Ok,, so I've dealt with 50+ laser modules by now. I've had a recent string of 1/2 watt UV lasers (7 of them so far) that do great on all these little test runs. I go to do an eight hour engraving and the laser dies about 20 minutes in. Seems like it's the actual diode that dies. 3 different suppliers so far.

What they say is let the laser sit for five minutes every 30 minutes of running. doesn't account for the 20 minute lifetime of the recent lasers.

My question is,, can we add an auto pause to the program?? Is there an elegant way to do it??
