Fly-E3-Pro-V3 Mainboard
- Buy the board: Fly-E3-Pro-V3
- After you get the board, follow the steps for Fly-E3-Pro-v3 General Information
- Also see Firmware - Report Settings
- Follow the steps for Fly-E3-Pro-V3 installing RepRapFirmware with the Configurator or try this Firmware pack.zip.
Commands:
M122 - To Troubleshoot
Errors:
- Error reading from serial device.
Also:
I got to the point where the firmware was flashed and I was trying to type in my wifi credentials but it wasn't taking it. I decided to try starting over with new firmware files on the SD card but the usb cable might have been loose when I tried.
Now when I connect the Fly-E3-Pro-V3 to my computer via USB it shows up in device manager for 20 second and then I hear windows ping letting me know it disconnected, and then it immediately reconnects. Then it will keep disconnecting and reconnecting every 20seconds. I'm thinking the firmware on the board might be corrupt now but it wont let me reflash to start over.

You flashed the ESP8266 image and not the ESP32 one

I dropped the contents of sys into the SD card and got
I redownloaded files from the configurator but made sure ESP32 box was checked
then I got
I tried putty again and it worked, I'm assuming I opened putty too fast, before the board USB was fully plugged in
Still getting
I removed line brake from SD root > sys > board.txt
Still: Error: Installation failed due to comm write error
The Module isn't idle any more
I redid the spacing in the board.txt and it might be working
Nope
But then I ignored it and when to the web bowser
Power needs to go to both +

Jay on discord:
Have you sent your wifi details using M587?
Does your network support 2.4ghz? The esp32 doesn't work with 5ghz networks
M587 returns: Failed to retrieve network list: SPI timeout

Remembered networks:
SBG8300-5685 IP=0.0.0.0 GW=0.0.0.0 NM=0.0.0.0
M588 S"*" < Deletes saved network information
I changed my network name and forget, I entered the correct name and it's working now.
At Jack's house I tried to connect to new WiFi
I did:
M552 S0
M588 S"*"
M587 S"SSID" P"password"
M552 S1
(M587 can be used as a check sum to see what wifi is currently on the board)
