Introduction

This project is setting for RepRap Auto Calibration. Since we need to do a lot of adjustment when we set up the RepRap Printer, the calibration part cost much time and hardly be accuracy. So we build the circuit and program the software to make it automatically, save time, free your hands.

Here is what we need to build this project:

• control board: MSP430 Launchpad (3.3v only)
• blue tooth-serial port : HC06
• touch sensor: TTP223B
