Build using Creality Melzi Board and Display

Just finished a DIY build using a Creality 1.1.4 board and the display

//Creality E0
#define extEnable 14
#define extStep 1
#define extDir 0

//Creality Z-axis
#define selEnable 26
#define selStep 3
#define selDir 2

//Creality Y-stop
#define trigger 19

The display is more complicated.. using u8glib and the commands are quite different. Haven't made all of this switchable by #define

void oledclear(){ 
#ifdef Creality
  oled.firstPage(); 
  do { 
  } while( oled.nextPage() ); 
#else
  oled.clear();
#endif
}

void displayText(int offset, String str)
{
    oled.firstPage();
    do {
      oled.drawStr(0,22,str.c_str());
    } while (oled.nextPage());
}

Setup:

#ifdef Creality
  oled.setFont(u8g_font_6x10);
  oled.firstPage();
  do {
  	oled.drawStr(0,22,"3DChameleon Mk4"); //print a welcome message
  } while (oled.nextPage());
#else
  // enable OLED display
  oled.begin(&Adafruit128x64, OLED_I2C_ADDRESS);
//... rest of normal display setup
  displayText(0, "       Ready!");
#endif

libs:

//#define Creality  //enable for Melzi board

#ifdef Creality
  #include <U8glib.h>
#endif
#include <SSD1306Ascii.h> //i2C OLED
#include <SSD1306AsciiWire.h> //i2C OLED


#ifdef Creality
 U8GLIB_ST7920_128X64_1X oled(30, 17, 28); // Creality Melzi with single ribbon cable
#else
// Declaration for an SSD1306 display connected to I2C (SDA, SCL pins)
  #define OLED_RESET  -1 // Reset pin # (or -1 if sharing Arduino reset pin)
  #define OLED_I2C_ADDRESS 0x3C
  SSD1306AsciiWire oled;
#endif

Hey here,

Super interested in this as I have an old cr-10 board I can use. Any chance of a walkthrough to getting this setup. Or rough step by step to get here. Any help appreciated. Am I flashing the mk4 firmware onto the board?

Hello, I was able to get the 1.1.4 board working and also the OLED screen, now I have to configure the slicer

Hi, i am interested in using my old melzi board for a 3d chameleon build, but I would not be using the screen. Would I just use the first block of code, or is there a way you could send me detailed instructions on how to get the board working and which pins to use.

You can use the code as is... the screen doesn't have to be present for the code to work.

Awesome. One more question does this code get added into the original firmware code using arduino ide?

Hello, I am interested in your project and I have the same board but the extruder driver is burned. I have the X, Y and Z motors working. My idea is to use the other motors that are working by reassigning the pins. Can you share the complete file so I can burn it on the 1.1.4 board? I would appreciate your collaboration.

I tried to use my 1.1.4 board but i can't get to do nothing.

Does it have a bootloader? If not, look how to flash one. You will need an arduino uno.

Now that the chameleon is open source, this is a cheap easy to make one for anyone interested. Just pick up a cheap ender 3 (you can find them from 20-80 USD depending on where you look) and then you will have the motors, mainboard, t-nuts, screen, and some other parts to make a DIY chameleon. It's even better if you just have an old ender 3/cr-10 lying around that can be used to make a chameleon.
