Machine Information

  • Owner: Backyard Brains
  • Who Can Use: Roger S., Josh W., and Zach S, Alex C., Vanya P., Nick R. currently have experience running this LASER. Greg G., and Tim M. purchased it. Accordingly, they can do whatever they want with it ; )
  • How can I use it?
    • Talk to Josh or Zorica with Backyard Brains as we have yet to finalize an access path for this machine. In short: If you haven't been given permission by Zorica or Greg of Backyard Brains, please don't use 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.

How to use this laser cutter

  • You must be checked out on this LASER before using it. Get checked out by taking the class!
    • We currently charge $0.50 p/minute of burn time for the LASER.

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.

Occasional divets noticed when cutting through acrylic

Material: 3mm Clear Acrylic

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
