Add Wifi To A 3D Printer - SKR 1.4 - ESP8266 - ESP3D - Chris's Basement

Apparently you can connect these cheap WIFI boards up to the TFT connector that is available on pretty much all of the Bigtreetech boards (most don't have a WIFI connector). Anychance you could make a video on that? Thanks.

hello, in my case there is no option to upload file system image

is there away to change the ip address. i have a conflict with my router it is the same login ip address

Fun Fact: if you swap VCC and GND, the power light will still light up, but it will refuse to program.

Also, it's a lot easier to program on one of the programming jigs, that has the 8 pin socket on it. I forgot I had one, and tried with a FTDI first. Then I messed around trying to figure out why it wouldn't program, until I just tried another module. :)

I would need to know how to connect esp8266 to STM32 from geetech. There is a straight 8-pin input and there is no indication of what these pins are.

I dont have env:esp8266 when I goto platformio build

I cant upload anything via webui even has a short name

I've already seen that people have operated the ESP modules with 5 volts. The manufacturer does not specify how long it takes for these to burn out. Maybe hours, days or years?

But the manufacturer states that less than 4 volts should be allowed. A Lipo-FE cell with 3.6 volts is possible without any problems. A normal LIPO with up to 4.2 volts is your risk with a ESP.

RX and TX each need 1k in series to the 5V system. That should already be on the board. Voltage dividers degrade the digital signal because fast 1s and 0s have to be transmitted.

All data communication is handled via TTL serial. The display, the ESP8266 and the USB port is nothing more than a modern serial port.
If the ESP module can be plugged in at the display, the firmware on the printer board probably does not need to be changed.

Great videos Chris. Like this one, there are always great tips to point me in the right direction. I just did a mod on my old Kossel Linear, extending the frame width, adding the SKR 1.4v Turbo, and the ESP3D wifi mod. The ESP 0s1 had me stumped, after doing the firmware. I'm using Marlin 2.1.1 and 2.1.2 of the ESP3D, with Sensorless Homing.

I'd done the Flash tool method, but I could never get the setup window. the same happened with the vscode compile. But I realized that when asked to upload, you have to upload the ...index.html.gz, the 404.htm, and the faviicon.ico.... files. If all 3 aren't uploaded, the setup window never loads. Also, looks like the latest Marlin has the serial code updated to except the wifi via port 3. I defintely prefer compiling, since I can get updates without waiting.

not work on marlin 2.1.1

i just wanna say. I had tried getting my Wifi module to work properly and failed until used the methods provided in this video. i was able to get it up and running no issues at all.

This didn't work for me does anyone know how to install firmware?

I don't have "Upload file System Image" in my VS Code. Your video is old and useless.

Hi Chris, Great video, thanks! I got a problem, I did everything you did more than 5 times but the esp8266 can't connect with the printer on the esp3d website, I also changed the serial port but nothing different happened, I'm trying to solve this problem for days, could you please help me with that?

I'm going to try this with my Neptune 2. esp32 dev board already has Usb for upload. Jump some wires and it should work.

Is there a way to add ethernet to octopus board instead of wi-fi? Probably a ethernet breakout board with UART or SPI interface. Looking to connect my RPi remote server to 3d printer.

Hey i hope someone can help me here. Im trying ot get at SKR V2 with an ESP32 to work. i flashed the ESP32 got the WebUI running and got the serial sorted to a point at wich i can read consol output from marlin in the WebUI but for somereason that only works one way... not the other. So, when restarting the Printer it reads the "sdcard ok" and version massages but when i type in M115 nothnig happens ia there a setting in Marlin where i need to tell it to listen spezificly to Serial_3 ? or should it just take Serial comands from any port ?

what's best, if you replace the 23S80 flash on the ESP01S by a 25Q32 you have enough space on the filesystem. Requires some soldering skills 4 sure, perhaps simply adding a mini D1 ESP 8266 board would have worked aswell ... but I was unsure about that.

i have everythign working apart from it connecting to the printer the baudrate is set but still does not connect to the printer

THE UPLOAD FILE SYSTEM IMAGE IS NOT THERE IN MY VERSION OF vscdode

right chris iv come back to this one as i want to add wifi iv come across a problem i have wired everything as is comiled with vscode but when i try to upload all iyt keeps saying is Connecting........____....._____....._____....._____....._____....._____.....____

I need help. I just received a couple ESP01 modules and programmers from Amazon. The programmer does not show up as a COM port as expected, and, thus, the flash tool will not function. It says USB2.0-Ser! in "Other Devices" under Device Manager with Windows 10, with a yellow triangle. I tried to update the driver, and find a driver...no luck.
Any ideas?

Hi Chris! More than a year has passed already, still this video renders tremendously helpful. Thank you very much for the excellent content you produce and share.

I just used this video to help me setup my new BTT E3 RRF board with built in ESP3D. I created firmware via your instructions, but needed to place it on an SD card and renamed it "ESP3D.bin" per BTT instructions. (The WiFi chip is soldered to the motherboard and cannot be removed to use a USB flashing tool.) I power cycled with the SD card in to load the firmware. Then I was able to connect to the ESP3D access point via your instructions. It told me the "index.html.gz" file was missing and to upload it. It had a screen in which to do this (I used the top option) and it allowed me to upload all three files (I did them one at a time.) Once uploaded, I restarted the printer and then was able to continue with the printer setup. Thank you again for this information, and for also explaining the serial ports options in Marlin. I has emailed BTT and they said I had to use serial port=3 in Marlin for WiFi, but then I lost my BTT TFT screen in touch mode--no printer connected (Marlin mode always works). Your information went over the different serial ports, their options, and what they connect to. I have a BTT E3 RRF motherboard and a BTT-TFT35-E3-V3.0 touch screen on my CR-10S. It is my understanding that I will not be able to have all three items (TFT screen in Touch Screen mode, USB port on motherboard, and ESP3D WiFi module) all working at the same time because of Marlin only currently supporting 2 serial ports. P.S. I did not see the same warning that you did, and when I tried to add the "board_build.ldscript" option, my builds would fail. I put it back to the default, and it built fine.

Hello Mr's Chris, I wont to ask something. Why I don't have "Upload file system image" - option in VS Code, when I try compile ESP3D according to your guide?

In the recent version of Marlin PIO folders it looks like there's some else/if logic that requires you to assign the pin using a variable or something instead of directly editing the pin3 definitions here.

It would be great if you could do a video for The Wi-Fi install on a Prusa mk3s

Hello Chris. I have a question. Can i flash my board (skr 1.4), with the btt writer and wifi module, without sd card inserted on the main board ? ( SKR 1.4 refuse flashing the firmware through the sd card . I have tried almost everything and that thing does not want to corporate. I am just one step before i buy a new board.) Or perhaps i could flashing the main board firmware with writer-wifi setup through the btt tft lcd sd card slot(TFT 35 V3 ) ? Thank you

hello, i have problems with the esp8266 module, i do configure everythin just fine, and when i connect the module to the usb/serial adapter the esp3d ssid is ok, but when i do connect the module direct to the skr 1.4 board the module do not work, i tested the pin of the skr that goes to the ch_pd pin from and the output is 0V, that must be 3.3v, any help for this??

what is the difference between esp01 and esp01-s?

Chris, thank you for these excellent instructions. I loaded the latest code, but when it came time to 'load file system image' I could not see as an option. Clean has replaced "Erase Flash'. Any ideas? thanks again.

have u got any videos of how to setup dual z endstops please as im struggeling with it

i have no 'upload file system image' feature but everything else works. Idk whats wrong

your could do with slowing down sounds like your on speed

I don't know if you can run octoprint with this? Or do you need an arduino to use octoprint?

whats the wifi password for it

hi chris i am having problems after i enable wifi support i get file not found

Chris could you make a video on flashing firmware to an skr1.4 either via octoprint or one of these esp modules?

Hi Chris, I love that printer. Have you talked about it in any of your videos?. I've seeked in your videos with no luck. Thanks.

In order to get the index.html.gz file to upload, I found that I have to download only the language(s) you want from the "Languages" folder. I'm not sure how many languages can be stored, I only tried English. The one on the default page contains ALL the languages they support, and file won't fit on many ESP8266 or ESP32 variants.

Hope this helps someone!

Hi, Chris, I rly love a bunch of your videos including the one we have here.
As I was giving that process a try, I noticed that video is actually outdated, as the framework changed drastically in that section (they actually fixed that issue).
It is actually easier now but quite different.
hope I helped bringing it to your attention!

God youre a h ero

Thx, now it works! Nice work!

do u need the DCDC converter? SKR1.4turbo and esp8266
