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.
Welcome to the World of DMS Lasering!
Congratulations on finding our wiki, the official record of the committee and chock full of useful information for members.
Makers are always learning, so the wiki changes as the Laser Committee becomes more knowledgeable about operation and maintenance.
Frequent changes makes it difficult for you, our members, to stay up to date.
Fortunately, wiki technology makes it easy.
Simply add this page to your wiki watchlist to receive change notices by email.  

Help govern the area by joining the Laser Committee.  There's always room for more people.  We meet monthly on the First Sunday.  Meeting runs from 11-noon, then we adjourn to clean the lasers and share a potluck (because this team marches on its stomach) until 2pm.   

Happy Lasering!

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

Must have completed training and meet Age Restriction.

  • Laser 101 Thunder Basics course to operate the Thunder Nova lasers.
  • Laser 102 Zing Basics course to operate the Epilog Zing.
  • Age Restriction: You must be at least 16 years of age to take the training.

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. Add a "Be right back" note to the laser sign-in board. Return promptly. Your session time limit does not get extended. 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 run-time, rounded up. Example: 4 min = $1, 6 min = $2.

Run-time: laser operating time as measured by the counter in the laser’s control panel.

  • 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. If you cannot find an envelope, re-stock them from the supply kept in the Common Room on top of the white shelving.
  • Multiple jobs during one visit? Add all the run-times 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.

Obey the queue and session limit.

Definitions

  • Workstation: area including laser and PC.
  • Session: when member occupies a workstation, whether laser is operating or not and whether user is logged into computer or not.
  • Run-time: laser operating time as measured by the counter in the laser’s control panel. A subset of session time.
  • Work piece: single lasered item that can be lifted out of the laser without ruining it. Note: your job may consist of multiple work pieces.
  • Off-peak hours: 10p-10a CST
  • Peak hours: 10a-10p CST

Queue Procedure

1. Queue Sign-In: Write your name, phone number and arrival time on it. Indicate if you are waiting for Big Thunder or Zing. Write clearly or you may lose your turn.

2. Tell laser operators that you are waiting in the queue. They may not realize that a queue has formed.

3. Answer your phone or text message promptly, or else you may lose your turn.

4. Erase your name and information from the queue sign-in board when your turn begins.

Session Procedure

1. Laser Session Sign In: Write your name and session start time on sign at workstation.

2. Session Limit:

Operator vacates the workstation under these conditions:

  • After 3-hours
  • AND when a work piece can be removed from the laser bed without ruining it
  • AND if people are waiting in the queue for the laser.

If no one is waiting for the laser, operator may continue to use the workstation until a queue for the laser forms. At that point, the operator will finish the work piece in progress, then vacate the workstation.

3. Get another turn: Go to the end of the queue.

Plan Your Work FAQs

  • How do I estimate my run-time?

RDWorks has a simulator feature. It underestimates the runtime significantly, so beware. The laser has a simulator feature that is more accurate.

  • What if my single work piece takes longer than the 3-hour session time limit?

You get to keep using the laser until your work piece is done because moving it from the bed would ruin it. That said, be considerate by performing the job during off-peak hours. See the famous Middle Earth Map that took 7 hours at https://talk.dallasmakerspace.org/t/dallas-makerspace-show-and-tell-november-2016/13883/62

  • May I start lasering a new work piece near the end of my session time knowing that it will run over the remaining time?

No.

  • What if I have several work pieces that will take longer than 3 hours total? For example, multiple coasters from a sheet of cork.

Do not send a laser job of multiple work pieces that is longer than the remaining session time. Plan the order of cuts & rasters so you can finish at least one work piece before the session is up. You may go to the end of the queue or return another day. Consider using the lasers during off-peak hours to avoid being interrupted by a queue.

  • Am I obligated to let people “play though” if they say they have a shorter job?

No. That rule has been removed. You have use of the workstation until your session time is up. All members should plan for a wait. Using the lasers during off-peak hours is a way to avoid waits.

No designing. Tweaking OK.

Sessions are for importing your prints, not creating your designs. Tweaking a design is expected. Makespace has other computers available for designing.

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. Join the team and get the skills to do it yourself. Notify us of issues on Talk.

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

Y-axis Disabled.

If a rotary tool user has forgotten to restore the machine, the Y-axis will be disabled during cutting. The image below shows how to reset the machine.
Rotary cutter reset instructions (Y-axis disabled)

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
