6040 Laser Cutter

About

In December 2014 we purchased a new A2 laser cutter from China and a LAOS controller board to upgrade it. The laser was delivered in January 2015 and work is currently underway integrating it into the hackspace RFID system so usage can be tracked. It's anticipated that things should be up and running by mid to late February.

After the upgrade the laser is controlled with Visicut. The configuration for Visicut can be automatically installed (as of Mid Feb 2015) by simply selecting Leeds Hackspace from the list of laser cutters on first installation.

An induction on using the laser cutter is required before use by a designated Hackspace inductor.

Capabilities

There are limits to how thick it can cut, but the laser should cut:

• Acrylic sheet
• Plywood
• MDF
• Paper
• Card (with the exception of corrugated card)

You will NOT cut:

• Vinyl (toxic/corrosive fumes)
• Lexan (different toxic fumes)
• Corrugated card (fire risk)
• Food (it smells horrible and gunges up the laser)

"Etch"-able with a mask on material (covered in induction):

• Metal
• Glass[1]
• Ceramics

All of the above need their reflectiveness dealing with or you could damage the laser.

Anything not mentioned above, ask a Laser-inducted director and do not be surprised/upset when they say "hell no!"
