Make sure the Laser Control Computer boots into Windows, it really wants to be a linux box.
Turn on the Laser and dedicated Laser Control Computer via Power Splitter.
HAVE A PATTERN TO CUT (the computer has internet and a couple of programs for editing images) To protect your health and the life of your machine, always obtain a MSDS for materials about which you are uncertain.
Material Safety Data Sheets are an invaluable resource for laser engravers.
Some materials are quite toxic when burned and the damage to your health is much more important than the minor damage you might do to your machine.
A more important consideration are the potentially hazardous fumes that might be released from processing these materials.
Performing this once or twice will likely not drastically damage your machine however, continued engraving or cutting of this material will corrode the inside of your machine.
If you don't know what's in the material you're engraving or cutting, you may have unintentionally cut or engraved items containing polyvinyl chloride.
What happens if you engrave or cut something containing hydrogen or vinyl chloride?.
The big red E-STOP button is there for a reason.
Replacement laser tubes are $300 a piece.
>20mA will drastically shorten the lifespan.
DO NOT run the laser at greater than 15mA.
Do Not Adjust The Current via the Control Knob.
Add to that the fact that this is an infrared laser, which means the beam is invisible, and it falls more along the lines of an angry radioactive cobra. Class 4 means that a coherent reflection can cause "DEVASTATING AND PERMANENT" eye damage with less than 1/100th second exposure, and even diffuse reflections are harmful within a certain distance. If you defeat the magnetic safety interlock switch and run the laser with the case open, then you are exposing yourself to Class 4 Laser Radiation and you deserve what you get.
As long as the safety mechanisms are working the laser is perfectly safe.
Treat the Laser Cutter like an angry cobra and you should be just fine.
Maximum Power Requirements: 660W (main laser unit only excludes water pump/fan/computer/ accessories) Maximum material thickness: 2.75" (with Z table removed and 2" FL lens, 3.25" with optional 1.5" FL lens)
January 31 2012, 7:00pm - 9:00pm: Laser Cutter Class - Learn to use our Laser Cutter!.
I (and whoever wants to help) will do the laser cutting of the 123D Make models that kids doing the 3D Modeling camp at Sci-Quest are making.
On Wednesday, July 18th and Thursday, July 19th I will need to reserve the Laser Cutter all night.
