Rabbit Large Format Laser Tech Checklist
Use
Start Up
- Import your file into Lightburn
- Set the job origin in Lightburn
- Check the layer mode
- Adjust the speed and power settings
- Power on the laser
- Listen for the exhaust to ensure that it is on
- Check that your material is safe to cut
- Load material – if it moves or is bowed, use hold-downs
- Focus the lens on your material. Make sure it won't hit hold-downs or material.
- Set the origin on the laser and check that the Lightburn job start is set accordingly.
- Check the footprint of your job
- Start your file
- Monitor the machine until the job is complete and cleanup
Cleanup
- Vacuum the interior so material does not build up beneath the honeycomb
- Power off the Laser
- Close Lightburn & don’t forget your USB!
- Note any maintenance needs or concerns on the tag and at protohaven.org/maintenance
Consult the main page for more information.
Maintenance & 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 |
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. |
Other potential problems
Layers have too many/not enough passes | Part set to wrong layer color |
Layer may not be set to output | “Cut selected shapes” or “Start from selection origin” may or may not be selected |
Start point is set to “Absolute Coordinates” instead of “User Origin” or “Current Position” | The outside of a shape is cutting before inside cuts (leading material to drop out of focus) |
Cut is too close to hold-down |
- One of the most common issues is the lens and mirror get dirty after frequent use
- The laser may also be bumped out of alignment. Test this by checking a shape near the rear left of the bed (closest to the laser tube) and the front right (furthest).
Safety
Never leave the laser while a job is running!
Common Hazards
- Fire
- Toxic Fumes
- Lens Collision
Check to make sure the material is acceptable.
- Generally, plywood up to ½ inch thick and acrylic made for laser cutting are acceptable.
- Cardboard, paper, leather, and fabric can be cut but should be watched carefully.
- Vinyl, PVC, and HDPE (#2) can’t be cut, nor can metals. Plastics and coated materials are generally prohibited. Please consult the full list with questions.
