The Universal Laser Systems PLS6.150D is a free-standing platform with a materials processing envelope of 32" x 18" x 9" or 5,184 in³ (813 x 457 x 229 mm or 84,950 cm³) that supports dual lasers. As a dual laser platform, the PLS6.150 can support up to two 10.6µ CO2 lasers with a power range of 10 watts to 150 watts. Additionally, it can support a single 9.3µ CO2 of 30, 50 or 75 watts. (if a 9.3u CO2 laser is installed, only one 10.6 CO2 of up to 75 watts may be installed at the same time.)

Ours has two 75w lasers totalling 150w of power.

The unit was donated from SAIC.


  • (2017/05/20) Wiki page created
  • (August 2017) Laser donated from SAIC - thank you, Anna Yu!
  • (12/2/2017) Hooked up to Epilog air and exhaust connection. The air assist works but does leak using the quick connect fitting, the other fitting requires a 1/2" (I think) screw fitting which will create a better seal. The x-axis is off by ~3/8" , y is off too but didn't measure.

Current status: connected to exhaust and compressed air using the ones designed for the Epilog while the Epilog is out of service. Figuring out authorizations. If you want to be part of that, get in touch with CNC Area Host or folks on the Danger Committee.


Authorization for the laser is not viral, meaning you must seek out a Volunteer Authorizer. Please post on the Google Group email list or contact cnc-auths@pumpingstationone.org; look for a recent thread about laser authorizations and post there.

Danger Committee folks from the other laser systems should consider themselves on the Danger Committee for this bad boy, too. Let's get this thing in regular rotation, stat!

Setting Up Your Computer

Air assist

  • Turn on the air assist by flipping the switch dangling from the board behind the laser.
  • Air assist is used for vector cutting to have nice traces and avoid your material to burn. However some people like to have it disabled for raster jobs.
  • Turn air assist off when you've finished and you don't need it while doing your settings.

Water Trap

  • Check the WATER TRAP adjacent to the regulator for accumulated water from time to time. Place a container (and maybe some paper towels) under the regulator and vent accumulated water from the bottom using the small petcock. If too much water accumulates in the regulator, it may flow through the air hose and into the machine, spraying onto the bed/material.

Powering On Machine

  • Turn on the Power Switch and let the machine complete the entire boot up cycle, approximately 1-2 minutes.

Powering Off Machine

  • Allow the Exhaust & Air Assist to run for approximately 10-15 after completing a job. (DO NOT CYCLE THE EXHAUST SYSTEM RAPIDLY).
  • Turn off the Exhaust & Air Assist FIRST
  • Power down the machine
  • Clean up you materials, throw away scrap, make sure the focusing tool is replaced

Laser Materials


Banned Materials

PETG, PET Along with other emissions, is known to emit Benzene which is known to cause cancer.
Polystyrene Known to emit styrene fumes.
ABS Emits cyanide gas and tends to melt.
PVC Emits chlorine gas during a cut.
Bending Plywood Bends into the path of the laser carriage during operation.
Tropical Hardwoods A lot of tropical hardwoods have toxins in the wood.
Corian Creates a fine grit inside the laser bed and will grind down equipment.
Casting Wax Melts a lot.
Nylon Emits toxic fumes.
Vinyl Emits chlorine gas during a cut
Delrin Along with other emissions, is known to emit Benzene which is known to cause cancer.
Foamcore Foamcore is an expanded polystyrene and is known to emit styrene fumes when cut.
