Pangu i3 .. the best price / quality ratio ? (Page 3 of 3)

nothing for the moment :0 .. I refine my printer calibration

I have my pangu for only one month and it works satisfactorily for only 2 weeks.

the Extruder calibration is VERY important and i have little problem with my current filament.

il will try to print one of your screw this week-end if i have time

all the change that you can make in the slicer depending of your filament (retractation, speed,  bridging, temperature... )... now it's a "try and see" game...

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).

Here are some of my prints on the Pangu, as follows:
Attachment 1 is my second print, failed because of repetier crash
Attachment 2 is a Beach Girl figurine, its just a couple of cm high
Attachment 3 is a planetary gear. 2nd try printing the model, scaled up about 15% because i didnt had appropriate tool size to rotate the gears
Attachment 4 is one of my last prints, architectural detail
Attachment 5 is a set of Geared Heart. Some of the pieces laminated with time, even though I vapored all of them

they improved the packaging since mine .. the case-box is a good idea instead of of lot of small bags..

do you calibrate the step/mm for the extruder ? (what is your native language ?)

first, do you use the sprinter firmware (original) in your i3 or my modified marlin firmware ?

if you use the marlin, you can follow this :

and this update : http://solidoodletips.wordpress.com/201 … on-update/

it's for a solidoodle but the method is the same for any printer with marlin firmware..

i don't know if you can change the step/mm value in the last version of the sprinter firmware thru repetier, or you need to change the value inside the firmware then flash the modified firmware. you can try to follow the update method
