Calibrating Axes In LightBurn

Preface: This article covers how to easily calibrate an Axis in Lightburn using the built in wizard

Make sure you back up the Laser Machine Settings before you edit them:  Backing Up Machine and LightBurn Settings

Tools you will need:

Accurate measuring device (metal ruler, caliper)

Scrap Material

Laser and Computer

Adjusting for Kerf:

Understanding Kerf and Kerf Offset

When scoring a square, the score line has a small but finite width. This width is the kerf and needs to be accounted for. When you measure, you want the "center to center" measurement from one kerf line to the other. It is easier to measure to the left of both Kerf Lines or to the right of both Kerf lines.

The Procedure:

When drawing and measuring your test shape, you need to make your shape as large as possible and be able to measure it accurately. This will help limit compound error. Compound error is when you are off for example by .01" on a 1" square, that equates to .5" on a 50" square which is not acceptable. Being off by .01" for a 25" square will yield better results.

1. Draw a large enough square in lightburn and set it up to score with a speed of around 150mms and power around 15pct.

2. Mark the square onto a piece of scrap material

3. Measure the square and input the dimensions into the lightburn wizard (See video down below)

4. Repeat until the drawn dimension in lightburn matches the scored material.
