How the Laser Works
Cutting vs Engraving
●Cutting is simplest, just a continuous beam of laser cutting:
Materials You Can Cut
●Acrylic●Wood/Plywood●Paper●Fabric●Leather●Nylon●Felt
Cutting Plastics vs Biologicals
●Cut multiple passes on plastics to avoid melting
●Cut one pass on biologicals (mostly woods) to not re-burn already burnt material
Cutting vs Engraving
●Engraving is a scan function. It cuts lightly, very fast, in many tiny passes:
●Doesn't need to penetrate entirely.
Materials You Can Engrave●Glass●Granite●Ferric Metals●Non-ferric with a coating (CerMark)
CerMark● $65/bottle spray* that lets
you engrave non-ferric metals

Things with lots of these make bad gases
Things NEVER to Use in the Laser
Things NEVER to Use in the Laser●Lexan●Vinyl●PVC●Teflon●Hint: anything that turns yellow when cut:
●If unknown/not on chart, ask before using

Datum: Resets the Laser Head Positions
Laser: Fires Test laser beam(*pew*)
Stop: Halts and Cancels Cut
Lighting: Turns on/off internal lighting
E-Stop:FUUUUUUUUUUUU-
Key: Turns on/off laser cutter
Table Up/Down: Moves work table up/down to bring items in and out of focus (like moving closer/further from a camera)
Jog Arrows: Moves focal head around table
Esc: Press this all the time to get the laser to do what you're telling it to
Start/Pause: Starts/Pauses the loaded Cut
Test:Has head trace the outline of the cut loaded
The Control Panel
Focusing the Beam
● Start with table high● Fire test laser dot● Move table down● Fire another test dot
(should be smaller)● Continue to fire till dot
gets bigger● Move the table back up a
bit again, now you're in the middle
Lens Cleaning
Lens Cleaning
Cleaning agents:●Alcohol for wood/paper/particulate●Acetone for plastics based materials
Process●Mix Alcohol/Acetone 1:1 and soak the lens●Open tube, get out lens●Wipe lens lightly with Q-tips (don't rub!)●Dry lens by wiping with kimwipes (don't rub!)●Re-assemble tube, align markings
