But when looking at the backside you do see a difference with how much it burned. From there I think the best values for cardboard are high power and high speed 100s/100p or medium speed and low power 40s/25p.
We also had one small little incident when we where cutting out the letters. The laser was too too each letter so the cardboard got hot and burned a little. We also noticed that our laser couldn't output a laser at 10 power. So that's why we stopped measuring it in the rest of the tests.
These tests up here could be a fluke because all the minimum powers where left unchanged and random.
#### Karf test
So we did all the test with exactly 10 centimeters. So there are 11 cuts.
