Maximum Overhang?

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.

Ohh napking math time ...
here is how I would do it.

we have 100 layers per mm so each layer we move up 0.01 mm, and standard .7mm laser spot size ... lets say we need to over lap the spot by 75 percent each layer to make sure the layers connect( this is very untested)
so every 4 layers we move .7 mm over and .04 mm up and Im feeling lazy so ill go here http://www.cleavebooks.co.uk/scol/calrtri.htm
I get 86.7 deg

wow our napkin math answers are very close quertz!

here is a pick of a rook printed with the standard v1 kit printer:

The rook has stairs that have rather flat tops:

With the flat tops lit just right from behind, and a macro lens we can see what appear to be layers!
seeing individual layers is very rare... sometimes we see artifacts that look like layers but are some other effect like break over. In most situations our layers are to small for the human eye to see:

PS that last pic is my favourite peachy ever
