Left Laser Protocol Upgraded Air Assist

This guide will outline all the steps to use the upgraded air-assist on the left laser.

1. Dry out the dessicant (this prevents water from the compressor from getting on the laser lens, which can cause damage)

• This should be done each day at open. Check to see if the date is current (today’s date). If it shows today’s date, skip to step 2.
• If the dessicant has not been changed today, carefully unscrew the desiccant container.
• Set up the oven outside on the balcony bench, and empty the desiccant into the aluminum foil tray
• Bake for 30 minutes or until dessicant turns blue.

2. Turn on the air

• Go into the woodshop and make sure the compressor is plugged in
• Check the red lever on the compressor and turn it on (flip to the DOWN position).
• On the right side of the laser, find the valve at the back of the Air Assist Assembly (where the hose comes in).
• Make sure the valve is ON (parallel with the air hose)
• Make sure the airflow meter valve is OPEN (twist knob to the left)

Special Focus Instructions

The left laser has been fitted with a nozzle that is 10mm longer, which blows air much closer to the piece.

To focus with this nozzle:

1. Follow normal focus procedures (see infographic on the wall next to the laser)
2. Move the laser bed UP 10 mm.

• Look at the Z position on the small screen on the laser. It will read something like 2986.
• Subtract 10 from this number (that’s 2976).
• Move the laser bed UP (using the left arrow in the Z menu) until the Z position reads ten less than your original position.

3. Review standard pre-cut checklist
4. Fire ze laser!
