# Calibration set

Calibration set: cut it once for every new material, before anything that has to fit. The kerf gauge measures the beam, the slot gauge how wide a slot your sheet needs, and the joint pairs which kerf setting makes finger joints that hold.

This design has 8 parts on 1 sheet. Customize it in the [playground](https://kerfscript.mylasertools.com/playground/?model=calibration-set).
