machines. Readings were taken with material from Cape Town. Your material may differ.

Ratings and reviews

This App provides great starting point settings, lasers can be slightly different in the initial PSU settings from the factory, this utility will get you close. Update & FYI 06/30/2026; There were a couple of "bugs" in the recent 2.0 update, my device was affected so I sent an email to the developer. They were on it immediately & fixed it. Support like that is rare these days, if I could give them more than ⭐⭐⭐⭐⭐ I would. Beyond that the expanded list of materials is very helpful.

great for start of settings - i have used these to begin refining my own settings fir my machines. would be nice to be able to add other materials or modify to be able to build a library of settings custom to the user.

This app frequently helps me find a useful setting for my 60W OMTech laser. Obviously, each machine varies with focus and cleaning.
