The relay was my first idea, but it turned out pretty quickly that there are no such relays that could be driven directly by Mesa card - even those with 5V coils on control side would require too much current for gpio pin to sink - I think that smallest I found was around 100 mA. I just wanted to tell that I resoldered optoisolator and now it is kind of working correctly. Laser is shining. The problem is that it is not burning the wood. Is the voltage drop in the wiring too high? How can I help there - use thicker wire leads?
