The corner calibration is generally required if one of the pink markers has been removed, or if there is a bigger deviation between the screen picture and the laser result. It relies on the four pink markers to successfully calibrate the camera.

1. When do I need to calibrate the camera?

A new calibration of the camera is only necessary:

  • If one of the pink markers has been changed. (For example, if the mark was peeled off and glued in place again.) 
  • If you notice a larger deviation between the screen position on the adjusted (black-and-white image) and the laser result.
  • After a laser head cleaning or replacement.

When switched on and with an open lid, Mr Beam should display a black and white image of the working area. This image is suitable for camera based positioning of your designs, but a slight offset of up to +/- 5mm should be tolerated. If you see blinking pink circle markers in the corners of the working area, camera positioning might not be very accurate. In this case we recommend looking at solutions suggested in the following article.

2. How do I calibrate the camera?

1. Start corner calibration

If a calibration needs to be done, please open the menu in your Mr Beam software and click on Settings > Camera, then scroll to the bottom of the page and click on "Start" at Corner Calibration. It is best to use a piece of cardboard or felt for the engraving.

2. Follow steps

Follow all the steps listed in the software:

Tip: If you have the Mr Beam Height Extension installed, you will need to follow an extra step when engraving the arrows. Click here for more detailed information.

Tip: Use only thin material such as paper or flat cardboard for the corner calibration. It is important for this process to laser at height 0, i.e. directly on the bottom of the grid. To prevent the material from slipping, you can also laser directly onto masking tape or an adhesive paper pad.

3. What changes if I have the Mr Beam Height Extension installed?

Basically, the procedure remains the same even with the Height Extension installed. However, the engraved arrows must be engraved at the same height as on the original base. 

Therefore, insert a solid sheet of paper (e.g. a business card) in all four corners between the case and the Height Extension (see picture below). Then you can proceed as usual and engrave the arrows on the pieces of paper.
