Unable to callibrate laser camera, callibration image is just a blank piece of wood

Hello, I have a problem related with the laser camera calibration. The machine I’m using is the Snapmaker 2.0 A250 with the 1.6W laser module. I’m using the Luban software to operate.

My machine has been gifted from a friend and was already been used by him mostly for 3d printing. The status of the machine is good as new and I’ve already used it myself for 3d printing and engraving with the laser.

I have the machine updated to the latest firmware version.

The problem with engraving is the camera feed, which the final image is out of shape and I need to calibrate it. However following the instructions from this video I should see from the Luban software an image with a square in the callibration menu but instead what I get is an image of a blank piece of wood. I’ll put the images for what I should get and what I get in this post.

The piece of wood that show on the image is not mine, so that image has been taken somewhere else. The piece of wood I want to engrave looks completely different.
I asked my friend if he recognizes the image but he doesn’t remember because he may have used the laser module once or twice since he got the machine.

I haven’t managed to figure out how to retake this image. What should I do?

This is my first post on this forum, I hope the image quality is good enough and that I’ve given all needed informations to find a solution for my problem.

Haven’t done this for a while.

If you have a enclosure or any foreign light, be sure to turn the light off.

You have to calibrate the camera from the touchscreen, this will prompt you to lay a piece of paper on the bed where the square gets cutted after.

After this process you should be able to do the square alignment in Luban.

Hope this helps!

Okay, thanks!
I’ll do that as soon I can and reply if the problem will be solved or not. :slight_smile:

Hello again, after I’ve finished my setup I tried your advice @xchrisd and successfully configured the camera.

The photo got retaken with the square for callibration.
