Committees are voluntary groups, formed by members in order to achieve certain goals.
To join this committee, contact the committee chairperson. See Rules and Policies#Committees for more information.

Purpose

The Laser Committee covers:

  • Training members in the safe, effective use of the Lasers
  • Care and maintenance of the lasers (The Epilog Zing and Thunder Novas)
  • Consumables of the lasers (Lenses, Mirrors, Laser Tubes, Supplies, etc)
  • Maintenance of the laser computers in cooperation with Infrastructure
  • The list of acceptable materials for use with the laser cutter. Ask if questionable.
  • Promotion of interest in laser technology.
THE WIKI IS THE OFFICIAL RECORD OF THE COMMITTEE.
MEMBERS ARE SOLELY RESPONSIBLE FOR KNOWING THE CONTENTS OF THE WIKI.
THE WIKI CHANGES AS THE LASER COMMITTEE BECOMES MORE KNOWLEDGEABLE ABOUT THE OPERATION AND MAINTENANCE OF THE LASERS.

TO STAY UP TO DATE:  ADD THIS PAGE TO YOUR WIKI WATCHLIST TO RECEIVE CHANGE NOTICES.  

ADDITIONALLY, SUBSCRIBE TO THE LASER CATEGORY ON TALK. JOIN THE LASER DISCORD CHANNEL. READ THE WHITEBOARD. CHECK OVERHEAD MONITOR FOR PUBLIC SERVICE ANNOUNCEMENTS.  RE-TAKE LASER 101 THUNDER BASICS or LASER 102 ZING BASICS FOR A REFRESHER. JOIN TEAM LASER; WE MEET MONTHLY.  

HAPPY LASERING!

Laser Area Rules...or act like a Member, not a Customer.

MUST have completed training.

Laser 101 Thunder Basics course to operate the Thunder Nova lasers.

Laser 102 Zing Basics to operate the Epilog Zing.

MUST monitor laser for the duration of your job. Stay within arms reach at all times.

If you use a proxy to watch the laser, they also must be Laser 101 or Laser 102 trained, depending on laser, and be within arms reach.

Desperately need to use the restroom but no Laser-trained proxy? We understand. Hit the pause button. Put a sign on the laser lid with name, cell number, and time. Return promptly. Next time plan better because Rule #6 "Honor the queue". DO NOT abuse our understanding by using this loophole for getting a snack from the galley, visiting with friends, leaving the premises, etc.

You shall not run multiple lasers at once as you cannot monitor them both or stay within arms reach of both.

Why? Because Lasers cause fires. We have a 4-part fire suppression system: you, the CO2 line, the fire extinguisher, and the fire alarm. None of these work without you. A fire risks not only a $15,000 laser, but also the facility and everyone in it.

PAY FOR USAGE!

$1 per 5 minutes of laser runtime, rounded up. Example: 4 min = $1, 6 min = $2.

Credit cards (preferred) and cash accepted at Laser. Swipe credit cards at Square kiosk. Record cash payment in Square kiosk and take receipt. This is the only proof of payment. If you do not record cash payment in Square, it may look like you didn't pay. You are responsible for keeping this proof of payment. Put cash in envelope (see side pocket on cash box); write name, date, and "Laser" on envelope for bookkeeper; submit in tall black cash box under Square kiosk.

Multiple jobs during one visit? Add all the runtimes together, then round up.

MUST be made at the time of your visit.

Failure to pay is theft of service and will result in expulsion and prosecution. We have done so. Be aware that under Texas Penal Code Section 31.03(f) "an offense described for purposes of punishment by Subsections (e)(1)-(6) is increased to the next higher category of offense if it is shown on the trial of the offense that the owner of the property appropriated was at the time of the offense is a non-profit organization." A misdemeanor elsewhere may be a felony against Dallas Makerspace. It's not worth it. Pay.

Accidentally walk out without paying and can't turn around to come back? Don't panic. Notify us on Talk. We'll respect your prompt honesty and you'll set a good example. We'll work something out.

NO cutting of prohibited materials. Link to list below.

See the Go/No-Go List of Materials.

It is the member's responsibility to know the content of their materials. No exceptions. If it is not on the list, if you are uncertain, if you can't locate an MSDS, don't use the material. Post a question on the Talk forum using the Laser category and we will do our best to help.

BE excellent and clean up after yourself.

Tidy up tools and trash. Remove bits of material from laser beds. Do not leave scrap in Laser area. Be honest with yourself; is it really usable scrap? If yes, place on shelf in Workshop or under the Laser worktable. No room on shelves? Take usable scrap home...or throw it away...or throw away existing scrap to make room. Otherwise, throw bad scrap in the trash can or dumpster. Empty the trash can in the dumpster. Join us on the monthly Maintenance Day for a deep cleaning.

HONOR the queue.

Don't waste time at the laser. If you have a long job and there is a queue, let shorter jobs play through. Call or text the next person in the queue after your turn. Don't jump the queue.

NO HOGGING the computers.

They're for importing your prints, not creating your designs. Tweaking a design is expected, however.

In case of EMERGENCY, use the red E-STOP button.

Use the fire suppression equipment: the CO2 blue line or the fire extinguishers. There is a fire extinguisher on the floor next to each laser. Notify us of issues on Talk.

DO NOT perform maintenance on the lasers.

We have a maintenance team for that. Notify us of issues on Talk. Join the team and get the skills to do it yourself.

CONSEQUENCES

If you are observed violating committee rules, we may take the following actions:

  • we may not allow you to complete your job.
  • we may suspend your access to the Laser Area up to the maximum time permitted by the Dallas Makerspace Rules.
  • we may invalidate your Laser 101 and Laser 102 training. Why? Because you have forgotten your training.
  • we may petition the Board for stricter consequences.

Unless the situation warrants us petitioning the Board, you have a path forward. You may get re-certified by participating in a Monthly Committee Meeting/Maintenance Day. Our committee does not want members who have lost their authorization to re-take Laser 101 Thunder Basics or Laser 102 Zing Basics. Those limited slots are kept available to members-in-good-standing. We have a Committee Meeting/Maintenance Day once a month.

Tools

A CNC laser cutter is a computer controlled tool for engraving and cutting. It uses a high-powered laser to burn through material, leaving a very crisp cut.

Thunder Nova Lasers

Notes Regarding Head Crashes:

  • Don't put anything in the way of the head so that it crashes.
  • The Thunder Laser Nova 35 & 63 have servos (steppers with optical encoders). If it senses a lot of skipped steps it just gives up and assumes something has gone terribly wrong. This can crash the head. Resetting the machine clears things and it should go back to normal operation.
  • The "reset" button also helps when the machine loses track of its place. It forces a re-Home and then rights itself. This can happen with the rotary attachment too.

Epilog Zing Laser

Thunder Laser Rotary Tool Attachment

The Thunder Laser has a rotary tool attachment to work on round items, such as tumblers, mugs, glasses, bottles, etc. You may use the rotary tool if you have completed the laser basics class and are comfortable on the Thunder Laser. The rotary tool attachment is normally stored on the upper shelves of the scrap area. The following link has instructions on use of the rotary tool.

Link to Rotary Tool Instructions

If the wires become loose on the rotary attachment, the correct wiring is:
DIR- Red Wire
DIR+ Yellow Wire
PUL- Green Wire
PUL+ Black Wire
