Laser Calibration Card?

Hello fellow Snabmaker users!
I’m using my laser module for the first time, but I’m a bit puzzled. The manual says to use the “Laser Calibration Card”, but I can’t find a seperate card for this. Is there a PDF version of this card that I could print out, or do I simply use the picture printed in the manual?

Thanks!

I lost my card, so I can’t verify. I’m pretty sure it was on the back side of the piece of paper used for 3D printing calibration.

I haven’t seen a PDF of the card anywhere. I’d scan mine if I could find it. I’ve been using ordinary printer paper to rough in the 3D printer calibration, followed by a 0.05mm thick square to really dial in the calibration.
