The Epilog Laser Cutter is an Epilog 60W CO2 laser cutter and engraver located in the Fabrication Lab. It can engrave and/or cut sheets and boards of a variety of materials, typically paper, cardboard, wood, and some plastics. (Always refer to the #Material Compatibility List for the Laser Cutter-Engraver before cutting or engraving.) It can also engrave on glass. To engrave on cylinder-like objects, use the rotary attachment.

The Laser Cutter is treated as a printer by the imaging software. A range of software can be used. Here's a short list of typical software.
For Raster Images
- Gimp (free software) Gimp Download Information
- Adobe Illustrator
- (An old but legally free version of Adobe Photoshop can be downloaded: Adobe Photoshop CS2 )
For Vector Images
- Adobe Illustrator
- Inkscape (free software) Download Options for Inkscape
We have a "Rim-Drive Rotary Attachment" that is for use with our laser cutter.
The rotary tool is used for engraving round materials like bottles, glasses, or any other cylindrical item up to 11.25″ (286 mm) in diameter.
When plugging in the "Rim-Drive Rotary Attachment" for use, make sure the main power (big rocker switch on front right of the Epilog) is OFF first. Failure to do this will damage the electronics and void the warranty.
Using the Laser Cutter
In order to use the laser cutter, you must be a member of FamiLAB. You must also be certified to use the laser cutter. Becoming certified involves taking a Beginner Laser Class ("Laser 101").
Using the laser cutter is fairly simple and safe if proper usage precautions are taken. These precautions include some basic steps that are important for using the laser cutter.
Four of the first steps are the following:
- Make sure the AC is on and lower than 80ºF as the laser cutter needs to be kept cool. The laser cutter should never be used when the temperature is near, at or above 90ºF.
- Make sure the exhaust fan is on which pulls the air from the laser cutter. Use the black colored light switch to the right of the laser cutter to turn it on or off.
- Make sure the Air Assist is on next to the laser cutter.
- Make sure the laser cutter is on.
Important: Read the Laser Rules before using the laser cutter.
In the event that the laser doesn't work properly or is making odd sounds, contact the Laser Cutter Point of Contacts (POC). Also, make it known on Slack in the #laser channel. It needs to be reported so it can be fixed.
Before engraving heavy objects (over a couple pounds), remove the vector grid. Heavy objects will damage the the grid.
Different results can be accomplished by adjusting the speed and power of the laser.
Laser 101 Class
For those interested in using the laser cutter there's a beginner laser class called "Laser 101 Class", which is held occasionally. Check the FamiLAB Calendar for when it's scheduled.
If you wish to take the class ask in #laser on Slack and we will get you scheduled.
The class normally includes two parts.
- Presentation focused on safety and precautions using the laser cutter.
- Hands-on example of how to use the laser cutter. Each person will be able to use the laser cutter using Adobe Illustrator.
At the end of the class each person will be certified to use the laser cutter provided they're a FamiLAB member. Additionally, each person will be able to keep a small cut and engraved item which they made.
Material Compatibility List for the Laser Cutter-Engraver
Most of this information on material compatibility comes from Epilog's website with other information from a range of resources regarding laser engraving and cutting.
The alphabetical list below are materials that are safe or NOT safe to use on the laser cutter/engraver.
If the material isn't listed here contact someone on the "Point of Contact" list and ask.
|Bare Metals (See note #1 below)||Note #1||No|
|Brass (See note #1 below)||Note #1||No|
|Foam (Most formulations)||Yes||Yes|
|Formica (Read Note #7 Below!)||-->No!<--||-->No!<--|
|Leather (Veg-Tanned Only) (Read Note #6 Below!)||Yes||Yes|
|MDF Board (Read Note #2 Below)||-->No!<--||-->No!<--|
|Mother of Pearl||Yes||Yes|
|Neoprene (Read Note #4 Below!)||-->No!<--||-->No!<--|
|Polystyrene Foam (Read Note #8 Below!)||-->No!<--||-->No!<--|
|Printed Circuit Boards (PCBs) (Read Note #5 Below!)||-->No!<--||-->No!<--|
|PVC & Vinyl Based Plastics (Read Note #3 Below!)||-->No!<--||-->No!<--|
|Rubber (Most formulations)||Yes||Yes|

|Titanium (See note #1 below)||Note #1||No|
- Bare metals, Brass, Stainless Steel, Titanium: CO2 lasers will mark bare metals when coated with a metal marking solution.
- MDF Warning: MDF is typically made up of 82% wood fibre, 9% urea-formaldehyde resin glue, 8% water and 1% paraffin wax. It's the formaldehyde resin glue that's dangerous when heated and poses a considerable health risk. It can be used in the laser, but please use only in moderation.
- PVC Warning: Under NO condition should the laser be used with PVC (PolyVinyl Chloride) material. Using PVC with the laser will give off hydrogen chloride gas which can kill you. It will also damage the laser and void the warranty.
- Neoprene Warning: Under NO condition should the laser be used with Neoprene. Notice that under hazardous combustion products, the MSDS for Neoprene indicates hydrogen chloride is emitted when the material is heated.
- Printed Circuit Boards should not be used with the laser. Information from the Epilog website states that PCBs should NOT be used with the CO2 laser.
- Chrome Tanned Leather will give off toxic gases when used with a laser cutter-engraver.
- This material will give off toxic gases when heated and used with the a laser cutter-engraver.
- This material will catch fire when heated and used with the laser cutter-engraver.
- Pine Plywood does not vector cut well in the laser. Birch or Poplar plywoods result in a more superior edge quality at the recommended power settings while still being widely available.
|Important Note About Heating Neoprene or PVC: Neoprene and PVC produce HCl (hydrogen chloride) upon combustion or in use with the laser cutter. At room temperature, it is a colorless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric humidity, the air you breath. Hydrogen chloride forms corrosive hydrochloric acid on contact with water found in body tissue, like in your your lungs. Inhalation of the fumes can cause coughing, choking, inflammation of the nose, throat, and upper respiratory tract, and in severe cases, pulmonary edema, circulatory system failure, and death. Skin contact can cause redness, pain, and severe skin burns. Hydrogen chloride may cause severe burns to the eye and permanent eye damage. Additionally, this gas will severely damage the laser cutter and void the warranty.|
