Large Format Lasers
Rabbit DL-XX-9060 80w
80w CO₂ Laser with Lightburn Control Software
The Setup, Operation, and Cleanup Checklists of this guide are what instructors use to ensure that you can use the equipment according to community expectations.
A laser cutter is used to mark, engrave, or cut a wide variety of materials. They work a lot like printers do, where you send a graphic to print. Instead of ink, the laser uses heat to transfer the image onto the material.
Usage Highlights Large Format Laser Clearance or Class Equivalent Required Before Use
SAFETY CARE CLEANUP 1. Check that your material is safe to use 1. Avoid collisions with the lens carriage 1. Vacuum the interior 2. Listen for the exhaust when the laser powers on 2. Mirrored acrylic must be reflective side down 2. Recycle waste in scrap bins 3. Stay by the laser while it’s running 3. Submit a maintenance request when needed. 3. Empty bins when full
Personal Protective Equipment Face Masks & Cleaning Kits are required at all times during the Pandemic
Lid - Absorbs the laser radiation and must be closed when running a job Exhaust - Allows for the efficient removal of fumes and particulate Maintenance Tag - Manually tracks the usability status with Green/Yellow/Red cards Lens Carriage - Houses the mirror, lens, and air assist Cutting Bed - 1200 x 900mm (~47” x 35”) Consists of a removable, magnetic honeycomb tray. Seated properly, it should feel stable & secure Emergency Stop - Reserved for emergencies. To deactivate and reset, you must twist the spring-loaded knob. Power Switch - Key switch turns the machine on and off Control Panel - LCD interface with commands to operate the laser

FIRE TOXIC FUMES LENS COLLISION Listen for the exhaust. It should automatically turn on with the laser Be mindful of the safety of your cutting material Load material with care Vacuum beneath the cutting bed to prevent flammable build-up Avoid chlorinated plastics and other prohibited material on the list Be mindful when moving the cutting bed to vacuum Avoid foam and other prohibited material Off-gassing dangerous fumes like chlorine and cyanide is always a concern Ensure material is flat and will not collide with the lens carriage during operation Always pause the laser if you need to step away from the machine
MATERIAL DANGER Chlorinated plastics (PVC, vinyl, artificial leather, Moleskine notebooks, polymer clay/Sculpey) Emits chlorine gas Polycarbonate/Lexan Cuts poorly, absorbs laser, discolors, may catch fire ABS Emits cyanide gas, melts, bursts into flame HDPE (milk bottle plastic) Catches fire & melts Polypropylene foam (foam core, Styrofoam) Catches fire Fiberglass Emits dangerous fumes Coated carbon fiber Emits dangerous fumes Pressure treated wood Emits dangerous fumes Galvanized metal Emits dangerous fumes Mirrored surfaces, including uncoated metal Will not cut, reflects laser beam

Initial Setup RASTER VS. VECTOR
Rastered data is an image that is made of pixels. Much like an inkjet printer, the laser will scan the artwork on a scale from black to white. The laser will vary the number of dots it fires depending on the tone of each pixel.
Common file formats like .jpeg, .gif, and .png are all rastered data.
Vectored data is made of paths that form lines and shapes. They contain mathematical data that allows the laser to trace the path like following coordinates on a map. This allows the laser to cut or score a line as well as etch a filled shape.
Common file formats like .ai, .dxf, and .svg are all vectored data.
Power on the laser Import your file into Lightburn Set the job origin in Lightburn Check the layer mode Adjust the speed and power settings Send your file to the Laser
Lightburn accepts a range of file formats.
Supported vector files: .ai .pdf .dxf .svg .lbrn
Supported image files: .jpg .jpeg .png .tif .tiff .bmp
Import your file into Lightburn.
Set the job origin. Check the layer mode: fill—fills a vector shape to etch line—traces along a vector line images—will only etch and optimize for a rastered photo
Adjust the speed and power settings.
Send the file to the laser, keeping the filename “LIGHTBRN”. This saves over old job files and helps maintain a manageable memory in the machine’s job queue.

Listen for the exhaust to ensure that it is on Check that your material is safe to cut Load material Focus the lens on your material Set the origin on the laser Check the footprint of your job Start your file Monitor the machine until the job is complete and cleanup
FOCUSING THE LENS
Select on the control panel
Use to align the lens carriage to the focus gauge
Select to return to the main menu
SETTING THE ORIGIN
Use to jog the lens carriage to the desired location
Optional: to verify the exact location
Select to set
Select to check the footprint (framing can also be managed from Lightburn control)
CLEANUP CHECKLIST Power off the Laser Reset any modified computer settings to default Vacuum the interior so material does not build up beneath the honeycomb Note any maintenance needs or concerns on the tag and at protohaven.org/maintenance Recycle waste in the single-stream scrap bins Empty the bin when full
There are two black scrap bins reserved for laser waste. Maintaining these is a shared, communal responsibility.
When you notice the scrap bins are full, it’s time to take it to the dumpster out back. Feel free to enlist a helping hand.
If you notice valuable material while emptying the bins, use your judgement to selectively save a few pieces or take it home for your personal use.
Update the physical Maintenance Tag at the machine Green can be used without issue Yellow can be used with caution Red cannot be used without hazard to either the user or the equipment Record issues at protohaven.org/maintenance. This notifies our staff and volunteer maintenance crew of any issues
Common Issues Possible Causes Resolutions Cut does not go through the material The speed is too fast or the power is too low Use a scrap piece of the same material to make a series of tests with incremental adjustments until you find the sweet spot The lens or mirror is fogged Alert the staff or volunteer on duty to the issue Slop in the frame
The origin in Lightburn is not set appropriately Adjust the origin point in Lightburn The artwork is too large for the cutting bed: 1200 x 900mm (~47 x 35”) Adjust the overall artwork size Burn marks on the back of the material Hot debris is scorching the edges of the cut lines Lay a sheet of paper beneath the material and the bed or line it with a laser-safe vinyl free tape
Register your material on the cutting bed using magnets or tape when doing a production run.
Use the front pass-through door for extra long pieces.
Use surface treatments like Cermark or paint to etch designs onto metal surfaces.
