There are many videos urging new diode users to choose thier engraving parameters by using the matrix test.. You can create your own or there is a preset template within Lightburn. This simple test sadly prevenets diode users from ever understanding what happens to the "burn line" when thery change speed and power.
This session is a VERY deep dive into all the factors that affect the "colour" of non-binary materials such as wood or leather that can be burnt to create a palette of browns. Demonstrating what each parameter does to "colour" and why, will quickly illustrate the deficiencies of the matrix test. Finding good engraving parameters involves so much more than just speed and %power.
Another misconception is that you can control the power of a diode laser with the %power parameter.. Wrong. A diode laser is either ON (full power) or OFF.. How the PWM control system tries to create the illusion of power control is explained in detail and how the matrix test colours are not what they seem.
