RepRap Auto Calibration
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

Bill of Materials[edit | edit source]
- control board: MSP430 Launchpad (3.3v only) -$14.01
- blue tooth-serial port : HC06 -$9.99
- touch sensor: TTP223B -$5.99
Instruction[edit | edit source]
Combine the circuit following the figures below
- Combine the control board and the blue tooth-serial port board
- blue tooth-serial port board VCC to control board J6 VCC
- blue tooth-serial port board GND to control board GND
- blue tooth-serial port board TXD to control board P1.1<UART>
- blue tooth-serial port board RXD to control board P1.2<UART>
