Machine Information

  • Owner: Backyard Brains
  • Who Can Use: Roger S., Josh W., and Zach S. currently have experience running this LASER. Greg G., and Tim M. purchased it. Accordingly, they can do whatever they want with it ; )

Status: Temporarily Operational

  • The machine is up and running, but we lack:
    • Permanent filtering/ventilation
    • Documentation
    • Price info

Josh Williams is currently the primary contact for the installation process.

General usage information

Turning everything on

  1. Turn on the Power strip next to the computer
    1. This should turn the chiller on which makes a beeping noise for 5-10 seconds.
    2. If you don't hear a beeping noise, something is wrong. Please stop here.
  2. Turn on the computer
  3. Turn on the LASER Cutter using the laser key.
    1. Key is located in the laser cutter toolbox above the laser computer.
      1. The bed of the laser should light up, if not there is an on off switch on the side of the laser below the control panel.
  4. Turn on the Filter (temporarily located in the boiler room behind the laser cutter)
  5. Turn on the Blower (temporarily located in the boiler room behind the laser cutter)

File prep & loading your material

  1. On the computer, launch "LASERCut 5.3" from the desktop
  2. Place the material you are cutting towards the center of the laser bed
    1. If the bed is too high, use the "Z-" within the lasercut software to lower the bed.
  3. Use the x and y panel within the Lasercut software to position the laser head at the top left corner of your object
  4. Use the "Z Datum" button on the computer to set the laser at the right height.
    1. The laser must be positioned on top of your material for this to work accurately
  5. Adjust your speed & power settings in the top right hand corner in accordance to your needs.
    1. This has not been covered yet.
  6. Set the laser origin to "top left" by:
    1. Select everything (Ctrl-A)
    2. Tools Menu -> Set laser origin
    3. Check "Relative to Selection" and choose "Left-top"
  7. Select the "Pick" mouse cursor tool
    1. Make sure your design is still selected
    2. Hit the Space Bar
    3. Select "Left-top"
  8. Unite lines
    1. Select all of your design
    2. Click the "Tools" menu
    3. Choose "Unite lines"
      1. This should make your life easier. When you import an item into lasercut it generally breaks up all of your lines into individual lines to cut, stopping and starting the job instead of running a continuous line. However, it might do funny things. It's best to zoom in to your design to get a better idea of what's happening. The zoomed out view does not show as much detail.

Test

  1. When you have everything setup, click "Download"
    1. Select "Download Current" to load your design on to the laser cutter
    2. Select "Run Box" to do a perimeter test.

Burn

  1. Double check to make sure the filter, blower, and chiller are on.
  2. Click "Start" to begin your burn.
  3. Do not leave the laser cutter while your burn is going

Interesting Issues

  1. When running an outline of a Moai head, the laser stopped and started at various points for a very brief moment.
    1. We simplified the outline in inkscape and made sure to unite lines in lasercut 5.3. This helped, but we still stop/start problems with the laser.
  2. It appears that if your image/vector file is greater than any dimension of the bed (140cm * 90cm), the software will crash upon opening.

Steps to get it running

  • Reconnect electronics (disconnected during leg removal)
  • Go over LASER cutter, compare with manual.
  • Install Tube
  • Connect power to LASER Cutter: Boots
  • Connect Air Compressor to LASER: Working
  • Connect power to Chiller, connect alarm cable to laser: Works
  • Test Jogging X/Y/Z
  • Super brief test firing: Works
  • Align Mirrors
  • Figure out placement of computer/monitor
  • Install lasercut software & test connection to laser
  • Remove Metal Cutting Board (below honeycomb)
  • Fix hood closing issue (catches on right side)
  • Install hood handles
  • Organize Air & Water Tubing
  • Mount Air Compressor to floor
  • Where is hole for ventilation?
  • Where to exhaust to?
  • How much to exhaust out of building (top)
  • Filter: We are testing the RSU 20CCHR Electrocorp

Notes specific to the install at AHA

  • Water Chiller installed underneath laser. Pull laser forward ~4' in order to access. Be careful to avoid crushing or pulling out tubes for air & water
  • Air Compressor installed underneath laser. Pull laser forward ~4' in order to access. Be careful to avoid crushing or pulling out tubes for air & water
  • Currently two power strips are utilized, each connected to a separate circuit
    • The laser itself connects to the red spray painted outlet. This circuit is accessible from two other places within AHA. This should be avoided!
    • The Computer and Water chiller connect to the outlet adjacent to the red spray painted outlet. The blower will also likely be connected to this outlet
