FYSETC Board - The E4 board is a minimal 3D printer control board based on the ESP32 microcontroller from ESPRESSIF, with built-in Wi-Fi and Bluetooth.
Home Page: https://www.aliexpress.com/item/1005001703930983.html
I've experienced some issues which I think are related to web access. I've not looked how the websockets have been implemented but I trust the people who wrote the code are better programmer than me.
It appears to happen when my PC goes to sleep (iMac) with safari open on the ESP3D page.
I make a point of closing the browser tab every time as a work around, and I've only seen it once leave a blob in a 12 hour print.
I replaced a random layer shifting board in a Ender 3 V2 with this one and I am very pleased with the results. The vertical walls are so much cleaner/smoother.
Also the machine uses less power now, the PSU fan turns off during a print and the hottest stepper motor is now 38 degC, I couldn't touch them on the stock setup.
Hi,
Im trying to upload a sketch from Arduino IDE and i get following error:
A fatal error occurred: Failed to connect to ESP32: Wrong boot mode detected (0x13)! The chip needs to be in download mode.
Is there a possibility to put the board in download mode?
Thank you on advance

I have just started using the E4 and I am impressed with the simple KISS approach. It just works. But I have two feature request for a E4 V1.1 board. The first is a Bed level sensor. I would like to uses this with a delta printer. The second request is for a interface to one of the cheap OLED displays for ESP that can show hot end temp, bed temp and print progress. The URL works but would be nice to have a OLED on the printer so when I look at it I can see where the print is at.
I failed to build the firmware downloaded from here after i upgrad PlatformIO to the latest version (Core 6.1.3).
It seems that the build-in library of ESP32 cannot be read correctly.
Please help...

MARLIN_ESP sees the access point, but does not accept the default password. how to solve the problem?
Recently bought a new FYSETC E4 board, plugging it in doesn't create any wifi so I can update the firmware. Also I don't know how you can put the ESP32 in download mode to upload a new firmware. How can a new firmware be uploaded?
Thanks.
The bottom silkscreen is different from the top silkscreen for all the stepper connector
I can't connect to webui when I switch to STA mode..
i used to have a FW that could do it (2.0.9.3)...but i deleted it because i forgot to enable eeprom_setting ,and now I can't do it again
firmware_K.zip
after update firmware via web pages. I cant reach to E4
it seems on PC when USB connect on COM3
but do nothing
there is no any wifi connection
Hi, Im trying to configure the board and change the driver current, but i tried setting monitor driver status, but i get this message:
18:58:52.344 : E (5870) uart: uart_get_buffered_data_len(1342): uart driver error
what can be causing this.
I have already knowledge of marlin and esp3d.
thanks.
How can I connect all the pins to a bltouch?
I can solder/cut trace etc just don't know which pin to use and config
Edit: i removed the opto isolator and bridge the pin, the input filter capacitor 100nf
-z-min for bltouch power/servo pin (+5v SERVO GND)
-y-min for bltouch signal trigger plug
-made all home switch to normally open and combine all 3 limit switch pin to x-min
Only down side is you need to make sure all axis are away from homing switch before sending G28 homing
You will still be able to have your heated bed :)
#define X_STOP_PIN 34//34
#define Y_STOP_PIN 34//35
#define Z_STOP_PIN 34//15
#define Z_MIN_PROBE_PIN 35
#define SERVO0_PIN 15
cant compile with new platformio

I want to reprogram for my private purpose! Please give me schematic , Thank you
Need help custom config marlin. Vs code platform io.
Librays dont install
Bugfix doesnt have e4 board.
Where do i get a working version i can edit please
Looks like it is supposed to have already been addresses in "Update platformio.ini to fix class WiFiClientSecure compilation error" {4b36034}, but for me it's still failing. Can't build the firmware!

Hi,
Ist planed to support Klipper Firmware with the E4 board and ESP32 chip.
Is somebody working on that?
Also is it planned to have web interface Mainsail run on the board as well without using an Raspberry pi.
Greetings Ixman
The PDF schematic in this repo specifies the drivers' current sense resistors as 0.22R. However, the actual board I received has 0.11R resistors, which are the typical value used for these drivers.
Hello.
I can not figure out how to connect to the board anymore: I have successfully complied and flashed Marlin 2.0.9.1 for the E4 board (using ESP web interface, as I was able to connect the board to home wifi network). After that E4 disappears from my wifi network, but it successfully works with USB connection and repetier host - it communicates just well.
Could you please share how to got wi-fi working back? There is no marlin esp device in wi-fi network as well.
I'm using the TB pin for using a endstop for filament runout. The filament sensor runs perfectly but the TE pin don't read the extrusor temperature when I plug the endstop in TB. Can't I use this pin for a filament runout sensor? Otherwise, is there any other pin on the board that I can use?
//#define TEMP_BED_PIN 39 // Analog Input
#define FIL_RUNOUT_PIN 39 // RUNNOUT FILAMENT PIN
Thanks.
Hello everyone, can someone explain how to synchronize the Y and E axes in hardware and make an XYYZ machine on the E4? Thanks in advance.
I want to use a servo instead of the Z-Axis Stepper motor. The servo would be PWM controlled which is something the ESP32 firmware can support on every GPIO pin.
Is there any GPIO pin from the ESP32 accessible on the board that can be used for this?
Anyone know? please help me, thank you so much!
The provided E4 is for a cartesian printer. Is there a chance of a working example for a Delta type of printer? I have a Tevo Little Monster that I am trying to use the E4 with. I keep having issues with the build failing. Something to do with the Pins.
I will continue to try and resolve the build error, but any input would be much appreciated.

Hello, I recently received one of these boards but I'm having trouble using the SD card on it. It does not seem to be detecting an SD card present in the slot. Has anyone else dealt with this error?
Can I get the Pin numbers for RXD0 and TXD0
Are they allocated to anything?
Thanks
In the process of compiling the Marlin firmware with CoreXY support, I flashed the board via its web interface. Strangely, the board now connects to the WiFi network that I had configured before I flashed the board. Unfortunately, the IP address of the board does not expose any service that I can connect to - it seems to be bricked.
Is there a way to flash this board via USB in order to unbrick it?
I installed the firmware found here on my ender 3 but the fan is always on.
Sending the M106 S0 command or the M107 command gives me a message:
Ok
ok
but the fan remains on as well as the LED on the board.
E4 is showing T0 as a target to both hotend AND bed temperature. Is there any way so the system returns te Hotend AND te bed temperature, not only hotend?
