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

- I’ve had plenty of requests to make a guide on adding a Bigtreetech ESP-01S WIFI module to SKR boards and TFT touch screens, so here it is. While nowhere near as good as Octoprint, it is very cheap and could be useful. The situation is sure to improve thanks to the developer behind the firmware and web interface.
These steps may be compatible with other ESP8266 hardware but there is no guarantee.
This BTT writer and BTT ESP-01S were sent to me free of charge with an SKR V1.4 Turbo board for the purposes of making this guide. All opinions expressed are my own.

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.
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.
@@DinkaFox1 glad my comment helped.
Just wanted to say THANK YOU!! Loving your material and your doing a great service for the community. Wish you all the best!!!
As always, you are the go-to. No one out there is as thorough as TT. Thanks Michael.
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!
This is the video that I wanted to get! Thanks Michael! I have all the necessary parts sitting at home.
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.
I was literally looking for this yesterday and now you are here
and we wont see this video again till youtube suggests for us to watch it in ten years.
Thank you! Thanks to this video, all my questions have been answered and I have a great environment, really. Thank you.
Your instruction quality is incredible. You deserve to be much larger than you currently are.
this week i'm heavily upgrading my ender 3 based on reviews you did. because well i need it and well I need it quite since it's going to have to run like a foot away.
I purchased the screen and wifi module with the board, I returned the screen and wifi module.
It use Octoprint instead.
The board is a wonderful upgrade.
Thanks again, Michael!!! I bought a few of these and was struggling!
Me too!
@@jeffweiss2131 Dumbass bought this......He will make another video and it will ber BTT new board with onboard wifi anyway.....All this effort......I bought things like this before and then as soon as i finish setting up.......Go figure....they bring out a new latest and greatest board with new features.....Waste of time....the money is no issue just pointless.
Congratulations on the video, beautiful SENNA jacket, thanks for remembering.
thank you for this. I have been looking for these instructions for a long time.
Downloaded the files, now it is time to read!
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.
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
Nice video, I was thinking of doing this at some point and now glad I didn't. :) I'll check this off the list.
thank you so much for all the guides
Sweet. I've been meaning to get mine working. Thanks for the video
It's interesting to see the old MS-DOS 8.3 filename limitation in 2020....
It wasent as much DOS as the FAT filesystem from what I remember.
@@davey3765 DOS had a 3 character limit which is why .jpeg is .jpg in so many places. as well as many other programs still sticking with 3 letter extensions even though it isn't really relevant anymore.
@@gg-gn3re this is because of some tiff between marlin lead developer and luc (author of Esp3D) where marlin maintainer says "the file name limitation is a feature not a a bug" !! can you believe it !!
sadly, this is apparently a Marlin limitation :
@@GameProgrammer79 memory constrained devices can't afford thicc filenames.
Stopped by to say awesome sweater!
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.
What a fantastic video. Thank you for this
Old but a good video!
If anyone is interested, it works almost exactly the same with the ESP32E/ESP32U, only you don't need the flashing tool!
Unfortunately, my comment explaining how it works, and the pin assignment was deleted.
So you have to write to the BIQU support about the pin assignment!
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.
Great step by step tutorial.
And really nice Ayrton Senna Jacket :-)
I love the SKR 1.4 I updated my Ender 5 for this board and can't recommend it enough, I have asked them to re-orient the ESP-01S port somewhere else on the next revision of the PCB
Some dupont connectors and hot glue would remedy the situation.
Really cool that they put this right on the board... just one clarification...the ESP 01 isnt a wifi module....its an entire microcontroller, that happens to have wifi... Yeah its probably splitting hairs, but dont undersell this cool ass little thing.
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.
any ideas this keeps popping up when use touch screen while printing marlin mode works fine
M73 Q84 s7
this its something to do with print percentage
any ideas how to stop it
thank you
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.
awesome guide! have you ever seen an issue whereby setting temps, or setting temp auto-reload on the temp widget, hangs the interface permanently?
Great video mike
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.
First off, thank you very much for making this guide.
Very interested in making this work correctly, but I'm finding that there seems to be a limitation to 8.3 filenames. I know that my firmware is not limited that way, as I use long filenames (And the .gcode extension) regularly. In fact when converted to 8.3, I can't seem to make them work, so it's not even particularly good at what I mostly want from wifi connectivity to my SKR Pro 1.2 board.
Everything else, including the Gcode console and status monitoring seems to be working perfectly.
I've read comments that the 8.3 limitation is a limitation of Marlin, but since I can use the filenames if I sneakernet the files to the printer, why can't I upload them through the ESP8266 firmware?
Is there a newer version of the firmware that will not insist on 8.3 filenames?
Is there an alternate that will work through the regular LCD interface? ( FILENAME.GCO does not appear to work )
I used a D1 mini ESP8266 and added to my A10M , it uses 5V and TX and RX. connector on main board. not really all that usefully due to not being able to use internal SDCARD because so slow, but great for using terminal without having to plug in USB cable, or doing movement / home moves. but because my printer is on same desk as PC its easier just to use LCD menu.
but it was a fun project to build and use. once SDCARD use is updated it be a lot better. The macro information and setup was very useful as i have not done macros but now know how :D
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".
Interesting as always
Thanks for sharing :-)
thanks, this is very valuable information!
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.
can you please send link to any tutorial?
i recently added the same to my skr 1.3
just flash esp3d onto a esp-01s via arduino ide and ftdi adapter, and hook it up to the "TFT connector" (right side of sd card slot, above aux 1), its pinout is 5V GND TX0 RX0 RST.
rx/tx can be hooked up directly, just 5v to 3.3v via external dc-dc or linear regulator.
the digital i/o pins on the LPC boards can take 5v as input but its output is 3.3v, no need for a level shifter.
bridge EN/CH_PD and RST on the esp01s to 3.3v so it can boot.
thanks for the tip! Is the documentation available somewhere?
Got an immediate like because of the SENNA jacket.
Thank you. Thanks to you, I succeeded.
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.
Can you please explain the "ESP3D Firmware Update" button @12:22. My understanding is that the wifi module works out of the box and then use Firmware Update to flash the latest firmware. Hence no need for the BTT Writer.
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)
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.)
My Ender 3 Pro is getting the MAXTEMP ERROR whenever I start heating either the hotend or the bed.Whenever I turn on my printer the nozzel reads at 298 and the bed at 147. I Tried replacing the thermisters on both the hotend and the bed. I replaced the hotend. I also reflashed the firmware. The motherboard I'm using is the stock Creality V1.1.4. I also have the BL Touch attachment. What else could be giving me this error and what other options do I have other than replacing the motherboard?
how about when starting ah print from SD Card in TFT Slot? would the WIFI Interface display the progress of the print?
As a Brazilian that lived and love Australia ( Perth is still Australia right? :D ) it's super cool to see you in that Ayrton Senna Jacket the man was a class act and the main reason F1 was cool to watch in my childhood (also his battles with Mansell and Prost), I stil remember the watching San Marino in 94 super clear even now, such a sad day.
He was a excelent pilot but also knew a lot about cars and mechanics in general even without being an engineer.
Keep up the awesome work, this channel is the best 3d printing resource on YT, I always watch it even when it's related to printers I don't care too much just because it is so well done. I always learn some stuff,
Will it be possible to use ESP-01S after the purchase and installation of BIGTREETECH TFT35 V2.0 on the SKR MINI E3 V2.0 board?
Great hoodie!!!
there are options in the tft35 firmware to keep the serial connection alive. after compiling and uploading all commands to the esp go through including m117 commands in marlin mode on the tft.
Is it possible to update the WiFi via the TFT35 V3.0? My TFT35 sees the WiFi module, but I can't make any changes to it. Does that mean I'll need to get the writer to work on the module? Using the ESP 8266.
Starts video - 666 views - hears Shotgun loading with malicious intent.
Great video as always.
Will you be adding this to your Prusa Mini seeing as this is the WiFi chip for that as well?
just to know, can I use a ESP-01 (non S version). Mistake on my order and now I have a ESP-01 :(
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.
Will never forget 1994 San Marino.
Was that the one year San Marino ever won a game?
@@JasperJanssen No it’s when Ayrton Senna died in a car accident (Formula 1).
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.

Any chance you can do a video on installing the Bigtreetech Relay 1.2 on the tft35 and or the SKR 1.3
Hi I am new to 3d printing and was wondering about some sources for filament especially in aus? Also what to look for in good quality filament and how to tell the difference between bad filament and good filament? What type filament would be good for what applications? Thanks TTech
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
hello. what is the conector to attacch the BTT mini ups 24v to the TFT35 E3???
Could you make a video on how to easily transfer all the changes from old Marlin firmware [e.g.: for custom 3d printers] on to the new version of Marlin? Seems like every time, we have to go and find the parameters we need to change and do them manually 1-by-1. Thanks for very informative videos.
This is great because when I bought my TFT35 it came with the WiFi board but I didn't know what to do with it since I couldn't find any info for it.
Also, may I make a suggestion for a future how-to? Upgrading from the stock thermistor to a PT100 thermocouple. The standard thermistor in my Ender 3 recently failed so I replaced it with another of the same type. What I really wanted to do was to replace it with a PT100 type thermocouple but the SKR Mini E3 board doesn't support it. I know an amplifier adapter board is required but not too sure about reprogramming Marlin to make it functional.
hmm i got a second printer and wanted to try this rather than octoprint since it was so much cheaper but i cant get it to do anything. I got the firmware flashed and the web files uploaded and can connect with my pc (wired CAT6) and phone (wifi) and go through preferences and have set a static IP and all but it does not "see" any info from printer and cannot move any axis or heat the bed. I am running it on a Sovol SV01 with a skr mini e3 v2 and the tft35 with the module plugged into the tft.
On the printer tab i clicked refresh and then only get the words Label, Value, and Help with a thin black outline like they are buttons but thats it?
Fantastic video, worked a treat. Any idea why i have the coordinates keep scrolling down the command box?
You showed how to connect this to a TFT35, but will it plug into a TFT70?? The TFT70 does have an 2x4 port which is labeled ESP01. If it will work on the TFT70, which direction should it be oriented?? 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.
I like your Ayrton Senna jacket.
Nice video.
Can the ESP8266 or ESP32 module be used with Creality 4.2.2 board (Ender 3)?
If so, can you please make a video?
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
Just a heads up the TX and RX are silk screened the wrong way around on my writer board.
Very cool. I’d love to put WiFi on all my printers.
Everything went smoothly until I tried the m115 command. I didnt get a response. Is there something I need to change in the firmware to allow it to communicate with the printer?
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?
hi. it can work with arduino mega + ramps +marlin setup or is only for skr mainboard? thank you
Just subscribed for respect to the jacket.
I have SKR Mini V2.0 and TFT35-E3 V3.0 with latest firmware. Everything works except SD Upload fail with Error: Error: No Checksum with line number, Last Line: 1 Resend: 2
Any tips?
Love your videos any chance you're going to get the Ender 3 v2?
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.
can you do this on a btt skr v2 without the writer? i have the adapter but nothing else?
Hey Micheal ,BIGU have put out the SKR mini e3 V2.0 with easy sendorless homing , dual z support and thermiator ahprtage protection circuit , can you do a video going over and setting up the board and verifying the thermistor protection circuit?
Thanks for the great info! Is there video on how is integration of this TFT and Octoprint work? If not, can you create one? I mean if you start print from octo will it show progress from TFT? Can you choose to print from TFT SD card from octoprint interface? Thanks!
There is a plugin in cure to use this adapter built into octoprint
i did all and then i dont see the ESP3D on the wifi , my network is 10.0.1.xx is that why ? if not what can i try to make it work ? thanks
you are à genius thank you very very much.
Can I flash esp01 without this usb flasher? for example with arduino ? I have SKR 1.3 and tft35 v3..
I was going to ask if it had any benefits over octoprint and you answered that pretty fast. Been using octo for years now and won't ever look back even if the boards are $35+ and with a high gain wifi adaptor your printer can be pretty far from your router.
Thumbs up for the Ayrton Senna hoodie! If I'm ever able to emigrate from Brazil, Australia will be my first choice (if the Chinese don't buy the whole country first, that is😂😂 ). Thanks for an other great video!
the Queen has secretly sold Australia to the Chinese but it's only official when she is gone for good. She will last long because she already has the money.
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.
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.
What use are PINGS? Can you manage or adjust them to get better prints? My machine seems to have quit one job because “ping=.25?” I have seen long lists of ping results, to what end? J
Thumbs up for the Senna jacket.
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.
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.
is it possible to attach the camera as well to record timelapse ?
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
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.
yoooo..!! I need that hoodie!
the 8+3 file name is from the old pre fat32 days.
The Esp32 has the same file issues.
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
Thanks! I've been struggling for a long time to get it to work, tried swapping TX and RX, and it works!!
