[solved] FLY E3 V3 PRO Bootlooping? | Reprapfirmware, DSF and DWC | Page 1

Hi, my friends and I are working on a print farm. While setting up our second printer, we encountered some issues.

For the first board, I set up the file structure, which included the DWC components in the WWW directory and the firmware.bin file in the root directory. This setup worked flawlessly on the first attempt without any issues.

However, when setting up the second board, I had my friend replicate the process, and I double-checked his work to ensure that all the necessary files were present. After inserting the SD card and powering on, the board recognizes the firmware.bin file, proceeds to install and then delete it. But, I suspect it's entering a boot loop afterwards. The two LEDs near the fan controllers start blinking every 20 seconds, coinciding with my USB terminal disconnecting. YAT does receive responses, indicating that RRF is installed. However, there's no activity from the WIFI module, and for some reason, the runonce.g file isn't being executed and deleted as it should be.

We're currently running version 3.5.0 RC.3.

Can you zip the contents of the SD card and post them here please. Don't edit any of the files or even open any

#

Then, once you have zipped the files, edit the board.txt file and remove every line except the board = line. Try booting it and it should be stable

#

Then add the lines back detailed here under manual editing board.txt https://teamgloomy.github.io/fly_e3_pro_v3_connected_wifi.html

Thanks for the epic support @hallow terrace

#

Tried to boot again after adding back the board.txt config but I'm not seeing anything printer related on zenmap.

hallow terrace Feb 28, 2024, 8:38 PM

#

did it boot with the single board.txt line?

peak gazelle Feb 28, 2024, 8:39 PM

#

booted but no wifi connection

#

I think

hallow terrace Feb 28, 2024, 8:39 PM

#

yea, thats expected as it doesn't have any of the wifi lines in and you won't have flashed the module yet

swift marten Feb 28, 2024, 8:42 PM

#

@peak gazelle use USBC cable and YAT to dump the current status useing M122

#

just to see if alive

peak gazelle Feb 28, 2024, 8:53 PM

#

Reprap is active after sending that command thru serial, the connection is stable

hallow terrace Feb 28, 2024, 8:54 PM

#

great. now put this stuff pack in your board.txt and continue ```board = fly_e3_prov3
//WiFi pins
8266wifi.espDataReadyPin = PE_13
8266wifi.TfrReadyPin = PE_14
8266wifi.espResetPin = PE_15

//ESP32 RX/TX Settings
8266wifi.serialRxTxPins = { PD_9, PD_8 }
heat.tempSensePins = { PA_3, PA_4, PA_1 }
stepper.numSmartDrivers = 5```

swift marten Feb 28, 2024, 9:17 PM

#

Okay... this is WEIRD. M587 followed by the credentials causes the board to crash and terminal disconnect.

#

behavior of the ESP is buggy in general...

hallow terrace Feb 28, 2024, 9:17 PM

#

Have you flashed the WiFi module?

swift marten Feb 28, 2024, 9:17 PM

#

yes but we will retry

hallow terrace Feb 28, 2024, 9:18 PM

#

Did you flash the correct WiFi firmware?

swift marten Feb 28, 2024, 9:20 PM

#

now it is getting stuck trying to connect when we run M997 S1

#

instalation failed due to comm write error

hallow terrace Feb 28, 2024, 9:21 PM

#

Send M552 S0 and then M997 S1

swift marten Feb 28, 2024, 9:21 PM

#

yup we did just that

#

Could be a hardware problem. I should check if anyone knocked any resistors off or something dumb while installing it. next time I'm there

hallow terrace Feb 28, 2024, 9:24 PM

Post the output of M122 P200

You'll have to change the YAT settings so get the full output

It appears to be detected correctly and has the right pins set

#

Can you post the full output of you send M997 S1? How are you powering the board?

peak gazelle Feb 28, 2024, 9:36 PM

#

24v power supply, came with the ender its being used on

GG @peak gazelle, you just advanced to level 1!

swift marten Feb 28, 2024, 9:38 PM

#

Power inputs for heater are 16 AWG with a thinner wire daisy chained to the MCU power input.

swift marten Feb 28, 2024, 10:08 PM

#

I'll take a look at it to make sure ther are no damaged traces etc and get back to this later

#

Checked the front and back for damage or bad solder, checked connections. Put this on the SD card and powered it up.

#

The bottom two LEDs turn off for a second every 20-30 seconds

swift marten Mar 1, 2024, 3:08 AM

#

Still unable to flash wifi firmware through M997 S1 but I am able to disable it through M552 S0

#

#

This looks like it might be a problem…

swift marten Mar 1, 2024, 3:44 AM

#

#

We will try this

#

Didn't fix it. Ill reflow the other sides just in case

swift marten Mar 1, 2024, 4:30 AM

#

@hallow terrace got it working!! There was also a resistor next to it that was possibly soldered badly.

swift marten Mar 1, 2024, 7:43 AM

#

Might want to forward this to mellow. Seems like the ESP32 was not flat against the main board
