  • Permanent filtering/ventilation
  • Documentation
  • Price info

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

Usage Information

1. Turn on 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 (you will need a key, currently located in the LASER Cutter Toolbox above the LASER Cutter computer
   1. The bed of the laser should light up, if not there is a on off switch on the side of the laser to 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)
6. On the computer, launch "LASERCut 5.3" from the desktop.
7. Open or create your file that you wish to lasercut. This document does not currently cover how to do this
8. Place the item you are cutting on the laser bed
   1. If the bed is too high, use the "Z" within the lasercut software to lower the bed.
9. Use the x and y panel with the lasercut software to position the laser head above your object
10. Use the "Z Dataum" button on the computer to set the laser at the right height
11. When you have everything setup, click "Download" and choose "Download Current" to load it on to the laser cutter
    1. double check to make sure filter/blower/chiller are on.
    2. Click "Start" to fire
12. Remember to download your file before doing the "Run Box" perimeter test
13. Tape your object down if it's light (ie: paper)

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?

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
