How to use this laser cutter
- You must be trained on this LASER before using it. Get trained by taking the class!
- Detailed Checklist for Big Red: http://goo.gl/agZeub
- Simplified Checklist for Big Red: http://goo.gl/jM9vem
- i3 Detroit has a similar laser cutter and a very nice wiki: http://i3detroit.org/wi/index.php?title=Laser_Cutter_-_Bumblebee
- Their power/speed settings won't correspond with ours, as their cutter is 150 watt, this one is 80.
$.75 a minute of actual laser time - public $.50 a minute of actual laser time - members
- When running an outline of a Moai head, the laser stopped and started at various points for a very brief moment.
- We simplified the outline in inkscape and made sure to unite lines in lasercut 5.3. This helped, but we still stop/start problems with the laser.
- It appears that if your image/vector file is greater than any dimension of the bed (140cm * 90cm), the software will crash upon opening.
Occasional divets noticed when cutting through acrylic
Material: 3mm Clear Acrylic
- Divet pattern may correspond to honeycomb outline. Suggestions:
- Mentions reflection issue from honeycomb: http://www.sawmillcreek.org/showthread.php?199099-Knife-table-verses-honeycomb-table
- Utilizes a different cutting table method: http://www.kernlasers.com/PDF/Magazine%20Articles/Laser%20Engraving%20on%20a%20Larger%20Scale.pdf
- Mentions proper adjustment of beam as a means of reducing relflection: http://leadershipdilemma.net/tag/5-essential-tips-for-cutting-acrylic-sheets-with-laser/
- Mentions reducing power and cleaning your grid: http://www.sawmillcreek.org/archive/index.php/t-205172.html
- Suggests leaving the backing material on your acrylic (possible just back side)
- Nick suggests just putting a piece of paper on the back side
- Divet Pattern seems to be reduced when:
- Leave adhesive material backing on Acrylic
- With 3mm cut at 25% Speed 100% Power.
- Do a test circle or line first with your material to verify.
