General Things for Using Laser Cutter

Speed: It decides the movement speed of the laser head. To engrave and cut thin material, the speed is usually set to the maximum.

Frequency (Hz, PPI): It specifies the number of laser pulses per second. For instance, wood cuts are best at 500 to 1000 Hz. For acrylic, 5000 to 20000 Hz is the minimum requirement.

Focus: There comes a focus lens inside the laser head. It should be on the surface of the material or slightly below for most of the applications. Make sure that materials are at a certain distance from the lens. The exact distance depends on the type of focus lens.

There are so many types of laser machines that come with a motorized bed. You can move up and down to set the focus distance. And the position of the material surface should be also manually adjusted.
