Preface: This article covers how to enter your scanning offsets properly and some steps to troubleshoot what went wrong and where to find your offsets if you lose the gold card.

If you have a new machine that was built and shipped around Q2 2023 or later, we recommend using the Easy Button to import your offsets and many other things.

How to Enter your Offsets:

      Offsets are what control the quality of your Engraving (Fill and Image Layers) when using Bi-Directional mode. If you do not enter the offsets right, you will have issues that can be seen here.

1. Open Lightburn and check your Units (mm vs in, seconds vs minutes)

Open Lightburn and click the Gear icon (Edit>settings)	Make sure you are in mm/sec mode (Can change back when done)

2. Open Up the Device Settings Window

Click the Gear\Screwdriver icon of Edit>Device Settings in Lightburn	Device Settings window pops up

3. Enable Offsets

      Go ahead and do this so that we do not forget. It does not good to have offsets entered but not enabled

      

Not Enabled (Red, Slider to the Left)	Enabled (Green, Slider to the right)

4. Enter Offsets using the Add Button

      Values will be entered into the Speed and Line Shift boxes only, nothing should be in the Initial Offset box except 0's

Click the Add button	Enter the values for each line. Repeat for all lines on the Gold Card

5. Check that everything looks right

       Lets compare the gold card to what is entered and check the units before we click and try to run a project

Check that your Gold Card Matches the Values you entered:	Check these 5 other things, then click OK twice to close the windows and save your offsets
	If any of the 5 things are not correct, then go back and fix and re-enter the offset values if needed.

What if you have lost your gold card?

Find them on your USB Stick:

The file referenced below may not be on your USB stick, the process to add the screenshot to the USB started around 2021.

1. Look for an Image File (png,bmp) on the USB	2. Use values in Red Box to enter into Lightburn
(Search around the USB as the file location can vary)

Find them on your Computer:

If you have previously exported a copy of your offsets or device profile, the offsets can be recovered from that.

Find them with your computers search function to find "*lbso" or ".lbdev" files:

Windows Example (will vary by OS revision)	Mac Example (will vary by OS revision)

Where to Import:

If you found a *.lbso File you will import the file in the Device Settings:

            

1. Click on the Gear\Screwdriver Icon or Edit>Device Settings	2. Import the file you found. Be sure to enable your offsets too

 

If you found a *.lbdev File you will import it as a new device (new Laser):

1. Click on the Devices button	2. Import the Device File you Found. Use the new device or copy offsets from it to your existing device
