  * Manual: [[:start|Download]]
  * Clearance Required: [[tools:laser_rabbit:clearance|Rabbit Laser Proficiency Based Clearance]]

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.

The [[#tool_safety|Tool Safety]], [[#tool_care|Tool Care]], [[#laser_operation|Laser Operation]], section of this guide are what instructors use to ensure that you can use the equipment according to community expectations.

====== Requirements ======

[[:start|Large Format Laser]] clearance or class equivalent is required before use.

====== Warnings ======

🚫 Do not use any of the prohibited materials\\
⚠️ Stay by the laser while it’s running

See the [[#tool_safety|Safety Section]] for more information.

====== Tool Safety ======

=== Personal Protective Equipment ===

==== Common Hazards ====

^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!**

====Prohibited Materials====

^ 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|

===== Inspection =====

Before you start using the tool you are expected to do an initial inspection and assess its readiness for use.\\
===== 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 Setup===
{{tools:large_format_laser_tool_tutorial_image18.png|300}}
Lightburn accepts a range of file formats.

Supported vector files: 
.ai .pdf .dxf .svg .lbrn

Supported image files:
.jpg .jpeg .png .tif .tiff .bmp

  - {{tools:large_format_laser_tool_tutorial_image11.jpg |200}} Import your file into Lightburn.
  - {{tools:large_format_laser_tool_tutorial_image1.png |200}} Set the job origin.
  - {{tools:large_format_laser_tool_tutorial_image9.png |200}} 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.
  - {{tools:large_format_laser_tool_tutorial_image12.png |200}}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.

===Common Cut Settings===

===== Operation=====

  - 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 Z([[#Control Panel|Control Panel 2]]) to change to bed height control.
  - Use ↔ [[#Control Panel|Control Panel 1]] to align the lens carriage to the focus gauge (Right raises bed, left lowers)
  - Select Esc([[#Control Panel|Control Panel 3]]) to return to the main menu.
====Setting the Origin====
  - Use the directional arrows([[#Control Panel|Control Panel 2]]) to jog the lens carriage to the desired location.
  - Optional: Press Pulse([[#Control Panel|Control Panel 8]])to verify the exact location.
  - Select Origin([[#Control Panel|Control Panel 5]]) to set the Origin
  - Select Frame([[#Control Panel|Control Panel 6]]) to check the footprint of job. (framing can also be managed from Lightburn control)


===== Cleanup=====
  - 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


===Scrap Breakdown===

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. 

==== Maintenance Requests ====
If you encounter any of the issues listed in the Inspection area or have any other issues with the tool not working properly:

  * Update the physical Maintenance Tag at the machine
    * 🟢Green can be used without issue
    * 🟡Yellow can be used withcaution
    * ⛔Red cannot be used without hazard to either the user or the equipment
  * Record issues at [[https://protohaven.org/maintenance|protohaven.org/maintenance]]. This notifies our staff and volunteer maintenance crew of any issues.

===== Troubleshooting =====

^Problem ^Likely Cause ^Potential Solution^
|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|
|No visible cutting happening| Lid safety switches not engaged, or software issue|Confirm the lid safety switches click when the lid closes. Turning the machine off and on again may also help if that isn't the problem.|

===Special Setups===

  * 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.
