Add wifi to your Bigtreetech mainboard/touchscreen - ESP-01S guide

[@LesFishingMoreCatching]

I just added this to my Biqu B1 with the TFT35 B1 v3.0.1. I ran into two issues, as mentioned in another comment below while selecting the firmware file for the esp, you need to check off the box left of the file name and type the 0x00000 address into the box on the right. Also I had to edit a config.ini file and enable the 115200 baud rate on the 2nd communication device. Also you can can configure the ESP with the flash tool by just providing power to it after the flash.

[@DinkaFox1]

Just wanted to give a big thanks to you for this comment. I was following the instructions in the vid but it did not seem like the firmware was flashing. I assumed it was an issue with the ESP module I bought but new ones I got didn't work either. I noticed in the guide, the textbox was highlighted green but I didn't see the checkbox marked, so I assumed it might not need it. This was my issue all along. I was able to finally properly flash the firmware following the step you provided and got it working on my printer.

[@LesFishingMoreCatching]

@@DinkaFox1 glad my comment helped.

[@EsotericArctos]

Just as a note, any ESP01 module with the right firmware flashed can be used. They are a fully standalone microcontroller and can be flashed with lots of different firmwares. The ESP-01 is a standard form factor. Also, you don't need the BTT Writer. Any FTDI style adaptor with 3.3V logic will work with this. Those things aside, this is a great tutorial if you want to add basic WiFi on 2.4GHz only to your printer very cheaply as the ESP-01 is very cheap. You will NEVER get an ESP chip match Octoprint because they just don't have the processing power. Octoprint runs on a Raspberry Pi or even more powerful computers, more powerful than the microcontroller on the printer controller board, let alone just the ESP chips. The ESP chips are great for basic wifi functionality, but if you use the full feautres of Octoprint, you might as well just stick to Octoprint and not bother with these as Octoprint can give you the full WiFi capabilities as well

[@jack-bjorn]

As always, you are the go-to. No one out there is as thorough as TT. Thanks Michael.

[@johndaly5958]

As usual a great tutorial. You are quickly becoming my goto source when I have issues/questions on my ender 3 pro. I bought my ESP-01 as a bundle with my TFT and it seems like it came preloaded with the needed firmware so I only needed to run steps 4.5.6. Still very good tutorial for those needed steps. If I had seen steps 1-3 I may have opted out of this upgrade as the cost of the writer+cables would have made this a $13 upgrade. I did have some issues post configuration trying to make changes to my preferences and creating macros but the problem was the on board chip memory usage was nearly 100%. I ended up removing the the favicon.ico and 404.html files (not really 100% sure what these files do for me) and that freed up enough space. Could probably also remove the index.html.gz file as well. Just a tip in case anyone else is running into issues with this.

[@tjones99]

I ran into an issue using this with the non TFT display plugged into the SKR Pro V1.2 board directly. Got it all flashed and looked great but nada on the M115 query. This is a Marlin thing... Marlin has two serial ports configured. One for USB (-1) which is used to send GCODE over USB (normal!) and one for the TFT (1). Now since you plugged yours into the TFT display, this worked because it was daisychained through the TFT display serial port (1). I was using a cheap non touch display hooked up using EXP1 and EXP2. So serial port 1 was not correct. Change 1 to 6 in the Marlin firmware and recompile and load on the SKR board and the SKR Pro V1.2 ESP01 connector is then active and connects. Working! Win! Thanks.

If you only need the WiFi and no touchscreen there is also a way. Took me some time to figure this out. I used a NodeMCU which has USB connection for flashing (no extra flasher hardware needed) and can handle 5V. I connected it directly to the TFT connector (VC, GND, RX, TX) and it runs great.

I just want to say that I love your channel. Of all the people that so called teach you how to on this site you are the clearest and you don't jump so fast that we can't keep up. How do those other people think they are helping when they go so fast that you can't catch half of what they are saying. Frustrating. Not everyone that watches these videos is a pro. SLOW down damnit. Not you though, you're great. Thank you. I have a request. I'm new to this stuff and I'm old. It confuses the heck out of me. I've tried and tried and I am not able to configure the firmware for my Anycubic Mega Zero 2. I installed the SKR-Mini 2.0 and the TFT35 E-3 3.0 . Nice boards but I can't get things going. Screen I managed to flash. But I need the printer itself set up. X=220, Y=220 and Z=250. I also installed the BLTouch and it has the stock extruder that runs reverse from what the firmware is running. I like the stock extruder, it works great, it is dual drive geared and I like it. Would you be able to configure that for me in a firmware i could simply download and flash? I'm about ready to just dump the whole dang thing in the garbage. I am tired of trying to figure out this stuff. If I still had the original boards I'd be putting them back in but I donated them to a school back east so I'm stuck.

I tried esp8266 based solutions in the past, and they were slow but functional, and wifi was still more reliable than the usb my printer had. Today, with raspberry pi zero w and similar boards for $10, there is not much reason for esp8266 on the printer anymore.

[@rods87175]

Great instructions! Easy to follow. I already purchased a few but didn't install any yet before watching this. I did do part of the install different. After I burned the firmware, I unplugged everything but the 3.3V & ground and completed the remaining steps while still powered by my laptop. Upon completion, I plugged it into the TFT35 on my Ender 3 and it was ready to go!

Those esp8266 modules are used in quite a few smart home devices also So not that anyone probably needs an excuse to buy a sub $5 ftdi, but if you do, or you want to find use for it after you upgrade your printer it can come in very very handy to write new firmware on smart home products that arnt suppose to be "hacked".

I would say, that if you need only Wifi printing with terminal - this is perfect tool for couple of dollars. Furthermore, if you will change old and barely working ESP--01S to atleast ESP8266 or even ESP32, you will have DHT support for temperature monitoring, relay control (or any other device with GPIO control) or WEB camera. Even more - you can add additional small OLED via I2C and that will be interesting device for less than 10 dollars.

[@Markfps]

I think it can definitely replace octoprint for me, as long as I can print something from the internal SD and have control over wifi, that would free me from using a raspberry and having to shut it down correctly to avoid SD card corruption.

This programming method makes this excessively difficult (looking). Please refer to Tasmotizer (load binary file and hit "Tasmotize" (program). if using a standard FTDI adapter, just make sure upon powering up the ESP-01 chip the GPIO 0 (zero) is held to GND for at least 2 seconds. This must be done prior to and during power up. If using the BTT FTDI programmer, it is handled by software. Much simpler. tool here --> ( github.com/tasmota/tasmotizer )!

[@Dude-ot9sb]

I have completed the instructions -- very good as usual for Teaching Tech. A couple of questions below however.... One of the comments posted about Checking the Box in the Firmware Update tool for the firmware file + entering 0x00000 was essential to post the firmware update to the ESP-01S. Completed the Web-Update on the ESP-01S with it plugged into the BTT CH340 Writer Tool 3.3v and GND only pins to power it. However, after placing the ESP-01S onto my TFT35_v3 board, the TFT Tools UI screen does not post a splash screen showing the ESP-01S is connecting to my home network, nor displaying its IP-address -- that was shown in the video and not what I observed. I checked my router for connected devices and found the IP address, then was able to log into the TFT ESP-01S homepage from a computer browser. However, I could not see any active status or send any Pronterface commands via the Web interface while connected to the printer via ESP-01S. The Serial comm subscreen showed G-codes being generated to send when pressing options on the webpage, but the printer didn't perform the actions. Questions: 1) How do I locate & show the IP address of the TFT35_v3 ESP module in the TFT35 UI sub-screens (without having to check my router for connections)? 2) Are there Marlin Firmware settings that I must enable so that the TFT35_v3 can send/receive g-code commands to the printer through the ESP-01S web interface? I have Marlin 2.1.2 firmware. Thanks,

[@Dude-ot9sb]

I have sorted out Question #2: In the TFT35_v3 config text file, I did not have UART port P2 set to a non-zero baud rate. That port is dedicated to the ESP-01S Wifi -- set P2 baud to 250000 in the file, uploaded the firmware + config edited file via SD card to TFT35, and upon start-up I can now see serial comms in the ESP3D web-interface and send gcodes. No additional Marlin updates beyond the original setup for attaching the TFT screen.

I have an Ender 3 Pro which I upgraded by installing the Big Tree Tech SKR Mini e3 v3 and the TFT 3.5 touch display. The Ender 3 is connected to my Raspberry Pi 4 via the micro mini usb port on the printer. This allows me to access octoprint. I just broke the micro usb on the SKR mini and my printer cannot access the web. I purchased an ESP-01S chip hoping to just plug it into the TFT or the SKR and have an immediate magical connection. Your video explained how this wasn't exactly a plug and play situation and though they are skillfully presented and detailed, your instructions on the chips' installation are way over my head. So I'm looking for any solution other than installing new mother board. I would greatly appreciate any advice or suggestions.

14:35 I'm having a somewhat difficult time understanding his (the github author) English, but is he basically saying to increase the speed of the file transfer rate over wifi of the printer is to not use that specific wifi module and to use another one that is a SD version? Second question: What does OctoPi offer that this doesnt? I'm a noob, so I have no idea what OctoPi does. From what I've seen in this video its pretty impressive.. The fact it has a camera (video?) option makes this a pretty sweet add-on.

[@peterjohnjoseph]

He has an entire Octoprint video. The camera settings in it, like time-lapse, are so much more advanced. Plus, with hundreds of plugins, there is unlimited potential to do more. Get a Raspberry Pi, control your printer, and when you inevitably get more, it will control those as well, from your phone app.

[@gazgadgets]

One of the problems I have with Octoprint (Which I use most of the time) is the comms speed between the pi and the main board (SKR Mini E3) causes the printer to wait for a split second sometimes for the next command. This is particularly true on printed curves. So a fast way to upload to the SD card would be useful. Looks like the wifi card might be a better solution.

Good video. I opted for the ESP-01S when I was building my Hypercube Evolution. A few observations: - Personally, being an old guy (LOL), the 8.3 filename is not a big deal. It's what I grew up with. (it's the old 8-bit DOS filename format. Tells us something about the board.) - Not sure why the upload is slower than on a standard wifi, but I'm not in that big of a hurry. - The Writer is a nice touch. I had to wrestle with the old Arduino-and-breadboard a bit to get it rolling. My personal opinion, the ESP isn't better or worse than an OctoPi, it's just different. (although the new OctoServer might change that opinion slightly)

[@willhutcheon4144]

Give " Tasmotizer " a try. I think your opinion will be forever changed. 1. Load Tasmotizer. 2. Select BIN and load BIN file. 3. Click Tasmotize. (it auto selects the correct pragramming optins and correct COM port unless you have multiple ESP chips plugged in.)

I wouldn't want to destroy either the screen, or the module by plugging it in backwards, and I'm not a fan of plugging it into the mainboard, because it overhangs the edge of the mainboard, which would mean I would have to cut or file an opening in the case to make room for the module.

So for the record, the black ESP8266-01 boards have 1mb of flash. Those instructions are made for the 50kb blue versions. That download tool tells you to select 42kb! You'll be losing 50kb of storage space by doing that! Check your esp before doing this!

[@SonicBoom247]

do you have an updated video on the SKR 2 and the ESP-12S? that is what i currently have and although i have it broadcasting simply by connecting it to the SKR 2, i cannot connect to it.

[@johana200]

Would it also be possible on the Mingda Max, does the motherboard also have an ESP-01S terminal?

If you are interested in running Marlin + ESP3D natively on the ESP32, here are some boards: github.com/maplerainresearch/MRR_ESPA/ github.com/maplerainresearch/MRR_ESPE/ These boards require the ESP3DLib by Luc (author of ESP3D) which integrates ESP3D with Marlin (instead of ESP3D communicating with Marlin via UART). github.com/luc-github/ESP3DLib This allows features such as over-the-air update of Marlin firmware, plus all the other features of ESP3D. File upload is also a bit faster since the data is being written via SPI to the SD card directly, instead of being sent via UART to Marlin, and then Marlin having to write the data to the SD card via SPI. The "grandfather" of these boards: github.com/simon-jouet/ESP32Controller/ (Simon was one of the main people who brought the ESP32 HAL to Marlin)

Key question for me (and why I found this and got here): Would BIQU B1's stock filament runout sensor still be active for a job launched this way? Since a filament runout sensor's feedback is not supported via serial communication, jobs launched from Octoprint have no filament runout protection. i suspect the same kind of issue may be at stake regarding the power loss resume feature as well.

My TFT do not recognizes my ESP01. It starts up, I can connect to the IP and full interface. However, it appears not finding serial port. Anything in Marlin or any specific configuration?

[@rikes7855]

You don't show configuring Marlin for the ESP-01S. Other videos, Chris R. and Chris W. show changing SERIAL_PORT to 3 and defining wifi support in Config Adv. But Marlin Support says defining wifi support in Config Adv is not needed. So I'm confused, everyone says something different.

[@alfredanil]

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.

[@roccocroce]

Getting Unknown Command M153 now that the module is programmed and installed. The flasher didn't work, but tasmotizer worked first try. did the net login config and uploaded everything. just never seen this error before. it displays in the little status box where yours had the IP address. ://

[@roccocroce]

error unrelated to WIFI function. wifi module installed into tft and in settings the wifi functionality has to be enabled. did this and now i get the IP on boot ( along with that nonsense gcode error message but ignoring for now ).

[@zdenek620]

Hi! I need advice, I have BTT SKR 1.4 for, in win10 I can't move files, it still reports "only v8.3 files. I have .gco files. In win 8.1 it worked, but it reports that there is no TF card. When I read from TF card on the board, it says there is no card.I have to use SD slot on the display or USB.Thank you.

[@SomedayStreams]

can you do this on a btt skr v2 without the writer? i have the adapter but nothing else?

[@jawa6988]

Everything went smoothly flashing, but then After installing in the printer, it showed it's face ONCE. I logged in as instructed, copied the 3 files and haven't been able to connect back to it again at all. No matter how many times I flash it. It will flash, I can connect a device to it, like my phone or computer and ping it etc, but no response in a web browser. I don't know how to place files on it if I can't connect through the browser. This is super annoying. Can't we SSH into it or something??? The device seems to be working, but missing required files and doesn't seem to put the first-run config page back. HELP PLEASE

[@matthewstrangwood8463]

you've done so many videos on boards, whats the best one !

[@x_jaydn]

Hey Michael, How would I go about programming the BTT ESP-12S (ESP8266) modules for the SKR 2.0 Rev B STM32F429VGT6? Are "platform", "platform_packages", and "board" correct?

Just subscribed for respect to the jacket.

[@dickysoeliantoro5576]

Hi, one question. Using SKR E3 turbo, TFT35 E3 V3 and ESP-01S. Could I get everything to work without buying the writer module? Because nobody selling the writer module here in local store.

[@digital0785]

i keep trying to install the firmware but it keeps giving me a chip sync error but i is there any way to know if it's actually using the com port selectect? because if i change the baud rate it doesn't change in the CLI

[@Bajicoy]

I am running into trouble with the btt writer where it is looking for drivers but I don't know how to install them

[@osky087]

can you get reprap fw working with this wifi adapter? or will you need one that connects to the exp ports on the board? I recently got a biqu b1 printer and i would like to get reprap going like it does on my ender 3 with the biqu e3 rrf board that has built in wifi.

[@douggjoseph]

Any one know a way this flashing process can be done either on a Mac or in a virtual machine running Windows? I'm trying to create a com port (serial port) in Parallels that can properly access the writer in USB port, but cannot get it working.

[@mattgreen6895]

Thank you for this. Any chance of a video on how to get there(BTT)Filament sensor working as I believe this is another thing people are struggling to get working

[@skrebneveugene5918]

Was trying this week ago and Nothing happens when i trying to upload index. Html... Esp free space doesnt change... Says 490kb free, no file appear in file list(( was trying several esp01... Nothing works

[@joaonobre5705]

hello I installed a new board on ender 3 but on the lcd it appears written (no printer connected) that could be already reviewed the material links I used was: BIGTREETECH SKR Mini E3 V2.0 - 32-bit control board with TFT35 E3 V3.0 pantalla touch RepRap Smart Controller repost panel for printer ender 3 ..... I can only work with Marlin bugfix 2.0.x 2020-23-03 has 2 systems installed ... Marlin and Bigtreetech touch mode ....

[@leafyon]

Jesus christ I'm so glad octoprint through a raspberry pi exists

[@MONTY-YTNOM]

This could be handy for the printers that won't allow Octoprint to connect

[@brian2329]

Would like to say I have learned a lot from your channel in the short time I've been 3d printing. Only sometimes it's not very clear like the Rx/Tx crossover I found that out from another tuber. Also going from an unplugged control board but then going to a fully functioning printer tft that the wifi module 'powers on' with? how do you know it's powered on, does it have to be powered by main power (12/24v) or will it work with usb. Mine doesn't transmit it's own wifi that's why I'm asking

[@stefan200689]

Thanks! I've been struggling for a long time to get it to work, tried swapping TX and RX, and it works!!

[@hfog]

Another great video. Thanks Michael. One thing. Have you tried compiling the TFT firmware with #CLEAN_MODE_SWITCHING_SUPPORT enabled? That enables the TFT to continue forwarding messages received from its serial ports on to the printer even when it's in Marlin emulation mode. I haven't tested it with the wifi module but it should allow the wifi module to work in either mode.

[@Limited113495]

interesting video. So maybe it would be better to connect my printer via a resberry pi to upload my prints from the pc?

[@9TDF]

I'm trying to set up a DIY I3 with the BIGTREETECH BTT002 V1.0 32 Bit Control Board for I3 MK3 and BIGTREETECH TFT35 V3.0.

[@bil111978]

Followed to a t, wifi broadcast, did setup wizard on pc, then it wouldn't connect. Now it's not broadcasting, pc's not finding signal. Tried process again from start, redone firmware again, and still no broadcast from wifi chip

[@tiagomiranda84]

Hi mates, I flash the firmware, plug on printer, but then i cannot see the esp broadcasting signal. Somebody help here?
