The power adjust knob on this k40 laser cutter didn’t have a dial of any sort so it was hard to set power values for different materials like cardboard and acrylic.
Here is a picture of the dial:
To cut it out you could laser cut and etch it or print it out on paper and cut it out with a blade. The svg file linked below has the correct dimensions for the dial so it should print the correct size.

You should have made a dial that goes up to 11!
May I just ask you the vendor name, and the way that you choose to bought this machine (ebay, …) ?
Thanks in advance,
Hey Thierry, I bought it from Amazon.de and the seller name is FurMune. Here is a link to it: https://www.amazon.de/FurMune-Graviermaschine-Maschine-Engraving-Unterst%C3%BCtzung/dp/B015MFP4HQ/ref=sr_1_1?ie=UTF8&qid=1465921386&sr=8-1&keywords=40w+laser+cutter
Many thanks for your quick answer !

What are your materials and known settings?
Excellent, just what I was looking for, I’ve been wondering how to make a dial and mark the gauge accurately.
Awesome little hack. Cheers might add this when i can find 2 minutes to do so. There are a few settings here https://k40lasercutter.com/recommended-k40-laser-cutter-settings/ which I’ve noted down, and I might add an arrow over the top to turn dial for certain product materials as well and create a graph for easy reference
