Easy setup

[MilanGajicBuva]

Hi Luc, I love the idea of this project.

Reason: I can not get it to compile (D1 Mini Pro) and I do not understand the errors or the solutions provided when it comes to devtools, libraries etc. I've spent two days and got nowhere. Timewise it would have bean cheaper to get an RPi with Octoprint.

Idea: Would it be an idea to make it more accesible to people with basic technical skills?
I was thinking along the lines of a tool to burn a basic ota bootloader on the ESP, and then have a configuration tool that generates and compiles an ota file you can send to the device.
I realise this might sound like lazyness, but I know a bunch of people who do cool things with 3d printers, but would probably struggle with just installing the ArduinoIDE. This would make it accesible to them and possibly save a bunch of old printers from the dump.

Thank you for the consideration.

Best regards and keep up the good work.
Milan

the easiest setup is vs code with platformio, no need to install anything else everything is preset

Thank you for the fast response Luc. That is the one I was trying today, seemed to be going well> Downloaded the project from github. Ran the configuration tool. Downloaded platformio.ini to root of project. Installed VSCode. Loaded the folder and let VSCode install all the things. But then when I try to compile I get one error after the other. It might be obvious to someone like you, but to me .. it is not. *** missing SConscript file 'platformIO\\extra_script.py' esp3d\notifications_service.cpp:38:10: fatal error: WiFiClientSecureAxTLS.h: No such file or directory Op za 27 sep 2025 om 14:00 schreef Luc ***@***.***>:

you need all the repository not only the sources files

[luc-github]

also what version are you using ?

WiFiClientSecureAxTLS.h is no more used in 3.0

configurator is for 3.0 only

[MilanGajicBuva]

Hi Luc, With your help, I managed to get 2.1.x on the D1 Mini Pro and connected it to the 4.2.7 Ender 3 board. Got 3.3v power and ground from the filament runout sensor conector (used a hacked z endstop cable). I soldered the serial connection to the pins 2&3 on the CH340G chip: 2 TX -> RX on the D1 3 RX -> TX on the D1 I checked connections and they are good; also checked for shorts and there are none. Both the Ender and ESP3d are set to 115200baud. The D1 powers up anr ESP3D is running , but there seems to be no serial comunication, to or from the printer. The Serial blinky led on the 4.2.7 is not blinkinh either. Serial on the printer works fine via USB (Pronterface). Do i need to set the correct board somwhere, maybe it is usineg wrong pins for serial? Or manually set the serial pins? I managed to get data on the oscilloscope and while measuring i touched something and briefly got an ip address and the printers made some movements and sound. But now im not measuring anything anymore on the TX:( [image: image.png] Here's the pictures of the progress: https://photos.app.goo.gl/4LkdYTFkrxvj5YCd8 Op za 27 sep 2025 om 17:31 schreef Luc ***@***.***>:

if no com it means wiring is incorrect
the minimum wiring is rx/tx/gnd if power supply is external
I do not know this board but you may review your soldering point to be sure they are usable rx/tx
