Plen2 with 9g servos
Hai,
I really love beautiful design of robot Plen2
I want to print a self Plen2 with my Prusa I3 and want to use 9g servos, the stl files I have found through Plenza
https://github.com/BinarySpace-Hackerspace/plenza
But I think all stl files are not present
I have two vraagjes
1; which pins are used by the Arduino Mega for intput and output, where can I find such data
2; how you connect the arm to the hand (system of 9g servos ) i find not a piece for do that
Kind regards

Re: Plen2 with 9g servos
Hi, Sembot.
Firstly sorry to say we moved the category of this topic, but we thought more accurate that there is the post in this category.
1; We have confused why they are using Arduino Mega. (We are using Atmega32u4, it's not Arduino Mega.)
However, it's easy that you are porting Atmega32u4's firmware to Arduino Mega (Atmega2560).
Please connect servos through 3bit multiplexer x3, and signal sauce lines connect to Digital pin 11, Digital pin 12, and Digital pin 13.
Bit-select pins connect to any Digital pin x3 you choose. (You must modify Pin.h, s.a. : https://github.com/plenproject/plen__fi … ware/Pin.h)
2; In that repository, some *.stl are merged we think, so you have got everything you need.
