- As of 5/15/2014 CURRENTLY WORKING
- As of 4/29/2015, not working, we're on it, someone (Jason S.) has sent in the laser tube for warranty replacement. Epilog claims it sent the part for delivery by 5/4/15.
- As of 3/23/2015, not working, we're on it, someone (Jason S.) is going to troubleshoot and get parts on order tonight, ASAP. Please do not attempt to use in the meantime.
- As of 3/24/2014, parts needed have been identified and are ordered, were under warranty, should arrive by 3/26/2015, and are expected to be installed that evening.
- Don't use the autofocus, because it could burn out a motor.
- Don't cut materials that will ignite or emit dangerous fumes (any chlorinated plastic like PVC, for example). See section below.
- Always use the exhaust fan/always use the air assist on vector cuts.
- You must stay with the job; don't walk away. Things could catch on fire, that would suck.
- Sometimes it's a pain to get the right driver working. http://www.thinkgeek.com/product/11c3/
- Do not attempt to service the machine yourself unless you've cleared it with Elizabeth
- Do not touch any settings in the Config menu on the machine itself
- Do not touch any settings in the Maint menu on the machine itself except you may use Maint/1/Return Home to reset the cutting head to the machine's default origin (.015" inside the top left corner as of 4/28/15)

Experiment with settings to find the lowest possible power and highest possible speed to get clean vector cuts. The new optics and tube (as of December 2014) can cut many organic materials with a minimum of charring.
Always turn on the exhaust fan using the switch located in the silver box to the left of the machine.
Turn on the air assist by turning the silver knob on the regulator located on the red bracket attached to the left of the machine. The pressure regulator has no adjustable settings. It is either on or off.
Air assist is used for vector cutting to have nice traces and avoid your material to burn. However some people like to have it disabled for raster jobs.
Turn air assist off when you've finished and you don't need it while doing your settings.
Check the regulator for accumulated water from time to time. Place a container (and maybe some paper towels) under the regulator and vent accumulated water from the bottom using the small petcock. If too much water accumulates in the regulator, it may flow through the air hose and into the machine, spraying onto the bed/material.
Please leave the machine cleaner than you found it by emptying the crumb tray below the cutting table, picking up cutouts, and vacuuming up any acrylic dust you made.
NEVER CUT THESE MATERIALS
- PVC (Poly Vinyl Chloride): Also known as "vinyl" "pleather" or "artificial leather." Most adhesive vinyl shelf paper (e.g. Con-Tact Paper) also is PVC. Emits HCl and nasty chlorinated compounds when cut! Don't ever cut this material as it will ruin the optics, cause the metal of the machine to corrode, and ruin the motion control system.
- Polycarbonate: Also known as "Lexan." Polycarbonate is also often found as flat, sheet material. The case cover window on the laser cutter is made of Polycarbonate because polycarbonate strongly absorbs infrared radiation! This is the frequency of light the laser cutter uses to cut materials, so it is very ineffective at cutting polycarbonate. Polycarbonate can also emit flame and chlorine gas when cut, making it a poor choice for laser cutting.
- ABS: ABS does not cut well in a laser cutter. It tends to melt rather than vaporize, and has a higher chance of catching on fire and leaving behind melted gooey deposits on the vector cutting grid. It also does not engrave well (again, tends to melt). Finally, ABS emits cyanide when cut.
- HDPE: "milk bottle" plastic. It melts. It gets gooey. It catches on fire. Don't use it.
- PolyStyrene Foam: It catches fire, it melts, and only thin pieces cut. This is the #1 material that causes laser fires!!!
- Fiberglass: It's a mix of two materials that can't be cut. Glass (etch, no cut) and epoxy resin (fumes)
- Coated Carbon Fiber: Again, it's a mix of two materials. Thin carbon fiber mat can be cut, with some fraying. However, once coated with epoxy it will emit noxious fumes.
- Silhouette magnet paper (sold by Inventables by example): it likely contains chlorine. Emits HCl and nasty chlorinated compounds when cut! Don't ever cut this material as it will ruin the optics, cause the metal of the machine to corrode, and ruin the motion control system.
- PTFE:, also known as Teflon or any fluorinated polymer it will releases nasty fluorinated compounds (bad for you) and sublimate then deposit on the lenses (likely destroying them).
- Gator foam: foam core gets burned and eaten away compared to the top and bottom hard paper shell. Not a fantastic thing to cut, but it can be cut if watched. And the MSDS sheet says it may produce hydrogen bromide and hydrogen chloride known to degrade the optics and mechanic of the cutter
- Any other plastic with "Chlor" or "Fluor" in the name, for the same reasons as PVC and PTFE above.
Test for material
Some people came up with an easy protocol to help identify unknown polymers: Nyc Resistor - how to identify polymers with burnination. We don't know how reliable it is. And we can't but recommend to do that under good ventilation (outside?)
The laser can cut or etch. The materials that the laser can cut materials like wood, paper, cork, and some kinds of plastics. Etching can be done on almost anything, wood, cardboard, aluminum, stainless steel, plastic, marble, stone, tile, and glass.
- Many woods up to 1/4" thick. Composite woods like plywood contain glue, and may not laser cut as well as solid wood. Engineered woods like MDF are okay to use but may experience a higher amount of charring when cut. Be very careful about cutting oily woods, or very resinous woods as they also may catch fire.
- Paper cuts very very well on the laser cutter, and also very quickly. Thin paper and single layer card stock and cardboard are perfectly OK. Thicker cardboard, carton, and other papers also cut very well but need to be watched to make sure they don't catch fire.
- Cork cuts nicely, but the quality of the cut depends on the thickness and quality of the cork. Engineered cork has a lot of glue in it, and may not cut as well. Cork thicker than 1/4" should be avoided.
- Cast acrylic (also known as Lucite, Plexiglas, PMMA) cuts extremely well on the laser cutter, leaving a beautifully polished edge. With care, acrylic material up to 1/2" thick can be cut on the laser cutter. Extruded acrylic cuts less well and etches even worse. It tends to melt and puddle rather than vaporize.
- Delrin (POM) in thin sheets cuts and engraves very well. Delrin comes in a number of shore strengths (hardness) and the harder delrin tends to work better. Great for gears! It is possible to deeply engrave Delrin to make dies for embossing paper and leather.
- Kapton tape (Polyimide) : Works well, in thin sheets and strips like tape. 1/16" thick is about as thick as you can cut reliably.
- Mylar : Works well if it's thin. Once you get too far past 1/16" thick mylar has a tendency to warp, bubble, and curl. Gold coated mylar will not work.
- Solid Styrene : Smokes a lot when cut, but can be cut. Keep it thin (1/16")
- Depron foam: Used a lot for hobby, RC aircraft, architectural models, and toys. 1/4" cuts nicely, with a smooth edge. Must be constantly monitored when cutting.
- Cloth (leather, suede, felt, hemp, cotton, polyester, but NEVER vinyl or pleather-- see above) They all cut well. Leather is very hard to cut, but can be if it's thinner than a belt (call it 1/8")
- Magnetic Sheet material cuts beautifully (make SURE it does NOT contain chlorine, see above)
- NON-CHLORINE containing rubber is fine for cutting. Natural rubber engraves but leaves a dark sticky residue that doesn't affect stamps if the piece is engraved deeply enough.
- Carbon fiber mats/weave that has not yet had epoxy applied can be cut, very slowly. You must not cut carbon fiber that has been coated!!
- Etching: all the above can be etched, in some cases very deeply. In addition, you can etch:
- Glass (green seems to work best) .. looks sandblasted. Only FLAT GLASS can be engraved in our cutter. No round or cylindrical items.
- Ceramic tile
- Anodized aluminum ( vaporizes the anodization away )
- Painted/coated metals ( vaporizes the paint away )
- Stone : Marble, Granite, Soapstone, Onyx. Gets a white "textured" look when etched
There is an expensive coating called 'cermark'. This marking compound costs $100 for a small bottle, and must be diluted with ethanol and applied to metal (not ceramics or stone) before being etched to leave behind a permanent dark black mark.
- Inventables for acrylic
- Abbey Specialties for acrylic in varied sizes, this company is our landlord. They are in the other half of our building and if you ask they can drop off in our shared loading dock.

Notes on Software Compatibility
Adobe Illustrator and the epilog drivers don't always work great together. If you're experiencing any of the following, there is a simple fix:
- Job runs, but it's an empty run. Laser head moves once then completes, even though raster vs vector is correctly configured and stokes are set to 0.072pt.
- Updating the media size in the epilog print driver does not update the size in Illustrator's print dialog, unless you reopen settings and press 'OK' in epilog again another time or two.
- Open pressing print in Illustrator, you get a message about "nothing to print in selected layers" or similar.
- Media size entered in epilog driver is read as the reverse by Illustrator (e.g. 24x12 is seen as 12x24 by Illustrator)
It seems epilog's driver doesn't play nicely with Illustrator, and Illustrator interfaces with the print driver a lot because it micromanages a lot of things. If your document is saved as a .AI with PDF compatibility, simply right-click your AI file and open with Adobe Reader instead of Adobe Illustrator, and print from there.
Adobe Reader has a much more "dumbed down" print dialog that just works with Epilog's driver. You don't have to resave your .AI as .PDF, as Adobe Reader can read .AI files saved in compatibility mode (that's the default).
NB: Always return the machine back to the default configuration with a cutting bed after use.
Do not attempt to install the rotary attachment without ensuring that the cutting head AND autofocus plunger will clear it. It is extremely easy to damage the autofocus plunger and/or crash the head in the Y dimension, which will burn the motor out and make a lot of people sad.
- Turn machine on
- Disable X/Y
- Open front cover
- Lower bed almost to the bottom of the machine while still allowing the catch tray to be removed
- Turn machine off
- Flip up rulers and remove cutting bed
- Remove slide out catch tray
- Install the attachment locating it in the 3 holes in the bottom of the bed DO NOT CONNECT PLUG YET
- Make sure the Y axis will clear the top of the attachment, if it will not turn the machine on and lower the bed further making sure to turn it off afterwards
- Connect the attachment cable to the connector in the back of the bed
- Turn the machine on - the machine will zero home over the top of the attachment
Reverse steps to uninstall.
- DO NOT USE AUTO FOCUS
- 0,0 is TOP LEFT
- Y axis is wrapped around the piece
- Set Y size to circumference of piece - measure with soft tape or string/ribbon/etc
- Make sure to set print size in driver to same as art board in illustrator

Front door interlock broken
The front door interlock has two reed switches. The one on the right isn't being activated by the factory magnet so it currently has an additional magnet on the inside of the machine, right to the left of the switch
List of Currently Certified Users
This list is hugely incomplete because nobody was doing it. Someone should fix that eventually... for now, new certs should go in here. If you are certified and remember who certified you, go ahead and add yourself. Your non-presence on this list is not intended to insult you or your relatives.
