Drip Governor - A most valuble first hack

[nka]

Electronic valve seems the best way to go for it. But I would keep the mic input to monitor if everything goes as it should.

I agree on keeping the mic monitor, since the computer needs some kind of feedback on the z-position.

Having an additional on/off valve would benefit from the valve itself listening to the drip sensor as well as the "laser on" signal, so it can simply cut the water off if the laser is "on" for more drips than it would take for one layer (or one sublayer) until the laser is "off" again for long enough to indicate that the sublayer is done. Just having "Laser On" equal "Valve Off" is a pretty simple way of doing things on the hardware side, but it would slow down prints during simple layers, though .
