Hey guys,

I'm pretty sure, Peachy's default dripper system is uncontrolled, at least not by electronics.

Using extreme numbers:
If the water takes 20min to rise 10cm (I guess, that's a fast, but realistic print), you get .5cm per minute and during those 10sec per Layer (see videos) the water will rise about 1mm per Layer.
The Platform being maybe 5cm wide, this gives you 88.5°.
Seems pretty close to 90° to me (As I said before, I think, these are really extreme numbers).
Making the dripper slower (I guess, .2cm per minute is a realistic value) you can get angles as close to 90° as you want.

Greetings,
