These are a the instructions I use whenever cutting something at the Sacramento Hacker Lab.

Engauge (twist) the laser switch.
When cutting look for: Excessive smoke, flaring, mechanical errors, anything suspicious.

Wait for the smoke to clear.
Remove any foreign debris.
Disengage (push) the control, water pump, and air pump switches.

Adjusting the Z-Axis

Adjust the Z-axis by pressing the Z/U button then selecting the “z-axis move” from the menu, followed by pressing the left or right buttons to raise and lower the cutting tip. The proper height is established by lowering the cutting tip down until there is no airflow from the cutting tip.

Morntech Plugin

Adjust the layers cut order, with the outline shape being the last and any etchings the first.
Cut: 5 mm/sec@55%
Scan: 150-200mm/sec@11%+

Resetting the Laser

From time to time the laser may become disconnected from the host computer. Typically this will be expressed in the form of new files not being able to be loaded to the laser cutter. In the event that this does occur, simply unplug the USB cable from the laser cutter, wait 5 seconds, and plug the USB cable into the laser cutter. The Morntech plugin will need to be restarted, but it should save any changes that were made in the previous session.
