Overview
The Fly-E3-Pro is an STM32F407VGT6 based board.
There have been a number of changes in the way RRF builds for STM32F4, STM32H723 and STM32H743 boards are being produced from 3.5-RC4 and onwards.
The main changes are:-
- A build per board rather than all boards being contained in one build
- WiFi and SBC mode in one build. If there is an SD card present its in WiFi mode, if there isn’t one installed its in SBC mode. This matches the way the Duet3D boards operate.
- A board.txt setting to denote the WiFi module type installed.
Downloading the board firmware
Teamgloomy now generate per board firmware files. The correct file to use for this board is firmware_e3pro_f4.bin.
The latest firmware files can be found here
You can choose to download either the latest release or the latest pre-release if available. These instructions are applicable to releases from 3.5-RC4.
Once downloaded, rename it firmware.bin
WiFi firmware preparation
The latest firmware files can be found here
- WiFiModule_esp8266.bin
DWC (DuetWebControl)
The correct version of DWC should be downloaded from here.
The version you download should be of the same version number as the board firmware you downloaded above.
For example, if version 3.5.0 of the board firmware has been downloaded, 3.5.0 of DWC should be downloaded.
Generate a config
We provide a handy online tool to assist you in generating a set of config files for your 3D printer. The configurator doesn’t cover all options that RRF can be used for (such as dual motor axis control, which can be manually added later), however it does give a good start.
We also have a collection of user created configs which can be a useful reference. They can be found here
Manual board.txt Changes
If you are using a set of config files provided by someone else or have no need to use the configurator, you may need to create your board.txt file manually.
From 3.5-RC4, the majority of the board.txt configurables are pre-configured per board.
The preset configurables for the Fly-E3-Pro are listed below for reference.
board=e3pro_f4
board.longName="Fly E3 Pro STM32F4"

Unless you are overriding some of the above settings, or adding additional features, such as an accelerometer or 12864 display, a board.txt file is not required.
Sensorless Homing
Follow the instructions as found here
You can now continue getting the SD card in the correct format.
SD Card preparation
Now all the required files have been gathered, the SD card structure needs to be created.
SD Card Specification
When choosing an SD Card to use with RRF, we recommend one with the following features:
- a branded card with a speed rating of Class 4 or higher
- of up to 32GB capacity, formatted as below. RepRapFirmware does not support SD cards formatted in exFAT format.
Formatting
If you can’t use the recommended formatting tool, then the following points should be taken into account:
If you need to reformat the micro SDHC card:
- If the capacity of the card is 4GB or lower, use FAT16 format
- If the capacity is more than 4GB (up to 32GB) then you will have to use FAT32 format
- All cards should be formatted with 512 byte sectors
- For best upload speed choose the largest cluster size available, which is normally 64kb for FAT16 and 32kb for FAT32
SD Card Structure
The following structure should be replicated on your SD card.
sd card root/
├─ filaments/
├─ firmware/
│ ├─ WiFiModule_esp*.bin
├─ gcodes/
├─ macros/
├─ sys/
│ ├─ bed.g
│ ├─ board.txt $ If required
│ ├─ config.g
│ ├─ homeall.g
│ ├─ homex.g
│ ├─ homey.g
│ ├─ homez.g
│ ├─ pause.g
│ ├─ resume.g
│ ├─ sleep.g
│ ├─ stop.g
│ ├─ tfree0.g
│ ├─ tpost0.g
│ ├─ tpre0.g
├─ www/
│ ├─ contents of DuetWebControl-SD.zip
firmware.bin
In the above example, the contents of the sys folder have come from the online configurator. The WiFiModule file name will either be:
- WiFiModule_esp32.bin
- WiFiModule_esp8266.bin
- WiFiModule_esp32eth.bin
Final Setup
Once connected, power up the board using 12-24v and connect to the USB port on the board. Connect to the board using a program such as putty. Follow the instructions here to set it up for RRF. Change the Com port to match the Fly-E3-Pro and connect. The baudrate doesn’t matter.
Flashing the WiFi Firmware
Type in the following to putty
M552 S0
M997 S1
Wait for the uploading of the WiFi firmware to finish.
Sending your WiFi Credentials
Send the following
M552 S0
M587 S"your SSID" P"your password"
M552 S1
If you wanted to use “PassWord”, you would write P”P’a’s’sW’o’r’d” with the ‘ indicating the following letter should be lower case. Explanation here.
The blue light on the WiFi chip shoould then flash blue and will go solid when a connection has been established. The ip address will be shown on the serial connection. It is also possible to type just M552 to get the current ip address reported back.
The final thing to do is add the line “M552 S1” to your config file. This can be done through the web interface. This just ensures that the WiFi connection is started at start up. There is no need to add the M587 command as this is written permanently to the flash of the ESP8266 chip.
Once up and running
You will need to PID tune your tools and your bed. Please be aware that bed tuning may take up to an hour and tool tuning normally takes around 15 minutes. If it takes longer, that is also fine as up to 30 cycles may be ran.
To tune the bed, run the following command, changing the temperature (the S value) if a different tuning temperature is required.
M303 H0 S60
To tune each tool, run the following command, changing the temperature (the S value) if a different tuning temperature is required. This proceedure will activate the part cooling fans during the final phase of the tuning process so their effect is taken into account. If your printer has more than one tool, make sure each one of them is tuned.
M303 T0 S220
Once the tuning is complete, either copy the M307 command into the heater definitions or send M500, ensuring you have M501 at the end of your config.g.
If the tuning fails at the end, carry on saving the values as in most cases the outputted values still work correctly.
If the values still result in a heater fault, please refer to this wiki page for information about how to adjust the values manually.
