Hi everyone I am new to the forum and to 3D printing.
All thanks to all the opensource information and ysb. I got myself a pangu i3 (0.4mm 1.75). I would say I am quite satisfied with the result after some careful calibration and trail & error.
cookiemonster,
How is your LCD, encoder & buzzer project?
I manage to get my working with and 2004 i2c LCD + encoder (did not add an buzzer to it) using ysb's firmware.
For those who is interested here is what I did :-
EXT connector
D17(SDA) - LCD_SDA
D16(SCL) - LCD_SCL
D11(TX1) - ENC_A
D10(RX1) - ENC_B
VCC_5V - LCD/ENC
A2 - ENC_SW
GND - LCD/ENC
configuration.h
------------------------------------
#define RA_CONTROL_PANEL // enable if using PCA8574 I2C
-------------------------------------
#if defined(RA_CONTROL_PANEL)
#define ULTIPANEL
#define NEWPANEL
#define LCD_I2C_TYPE_PCA8574 // I2C I am using
#define LCD_I2C_ADDRESS 0x27 // I2C Address of the port expander some is 0x20
#endif
------------------------------------------------------------------------------------------
#define NEWPANEL //enable this to auto enable encoder in pin.h (under #ifdef ULTIPANEL)
-------------------------------------------------------------------------------------------
pin.h
---------
//The encoder and click button
#define BTN_EN1 11 // no change if connects to D11(TX1)
#define BTN_EN2 10 // no change if connects to D10(RX1)
-------------------------------------------------------------------------
#define BTN_ENC 29 // Change from 16 (ori) to 29 = A2 (ext connector), before Panelolu2 endif
------------------------------------------------------------------------------------------------------------------------
IMPORTANT NOTE: Do not use the standard I2C library, download the library from the configuration.h information link
That's it. You should be able to control and print from the on board uSD card using the LCD and encoder without an PC (Yeah).
Thanks to DIYcrap (diycrap.blogspot.de/2013/08/i2c-display-and-rotary-encoder-on-melzi.html) Where I got started and reference to but due to differences in firmware steps defer(Lots of trail & error and was about to give up but decided to force myself to study the firmware line by line and finally got it working).
