Reprap Prusa i3 (Marlin firmware) bed auto level setup and installation
Start by looking for parts for auto level setup. Hardware you need are hobby servo and end stop.
Image will show you the servo output pins, which is D11, 5V and GND (AUX-1 pins)
Since I have not done this my self yet, I will link next parts from Youtube user ZenmasterM here.
I will do this in near future for my Prusa i3 too and I make detailed instructions with images!
