KerfLab Terms of Service

Last updated: February 2026

The Short Version

Before the legal language, here's what you need to know:

Your Responsibility

  1. Always verify G-code before running it. KerfLab generates toolpaths based on your inputs, but you must check that they're safe for your specific machine, material, and setup.
  2. You know your machine better than we do. Feed rates, spindle speeds, and cutting depths that work on one CNC may be dangerous on another. Adjust settings accordingly.
  3. Test cuts are your friend. Run new programs in air first, or on scrap material, before committing to expensive stock.
  4. We can't predict everything. Material inconsistencies, machine calibration issues, firmware bugs, or worn tooling can all cause problems that no software can anticipate.

What We Promise

  • We'll do our best to generate correct, safe G-code based on your inputs
  • We'll fix bugs when we find them
  • We won't sell your data or project files to third parties
  • Your designs remain yours

What We Don't Promise

  • That G-code will work perfectly on every machine
  • That you won't damage material, tooling, or your machine
  • That the service will be available 100% of the time
  • That our nesting algorithms will always find the optimal solution

If you're not comfortable taking responsibility for verifying G-code, this software isn't for you.
