Ide 1.6.5 and module Due 1.6.4 :

This firmware is based on the popular repetier firmware and modified to work with first generation Da Vinci 1.0, 2.0 single fan, 2.0 dual fans and also AiO (NB:scanner function is not supported so AiO will work like an 1.0A)
If you change the board, currently DUE based are supported with RADDS, as well as Graphical screen and LCD with encoder, there are some sample configuration files provided for RADDS/DUE/GLCD using 1/128 step drivers.

YOU MIGHT DAMAGE YOUR PRINTER OR VOID YOUR WARRANTY, DO IT ON YOUR OWN RISK. When it is possible on 1.0/2.0, currently on 1.0A/2.0A and AiO there is no way to revert to stock fw so be sure of what you are doing.

###Support for 1.0A/2.0A/AiO(no scanner) is implemented and need feedback.

The board can be easily exposed by removing the back panel of the printer secured by two torx screws. Supported boards have a jumper labeled JP1, second generation boards have a jumper labeled J37. More info can be found on the Voltivo forum.

Here are just a few of the benifits of using this firmware:

• It works with host software such as repetier host and OctoPrint giving you full control of your hardware.
• It works stand alone if you use a WIFI SD Card.
• It allows the use of clear ABS (by disabling optical sensors), as well as other arbitrary filament brands/types as temperatures can be controlled freely and there is no requirement for chiped cartridges.

You can find more info on the Voltivo forum.

The current firmware is based on repetier Firmware 0.92 : bgm370 Da Vinci 1.0 FW

The previous version (based on repetier v0.91) can be found here

##Current Status ####Beta - so far so good

##Installation

1. With the machine off remove the back panel and short the jumper JP1 or J37 depending on model. Some Boards do not have jumper pins exposed but can still be shorted with a conductive wire.
2. Turn the machine on and wait a few seconds then turn it off again. The machine will have been flashed removing the current stock firmware and allowing it to be detected as a normal arduino DUE. NOTE: Windows users may need to install drivers to detect the board. Consult the Voltivo forums.
3. Use an arduino IDE supporting arduino DUE, version 1.5.8+ or 1.6.5, 1.6.0+ bring several issues, but 1.6.5 seems working well with Due 1.6.4 module for board manager.
4. Update arduino files (variants.cpp and USBcore.cpp) with the one(s) present in src\ArduinoDUE\AdditionalArduinoFiles\1.5.8. or in src\ArduinoDUE\AdditionalArduinoFiles\1.6.5 according your IDE version
   NOTE: You do not need to compile arduino from source these files are in the arduino directory structure. On Mac you will need to right click on the Arduino.app to Show Package Contents.
5. Open the project file named repetier.ino located in src\ArduinoDUE\Repetier directory in the arduino IDE.
6. Modify the DAVINCI define in Configuration.h file to match your targeted Da Vinci. See below.
7. Under the tools menu select the board type as Arduino DUE (Native USB Port) and the proper port you have connected to the printer. NOTE: You can usually find this out by looking at the tools -> port menu both before and after plugging in the printer to your computer's USB.
8. Press the usual arduino compile and upload button. If done correctly you will see the arduino sketch compile successfully and output in the log showing the upload status.
9. Once flash is done : restart printer
10. After printer restarted do not forget to send G-Code M502 then M500 from repetier's Print Panel tab or from the printer menu "Settings/Load Fail-Safe" and accept to save the new eeprom settings.
11. When update is complete you must calibrate your bed height!
    You can do so by homeing all axis, turning off the printer and manually adjusting the bed leveling screws until the glass bed is just under the nozzle at each end of the bed. While the printer is powered off you can move the print head by hand and slide a piece of paper over the glass bed and under the nozzle with a slight pull on the paper from the nozzle.
12. Next you can calibrate your filament as usual, and second extruder offset if you have.

For information on upgrading from or reverting to stock FW and other procedures please check Da Vinci Voltivo forum.

Do not forget to modify the configuration.h to match your targeted Da Vinci: 1.0, 2.0 SF or 2.0.
for basic installation just change :
'#define DAVINCI 1 // "1" For DAVINCI 1.0, "2" For DAVINCI 2.0 with 1 FAN, "3" For DAVINCI 2.0 with 2 FANS, 4 For AiO （no scanner)'
0 for not Davinci board (like DUE/RADDS)
1 for DaVinci 1.0 (1Fan, 1 Extruder)
2 for DaVinci 2.0 SF (1Fan, 2 Extruders)
3 for DaVinci 2.0 (2Fans, 2 Extruders)
4 for DaVinci AiO (no scanner)

Support for 1.0A and 2.0A: need to change #define MODEL 0 to #define MODEL 1

To repurpose the main Extruder cooling fan to be controlled VIA G-Code instructions M106/M107:
Set REPURPOSE_FAN_TO_COOL_EXTRUSIONS to 1, do not forget to add a fan with power source to cool extruder permanently if you use this option.

FAQ

##Implemented

• Standard GCODE commands
• Single/Dual extruders support (DaVinci 1.0(a)/2.0(a) and AiO without scanner)
• Single Fan / Dual fans support according printer configuration
• Repurpose of second fan usage to be controlled by M106/M107 commands on Da Vinci 2.0
• Sound and Lights management, including powersaving function (light can be managed remotely by GCODE)
• Cleaning Nozzle(s) by menu and by GCODE for 1.0, 2.0 and AiO

• Loading FailSafe settings
• Emergency stop (Left key/Down key/Ok key in same time)
• Increase extruder temperature range to 270C and bed to 130C
• Add temperature control on extruder to avoid movement if too cold
• Add fast switch (1/10/100mm) for manual position/extrusion
• Command for bed down
• Several fixes from original FW
• Watchdog
• Basic Wifi support for module ESP8266 (https://github.com/luc-github/ESP8266/blob/master/README.md#result-of-esp12e-on-davinci)
• Customized thermistor tables for bed and extruder(s) as Davinci board do not follow design of others 3D printer boards so standard tables do not work properly check here
• More to come ....

##How to test Watchdog ?

• Connect repetier host and send M281 command.
  This will generate a timeout after showing "Triggering watchdog. If activated, the printer will reset." in serial terminal.
  If watchdog is enabled properly and working the printer will reset and restart.
  If not, you should have "Watchdog feature was not compiled into this version!" in serial terminal and printer will not automaticaly restart.
