A re-posted snippet for those who are now guessing as to the
functionality of the laser cutter water flow-rate interlock.

But the flow rate is still not what we expected. It was 3.3 L/min when I
installed the sensor, and it currently trips out at 2.0 L/min, but only
if it gets a low reading for three seconds in a row. (I've been turning
this down on an almost daily basis, and I'm not comfortable with that.)
Rob saw it dip to 1.5 L/min. So as annoying as it is to have the laser
drop out during a job, I'm reluctant to keep turning down the trip level
without an explanation.

It was hovering around 2.5 L/min at 6pm tonight, which is the level at
which the light begins flashing to warn you that there is an issue, so
as not to surprise you with an unexpected drop-out midway through your
job.

So yes, there is an issue. All the time. Hopefully this will be solved
shortly!

Have fun,
Darren
