Lasers: Exciting!

Also, dangerous.

Only safety-conscious adults with proper safeguards should operate lasers of any kind.

CO2 Lasers

LI40.jpg

Hyrel offers a 40w CO2 laser on some of our Hydra models.

We recommend at least 500 cfm (850 m3/h) of exhaust while lasering.

Hyrel Specific

Settings

Your acutal laser controller, on the Aux Heads tab, should be set to "Laser_40".
Your safety/mirror/lens controller, on the Heads 1-5 tab, should be set to "CO2_Laser" or the newer "CO2_Lens".

Z-zero should be set 8 mm from the bottom of the focusing lens hardware for the CO2 laser.
