  1. 1. Laser Cutter Training
  2. 2. The Laser Cutter
  3. 3. The Laser Cutter ●Jinan King Rabbit Technology Development Co., Ltd. RL-150-1290 ●1290 = 1200x900mm = 47.2 x 35.4 inches cutting bed ●150w CO2 Laser ●Meant for high-power cutting, does engraves as well ●~4-5x as powerful as most hobbyist laser cutters
  4. 4. How the Laser Works Mirrors Laser Head Laser Tube
  5. 5. Material Vapor Infrared Laser Beam (invisible!) Compressed Air LineLaser Head Mirror How the Laser Works
  6. 6. Cutting vs Engraving ●Cutting is simplest, just a continuous beam of laser cutting:
  7. 7. Materials You Can Cut ●Acrylic ●Wood/Plywood ●Paper ●Fabric ●Leather ●Nylon ●Felt
  8. 8. 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
  9. 9. Cutting vs Engraving ●Engraving is a scan function. It cuts lightly, very fast, in many tiny passes: ●Doesn't need to penetrate entirely.
  10. 10. Materials You Can Engrave ●Glass ●Granite ●Ferric Metals ●Non-ferric with a coating (CerMark)
  11. 11. CerMark ● $65/bottle spray* that lets you engrave non-ferric metals *http://www.laserbits.com/index.php?main_page=index&cPath=356_487
  12. 12. Things with lots of these make bad gases Things NEVER to Use in the Laser
  13. 13. 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

  20. 20. 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: FUUUUUU UUUUUU- 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
  21. 21. 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
  22. 22. Lens Cleaning
  23. 23. 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
  24. 24. Operation Laser Cutter ●Main Body oOpen Compressor Valve oTurn on Ventillation oTurn on Laser Cutter oCheck Refrigerator oCheck Ventilation unit ●Computer oStart LaserCut 5.3
  25. 25. Design Software ●LaserCut 5.3 (simple, today's training) ●CorelDraw (has laser drivers) ●AutoCad (has laser drivers) ●Inkscape (free) ●Solidworks (on classroom computers) ●Adobe Illustrator Export to PLT or DXF
  26. 26. Select tool: Use to select, move, change properties Time: Show predicted cut time Simulate: check to make sure it will do what you plan Resize: Resize the selected object Layers: Hide/show layers Drawing tools: draw stuff! LaserCut 5.3 File: Import/export files, save job settings “The MSPaint of Laser Cutting”
  27. 27. Layers: Change order, operation (cut/engrave), cut speed, cut power, and repetitions Download: Download job to laser cutter Layer Colors: Change selected object to one of these layer colors LaserCut 5.3 “The MSPaint of Laser Cutting”
