The bed height must be adjusted to the thickness of your material so as to ensure the focus point of the beam is in the optimal position for your task. The focus point of the beam corresponds with the top edge of the vertical ruler that is attached to the back of the cutting area.

The focus point of the beam corresponds with the top edge of the vertical ruler that is attached to the back of the cutting area. It's worth noting that this is at the same height as the bottom edge of the horizontal ruler that runs along the length of the bed so may be easier to judge the correct height using that albeit a bit less intuitive to remember. So: | ||
* For cutting materials <=8mm, the bed height should be set to the focus point, making the bottom of your material the focus point of the laser (i.e. the top of the cutting bed should line up with the top of the vertical ruler). | * For cutting materials <=8mm, the bed height should be set to the focus point, making the bottom of your material the focus point of the laser (i.e. the top of the cutting bed should line up with the top of the vertical ruler). | ||
* For cutting materials >8mm, the bed height needs to be adjusted such that the focus point is in the mid point of the material. | * For cutting materials >8mm, the bed height needs to be adjusted such that the focus point is in the mid point of the material. | ||
