Mellow FLY-CDY-V2 motherboard

recently (3-2021) I have been setting up my new 3d printerboard from Mellow, an STM32 board that is named FLY CDY V2. It is fully compatible with Duet2Wifi and also uses its wifi-based 3d printer management system.

The config file I made for this setup is HERE

The FLY_CDY_V2 board comes completely empty so I added the firmware.bin in the /sys directory, after I had an empty SD card filled with the clean reprap directories and -files.

Next to the firmware.bin. also a board.txt is required to be available in /sys with some settings, with the following content:

//Config for fly-CDY
board = fly_cdyv2
led.neopixelPin = D.15;
//wifi pins
8266wifi.espDataReadyPin = E.10;
8266wifi.TfrReadyPin = E.12;
8266wifi.espResetPin = E.11;
8266wifi.serialRxTxPins = { D.9, D.8 };
heat.tempSensePins = { B.1 , A.3 , C.4 , D.14}; be aware that D.14 is not a temp pin but a heat pin, is this wrong??
stepper.numSmartDrivers = 6;
serial.aux.rxTxPins = {A.10, A.9};

This board.txt is already OK for 2209 drivers and for the use of the neopixels output.

In the pdf that is provided by Mellow on the Github page for the reprap STM32 boards, section FLY-CDYV2, everything is explained as to get wifi up and running,  configure config.g et cetera.  

In my config.g everything needed to work properly is already done, as is with my board.txt.

I made the config for a Cartesian printer with single X,Y,Z steppers and a triple hotend with 3 extruders, 1 heater and 3 nozzles.
Included is: Neopixels, BLTouch, 3 filament sensors on the X,Y- and Zmax inputs, active fans for hotend tool on fan1 and object on fan0
If so desired, sensorless homing is possible with the correct driver boards. In this version, 3 optical endstops have been used on inputs xmin, ymin and zmin.
Retraction is set OFF in this firmware by default, but may be swiched ON to make the triple hotend drip less (2 mm retract and -0.5 extrude without Z-hop), do experiment with these settings!
Please be aware that some pin names for the FLYCDYV2 board differ form the Duet’s naming convention like “bed” versus “bed-heater” et cetera.
Plus, some typical Duet2wifi extensions are NOT available like the GPIO bus.
The FLYCDYV2 has some interesting standard extra’s like the BLTouch connector with power, driver pins and Z probe pins, the Neopixel connector AND the 6 driver slots and 3 extruder heaters/sensors/fans!
It is quite simple to change this setup to a dual Z axis with independant Z-motors and either single extruder or a dual setup, single or dual nozzle, mixing or non-mixing.
