Code on [https://github.com/munichmakerlab/LaserSafety github]
The Safety System runs on an Arduino, checks for
* Water flow (Right before the laser tube, arduino counting pulses)
* Chiller temp (measured before and after laser tube)
* Exhaust system (differetial pressure; digital)
* water leak under the chiller and in connection pipe on both sides (digital) (--> Heiko)
* lid closed (reed contacts, directly connected to the controller --> Peter)
--> Adrian, Heiko (Code review by Peter?)
Maybe later:
* Compressor running
* power consumption (???)

Our laser tube:

Mirrors:
* use copper-backed or molybdenum-backed mirrors. Do not use silicone backed mirrors.

When we have this thing running, we maybe need to think how we can get the costs back in. A 100W laser tube costs around 1200€ and has a lifetime of 6000-10000h.  
A 100W laser tube costs around 1200€ and has a lifetime of 6000-10000h. On the [[20150315 Plenum]]/[[20161009 Plenum#Commercial_use_of_the_laser_cutter|20161009 Plenum]]), it was decided that the following usage fee will be charged:
 
* 2€ per 10min for members, 4€ for non-members, 5€ for "commercial" use
As discussed on the [[20150315 Plenum]] (and again in [[20161009 Plenum#Commercial_use_of_the_laser_cutter|20161009 Plenum]]), we will start with the following structure:  
* 2€ per 10min for members, 3€ for HuS, 4€ for non-members, 5+€ for "commercial" use
 
== Logging ==
We installed a data logger to keep track of the usage hours. The logger tracks the time the air assist is on, which is just about the runtime the laser controller displays for a job. We want to use this to track the working hours of the laser tube, but if you want to check how long your laser cutting jobs took, feel free to checkt that here as well:
