LAOS Laser

Hello!

I am currently switching our DIY Lasersaur-based Lasercutter to LAOS. I have completed building a rev.4 board and display board, all working nicely so far. But some issues/questions:

- Interlock
Interlock/Lid switch implementation is mentioned in the forum, but I cannot figure out if it is implemented in any way or where it would be hooked up to the LAOS board. This is not only for security, but also for "Auto-home after lid is closed" etc.

- There are optocouplers on some of the in- and outputs, which is great, but we only have a single 5V supply within the lasercutter. What is the suggested method to seperate the two "sides" of the optocoupler for them to do their thing? If I just hook them up to the same supply they will not protect the circuit from peaks or noise from the laser as the 5v connection is still shared. Of course I could always add some more filtering...

- The current build instructions only mention building using GCC4MBED. Is this version now fully operational, or is there any reason to compile it with the horrible mbed.org online compiler thingy?

- Is there any progress on http://redmine.laoslaser.org/issues/36 ? Our laser does not have any hardware way to control laser power, so working PWM is an absolute must for our laser to be usable at all.

Thanks for your help, looking forward to completely switching over to LAOS and VisiCut, much better than our current setup.
