I made it!!! Now my $2 ESP8266 is priceless.!! I used a FTDI232 instead on an UNO. Thinking I could use the 3.3v directly. Everything went well, until I realised I still need the voltage regulator when hooking up the module to the main board.
I'm using octoprint for these day to day tasks but I use a ESP8266 with esp-link firmware for over the air marlin flashing. Also the 3.3V step down converter is probably not needed. The ESP8266 can tolerate 5V
@@ChrisRiley I already ditched that for the octoprint firmware flasher plugin (but it requires proper bootloader (instead avr isp method) on the printer, manual avrdude installation on the pi and much patience finding the correct settings). So overwhelming sometimes when so many different roads lead to rome.
right chris the only thing i did not do was use the regulator but now i have the regulator its all hooked up as per your diagram im getting the same this, also the led is constantly lit on the board aswell in ur explanation you say it flases one but mine is on all the time
Nice instruction again! The ESP is a 3.3V device, including the serial signals, while the control board is a 5V device. Wouldn't the 5V TX signal from the mainboard damage the ESP?
I'm using the nano. In another video said the nano reset has to be set to ground to program the esp. This works doing that, I have the 4mb esp-01s, it uploaded the CheckFlash sketch and reported config ok with 4mb flash size selected.
Have everything up and running, with help of your video. Now it runs on a Infitary I3 with a custom HY_BASE_L v1.0 board, which I adapted (tricky!) to have the same AUX1 connections as the RAMPS 1.4 board. One final remark: in your video (at about 15:15) you make the final connection of the ESP8266 to the AUX1 connector of the RAMPS board. For non RAMPS users it is perhaps not clear that in this situation you connect TX(ESP) to RX(RAMPS) and RX(ESP) to TX(RAMPS). Thanks again for the video.
I've been using one of these for a couple of weeks now and although it "works" there are some big and annoying drawbacks. First being very few programs have the ability to print to a wifi-serial port (most of them expecting it to be just a serial port device) - there's only Repetier that I've managed to get too connect to it directly. And then comes the second disadvantage - there can be considerable lag over wifi which shows up as it being unable to fill your printers buffer fast enough resulting in the printer stalling while printing. In short, if your system works such that you can upload to SD and print from there (mine doesn't for reasons I've not yet figured) then this is cheap and simple way to SLOWLY upload to SD card, but don't really expect it to replace a USB lead if your printing directly.
@@ChrisRiley My Repetier Host will connect to my wifi (ESP-01s on SKR-PRO) printer via IP on my local network so I just use it that way. I use the data port 8888 and it functions just like using a USB port. I think Cura will do the same.
finally got it, it was very difficult to me to make the adapter module for my RAMPS 1.4, but finally maket and works like a charm....cheap wireless 3d printer!!!! thanks Chris!
Hello Chris, in the schematic drawing that you sent me the RXd of the esp is connected in the D2 of ramps and the TXd in the D1, check this link, because what I was reading would be the opposite and I am in doubt to call in ramps here.
@@ChrisRiley Thanks, but it did not work, the esp was red light on and the LCD was saying connecting and then started to give a bug in the ramps and it was restarting, I will redo everything.
@@TheNikakz Interesting some pinouts call it d0 and d1, others call it d1 and d2. No matter what they are called they are still the top two right pins on AUX1.
Hello Chris I bought a new esp8266 and at the moment it worked perfectly. Could you please post a video of how to add the "camera" that has the option in the firmware? I don't know what type of camera or how to put it. I didn't find much on the internet about it.
@Hindo Y. Yes, upload sketch, reset, then in tools hi ESP8266 sketch data upload, then reset, log on to the ESD3d via wifi and the wizard will pop up. I am trying to find a work around because the ESP3d instructions for the new version says you shouldn't have to do the sketch data upload, you can use the web interface, but I can't get it to work that way.
@Hindo Y. For me it worked with the v1.0. This is how i did it: 1. Set Flash Mode: DIO 2. Set Flash Size: 1M(128K SPIFFS) 3. Set CPU Frequenzy: 160MHz 4. Erase Flash: All Flash Contents Then i flashed the ESP3D v1.0 to the module, reset the module and then hit ESP8266 Sketch Data Upload (even though if the install instructions here:github.com/luc-github/ESP3D/wiki/Install-Instructions tell that it isn't necessary anymore). Then power off the module, remove GPIO_O to Ground jumper and power back on. Then the setup window on my laptop appeared after the wifi connection to the ESP8266 was established. Chris Riley Thank you for this video!
Sooo...would this work with the WiFi module included with the ender 3 BIGTREETECH touchscreen? It looks like the exact same part. This video is the closest thing I’ve found to setting it up. All I’ve found is instruction videos for raspberry pi octoprint or other self contained modules. Even had to take a 50/50 shot at which way the card plugged in to back of screen.
This is an awesome DIY! What is the bread board you're using to connect things temporarily by pushing it in. The white breadboard with the pins. What are those called where there's some connections between the pins and is good quality for continuous use like this..? Thanks!

Started in on an esp32 on a 1.1.4 board... I think I have the pinout. The web gui works good, but I have no idea for the actual interface to the board because I have not soldered anything to the pins on the 1.1.4 board.
Hello Chris, I can use this: Mini module voltage regulator AMS1117-3.3V; The module integrates the regulating capacitors and a voltage indicator LED; Recommended voltage input: 4.5VDC to 7VDC; Typical output: 3.3VDC; Recommended maximum output current: 800mA; Supports up to 10VDC at the input, but with a heatsink Thanks

So once the IP is established, can the independent ESP's being added to a management software like Klipper or Creality Print? I want all my printers on one software and it makes sense that I could add IP direct to the Creality Print Slicer and upload from there direct to my machine. Thanks!
I don't know that you can, you still have to compile it. If you are using the Arduino IDE you might be able to use the IP as an upload port., but I probably wouldn't recommend it.
The board I used it the cheapest option. You can run this software on any ESP32 or 8266 now a days. So pretty much everything is better than this board.
I used nodemcu and I could see the web interface when I opened the ip of nodemcu but I couldnt upload any gcode in it . What is the problem ? what am I supposed to do? please help me
Followed your instructions, and it worked great. I think I still prefer octopi on my $14 orange pi zero, but it’s still a nice option. I like your videos, so you have another subscriber.
Chris Riley I like the esp solution as once gcode is uploaded nothing should interfere with the print. With Octoprint I have gone through periods where the usb was playing up and the printer kept micro pausing every few seconds. Octoprint also has the issue that when left plugged in my ramps board the lcd is still lit even when the printer power is off.
Great video--hey Chris howzabout an updated 2020 version of this tutorial with a USB CH340 and SKR1.4 and latest ESP3D? Michael TeachTech's was a little basic, I think you could improve on it. Plus I think there are configurable files for VSCode? Thanks man
Ok. for ESP3D-2.0, copy the whole tree to your projects folder, then also copy the libraries folder to your arduino libraries location. Then under examples you can load the CheckFlashConfig. Once thats ok, load the new ino project 'basicesp3d.ino'. Then download the ESP3D-WEBUI files, once you connect to the basicesp3d webpage over wireless you can upload the index.html.gz package and begin configuring the client. I didnt have to load any blank sketches and the SPIFF is not necessary anymore (its built in).
@@ChrisRiley Should have a Makerbase board? Serial pins broken out for the Makerbase TFT. However if it ships with a TFT touchscreen controller, the serial pins are occupied. The external USB is then served by the Makerbase TFT, which is not fully command-compatible, and since USB-serial interface is implemented on board the STM32 processor, serial passthrough is not accessible externally. It is my understanding that Makerbase ships its own ESP8266-based WiFi upgrade module that goes into the TFT screen, but the firmware on the screen needs to be reconfigured or modified. Also not sure whether the WiFi functionality is actually any good.
@@ChrisRiley all Makerbase boards have an 8-pin keyed connector, which is laid out like this: 5V GND TX RX 5V GND NC NC (key side here) It's usually helpfully silkscreened on the back side of the board. It allows Makerbase TFT to connect, which is a spooler emulator with a colour touchscreen. But you should only be able to use either Makerbase TFT or any other kind of serial without interference, not both. It's connected to the serial-USB bridge via a bunch of resistors, such as not to burn up either of the chips. If there's anything the Makerbase Gen.L doesn't lack it's the resistors - also connectors for just about anything you might think of.
@@ChrisRiley i tried to change but when i try to enable serial 2 firmware is not compiling Serial 0 is used by USB,serial 1 is Y-axis min & max , serial 3 is Z-axis min & max But serial 2 is not enabling
I was hoping to toss this great idea into my ender 3 as well, even spent 6 hours trying to get the esp8266 modules flashed before giving up and moving to a D1 mini, which took about 20 mins to setup. Then I tip over my E3 and see there's no ramps board lol. Did you ever find a wifi solution Vinston?
Damn Chris, you were faster! I was currently planning on doing this upgrade as well, but with a different ESP8266 module. As always, your videos are very educating and easy to keep up with!
There are, indeed. I hope to get a video together soon (that's always the longest part of the project for me, and together with my limited free time it explains the low frequency of my videos)^^
Hi Chris, I am able to make the module show up on my laptop and the WebUI pops up once I click on it, but when i try to connect to the module after I have it set up in the WebUI, I cannot. I have the module set to Client Station but it still shows up in my wifi list as a device to connect to, should it? Any ideas on how to fix this? Thanks.
@@ChrisRiley But when the setup process opens up in chrome and I select Client Station, it seems to stay connected as an Access Point.

Hello Chris Riley. I´m having problem to write because my laptop give me a serial error. Do you know what happening? My LED still on when I connect 3.3v not only one blink. I follow step by step but doesn't work!!!
@@ChrisRiley Doesn't work. I connect all the wires correctly but when I access by IP and send a command doesn't work. The only thing happened was my LCD lose a little the bright. Do you know How can I do to work?
I'm wondering, would this work with the BTT SKR Mini E3? It doesn't have an aux header like the RAMPS board you're using, but it does have a TFT labeled header, which has RST, RX, TX, GDN and +5V. Seems like it should work, right?
Hey Tim, it seems like you should be able to make that work. I don't know a lot about that board yet, I do have one and I should start my testing soon.
@@ChrisRiley Hi Chris, back again with a question: Could it be that I have to activate the TFT header on that board? The ESP is working as it should: I can see that the proper gcode is sent (while I have the ESP plugged into my PC), and the web GUI works while it's plugged into the printer (so 5V and GND do work), but the printer doesn't respond to any of the commands. It also doesn't show the IP address on boot, like you showed. I've already tried swapping the TX and RX lines, but no luck there either. Could it be that the 3.3v signal level is too low for the SKR Mini E3 (not sure what if your RAMPS board was made for accepting 3.3v logic?)? Is there something firmware-related that has to be changed for this to work? As always, any help would be greatly appreciated.

Mega clone have a bad habit of not having very good 5v regulators. Try plugging in the wifi to ramps then cabling the board you USB to get an additional 5v source. See if that works.
hello sir, i need u suggestion on my school project .i want use board skrv1.3 + tmc2208 motor driver and want add wifi. what i suppose do on step by step.
Hi Chris, thank you much for the good tutorial. I certainly would prefer this method over the Raspberry Pi, and I do have a few Wemos D1 Mini sitting around. The major obstacle is, however, to look for the Rx/Tx lines from my Ender 3 mainboard. Can I use the ones on the ISP socket, or do I have to look for them somewhere?
On an ANET, you would probably have to hack the LCD cable to make this work. You would need to use a lot of those PIN's. Not sure which pins they are, but it's going to be a lot of work. The performance isn't very good with these modals. I would stick with the Pi method if I were you. Maybe grab a Pi Zero W and integrate it some how.
thank you it worked good, but i have problem connecting to the printer when i open the web page and send some command to the printer, it didnt move or do a thing oh and one more thing, when you hade a problem uploading the esp3d file to the ESP2866 you have to check the Erase flash to All flash contents, under Tools menu.
So, that board you're hooking the 8266 up to - does every 3D printer just happen to have that interface? I have a CR10 - without opening the control box/power supply, all I see is an external USB plug. All I really need is the ability to wirelessly upload prints, so this project will work for me
We touched on it in the stream, but all printers probably have access to this connection it's just going to be a little difficult to find the right point to plug it in on some models. Not sure on the CR10, I can take a look.
Hy Chris, i'm loving this tutorial, managed to prepare the esp, and next up is connecting it to the ramps. Would this work with a voltage divider made with resistors? Do you have a wiring diagram between ramps and esp-01?

You should be able to just connect it straight up to USB, then make sure you select the right flash size when compiling, more or less same procedure...compile the .ino, upload, then upload the "webpage" data, then it connects with the TX/RX pins on the board...still need to wire in 5vdc and GND Also looks like a good candidate for the wifirepeater image too

What version are you both using? 0.999? You need to make sure you load you filesystem before you load the sketch. Make sure you use the same library versions I do in the video.
Chris, after juggling I managed to configure, but I had to do differently in some parts, change from flash mode DIO in one and then QIO to the other, CPU frequency also to 80 in one and 160 in another, then I got the same way put the SPIFFS in 1M 512K, was trial and error to set up and I did not understand why all this. Now I was in doubt on some configurations of the WEB interface, could make a small video demonstrating this, for beginners as I is something crucial, for example IP is set as static, this is or would be DHCP, printer settings, etc ... I apologize if I bothered you with so many questions, I have a lot to thank and I have learned from you it is difficult for a beginner and with the language barrier it gets more complicated. Thanks
Chris, one last request, I did not understand the connection scheme of ESP with AMS in ramps, even for what I downloaded in your google docs, could you send me this link? In its drawing the 5V of the ramps Aux1 goes on the VIN of the AMS, GND AUX on the AMS 2 and the GND of the Esp (that is not GND is out) and the AMS 3 that is GND goes in the VCC of the Esp, I was confused with these connections.
Cool, already googled how I can connect this to my stock Creality board. They sell uart to usb adapter with those, I guess I can program it without Arduino then.
Hello, Nice video!! I'm using the same version that you are using. But when I'm going to the Dashboard, I cant send any commands to my printer. Do I need to change something in Merlin? Could you send me the merlin file that you are using?
That has been so long ago I don't know where that config is. If you are using Marlin 1.1.x then you don't have to change anything. If you are using 2.x then you have to add the second serial port in configuration.h
@@ChrisRiley yes, but I followed another tutorial, my module needed another flash before this firmware. It is a Chinese tool, called ESP8266_Flasher_Tool, now it works nice. Thanks for your video, you made me put this on my printer. Works nicely!
Hi Chris great video. Thank you for everything you doing. Can this be used on a Trigorilla V1.1 board ( on Anycubic I3 mega). I checked and on the board I have 4 pins available GND , 5V , TX3 and RX3 ( and UART next to them). Also do I need to install Marlin or it will work with the official firmware? I tried the OctoPi variant on a Pi4 4GB but I have problems with my prints and think the reason is a bad communication between Pi and printer. Same G code from SD card came out perfect but from OctoPi I had a lot of strings , bad retraction and miss steps. The only reason I try this is because the main thing I need is to have remote access to monitor the printer ( mostly temps ).
For monitoring this might work for you, not so much on printing really. It should work on that board, I don't think you will have to change the firmware, they use a version of Marlin, just not sure which one.
Fantastic video! One question though: In the ESP3D Github repository, under Install Instructions there is an EDIT that says that the SPIFFS Tool is no longer necessary because since FW version 0.9.99 there is a self uploader. So that means that when I have everything ready and upload the FW (1.0) into my ESP8266 the sketch data will be automatically uploaded with the FW? Can I completely skip the SPIFFS part of your video?
Well, it says that is will work with the self uploader, but I can't get it to work. The only way I can get it to successfully upload is by loading the data first. Give it a try, but I have had no success.
You could use GPIO pins on the pi if you new the right pins on your mainboard, but that's about the only thing I know. Is there a reason you can't use USB?
Hi Chris thanks for the aweasome tutorial. I just have one question I went to the Github wiki for ESP3D and they add a couple of resistor CH_PD and RX pins they also conect RF to ground on the ESP8266. Is it needed or with your setup I fine?
i order a esp8266-12e waiting to ship from china, it got a build in AMS1117 voltage regulator and use a 5v usb phone charger to power up the esp, so do i need to connect esp 12e the gnd to ramps 1.4?
It would kind of work. The current isn't high enough. It would probably work when you were configuring it, then fail when trying to connect to the wifi.
Yeah, the issue is only when I reboot to connect to a AP. Using the module in captive portal mode works fine, everything seems to be configured correctly (although the password is shown as the wrong number of "*"'s), just once I've done that, I power down and reboot.. and ....nothing seems to happen other than a few flashes of the WiFi led. Also, its supposed to be reset-able by grounding GPIO2 during boot to reset the eeprom setting - that's not working for me either, so I'm starting to think the software is more buggy than it should be.
They are pretty much the same concept, but Octoprint is going to be much faster and have a lot more plugins/features for it. The ESP option is a lot cheaper than the Pi, but not as fancy.
Hi Chris, great video and a whole bunch of information. In your video it looks like being so easy to conect the ESP to AUX1. Did you change anything in Marlin? I tried to conect my NodeMCU ESP12 to my anycubic Kossel having a Trigorilla board. This board has an UART3 port using D15 as RX3 and D14 as TX3. Ground and 5 V is workig to drive the NoedMCU, but I can't get the data lines working. I tried to use Serial_port 0 to 4 in Marlin 1.1.8 but with no help. Do you have any clue? Many thanks and dear greetings Simone
I didn't have to change anything in Marlin to get the Wifi to work. As long as those pins don't interfere with other serial traffic you should be fine. In the PINS.h file you might try swapping out the pin numbers to use the same pins as AUX1 normally would, that might help. Thanks for watching!

I can't get SD file upload working. It seems to start writing the file, but never ends. I've tried migrating to the newest bugfix release of Marlin, and that didnt help either.
@@ChrisRiley I had to make sure the enable pin was also at 3.3vdc, then have to power up the ESP8266 w/ pin0 already grounded to upload...if I tried to ground it then upload it would fail
Well at the beginning of the LOG project it was about $225 to build and I would say it was about the same print quality as an ender 3. I have since upgraded the bed,board and hotend. Log now prints almost as good as my Prusa, but the price tag has gone up a lot.
@Chris Riley when I connect my module together with my ramps 1.4 board I have a weird problem where the LCD screen I was already using will start to flicker, and then the machine will reboot and so on. The esp module blinks as though it is turning on, but for some reason, it seems like it's pulling too much current from the Aux or something. Any ideas?
@@ChrisRiley I was considering connecting the Vcc for the input of my voltage reg. To the D2+ pin on the RAMPS this way the Vin is 12v and with a 'larger' Cap across the input of the voltage reg to dampen any power fluctuations by the print head fan. I haven't worked with the RAMPS board as much as you have, do you see any problems with this idea, like potentially damaging something?

Please help me fix error!
I made it!!! Now my $2 ESP8266 is priceless.!!
I used a FTDI232 instead on an UNO. Thinking I could use the 3.3v directly. Everything went well, until I realised I still need the voltage regulator when hooking up the module to the main board.
I'm glad you got it working!
I'm using octoprint for these day to day tasks but I use a ESP8266 with esp-link firmware for over the air marlin flashing. Also the 3.3V step down converter is probably not needed. The ESP8266 can tolerate 5V
Good idea for the Marlin flashing.
@@ChrisRiley I already ditched that for the octoprint firmware flasher plugin (but it requires proper bootloader (instead avr isp method) on the printer, manual avrdude installation on the pi and much patience finding the correct settings). So overwhelming sometimes when so many different roads lead to rome.
Was literally googling this last night. You beat me to the punch! Least I have a straight forward guide on how to do it now. Thanks man!
There are a ton of good ways to get this done I found. Let me know if you find something interesting.
right chris the only thing i did not do was use the regulator but now i have the regulator its all hooked up as per your diagram im getting the same this, also the led is constantly lit on the board aswell in ur explanation you say it flases one but mine is on all the time
Those boards can vary greatly, so that might not be an issue. If you send me an email I can try to help troubleshoot it further.

Nice instruction again! The ESP is a 3.3V device, including the serial signals, while the control board is a 5V device. Wouldn't the 5V TX signal from the mainboard damage the ESP?
You don't want to run at 5v very long. That's why I created the voltage divider.
I'm using the nano. In another video said the nano reset has to be set to ground to program the esp. This works doing that, I have the 4mb esp-01s, it uploaded the CheckFlash sketch and reported config ok with 4mb flash size selected.
It seems like these all have just a few little differences.
Have everything up and running, with help of your video. Now it runs on a Infitary I3 with a custom HY_BASE_L v1.0 board, which I adapted (tricky!) to have the same AUX1 connections as the RAMPS 1.4 board. One final remark: in your video (at about 15:15) you make the final connection of the ESP8266 to the AUX1 connector of the RAMPS board. For non RAMPS users it is perhaps not clear that in this situation you connect TX(ESP) to RX(RAMPS) and RX(ESP) to TX(RAMPS). Thanks again for the video.
willemnitert Awesome, glad you got it working. Thanks for the pointer. I probably could have made that more clear.
Thank you so much!! I used an Adafruit Feather Huzzah and now my printer has WiFi connectivity thanks to your concise instructions.
You are very welcome, glad they helped you.
I've been using one of these for a couple of weeks now and although it "works" there are some big and annoying drawbacks. First being very few programs have the ability to print to a wifi-serial port (most of them expecting it to be just a serial port device) - there's only Repetier that I've managed to get too connect to it directly. And then comes the second disadvantage - there can be considerable lag over wifi which shows up as it being unable to fill your printers buffer fast enough resulting in the printer stalling while printing.
In short, if your system works such that you can upload to SD and print from there (mine doesn't for reasons I've not yet figured) then this is cheap and simple way to SLOWLY upload to SD card, but don't really expect it to replace a USB lead if your printing directly.
I totally agree, it not a very solid way to add wifi to a printer. Octoprint is still my go to.
@@ChrisRiley My Repetier Host will connect to my wifi (ESP-01s on SKR-PRO) printer via IP on my local network so I just use it that way. I use the data port 8888 and it functions just like using a USB port. I think Cura will do the same.
finally got it, it was very difficult to me to make the adapter module for my RAMPS 1.4, but finally maket and works like a charm....cheap wireless 3d printer!!!! thanks Chris!
Rodrigo Salas Awesome! Nice work! Glad it is working for you.
Hello Chris, in the schematic drawing that you sent me the RXd of the esp is connected in the D2 of ramps and the TXd in the D1, check this link, because what I was reading would be the opposite and I am in doubt to call in ramps here.
RX goes to D1 and TX goes to D0
@@ChrisRiley Thanks, but it did not work, the esp was red light on and the LCD was saying connecting and then started to give a bug in the ramps and it was restarting, I will redo everything.

Chris thanks for your help, It worked very well with WeMos D1 (ESP8266MOD) !!!!
Sweet! I have been meaning to try the D1.
@Hindo Y. It shouldn't do this if you run the data upload right after you unload the sketch. I am trying to find another work around.
@Hindo Y. Yes, upload sketch, reset, then in tools hi ESP8266 sketch data upload, then reset, log on to the ESD3d via wifi and the wizard will pop up.
I am trying to find a work around because the ESP3d instructions for the new version says you shouldn't have to do the sketch data upload, you can use the web interface, but I can't get it to work that way.
@Hindo Y. Interesting, thanks for the update.
@Hindo Y. For me it worked with the v1.0. This is how i did it:
1. Set Flash Mode: DIO
2. Set Flash Size: 1M(128K SPIFFS)
3. Set CPU Frequenzy: 160MHz
4. Erase Flash: All Flash Contents
Then i flashed the ESP3D v1.0 to the module, reset the module and then hit ESP8266 Sketch Data Upload (even though if the install instructions here:github.com/luc-github/ESP3D/wiki/Install-Instructions tell that it isn't necessary anymore). Then power off the module, remove GPIO_O to Ground jumper and power back on. Then the setup window on my laptop appeared after the wifi connection to the ESP8266 was established.
Chris Riley Thank you for this video!
Sooo...would this work with the WiFi module included with the ender 3 BIGTREETECH touchscreen? It looks like the exact same part. This video is the closest thing I’ve found to setting it up. All I’ve found is instruction videos for raspberry pi octoprint or other self contained modules. Even had to take a 50/50 shot at which way the card plugged in to back of screen.
Yes, these should work work on BTT boards and screens. It's all the same type of wifi bridge.
This is an awesome DIY! What is the bread board you're using to connect things temporarily by pushing it in. The white breadboard with the pins. What are those called where there's some connections between the pins and is good quality for continuous use like this..? Thanks!

You can, but it is SUPER slow, not sure it would be worth your time. It is possible though.
Thanks to you I managed to put the printer on wifi. Question I have how to update the marlin via wifi?
I don't know that you can, you still have to compile it. If you are using the Arduino IDE you might be able to use the IP as an upload port., but I probably wouldn't recommend it.
is the bord (Mega +WiFi R3 ATmega2560+ESP8266 (32Mb memory), USB-TTL CH340G. Compatible for Arduino Mega, NodeMCU, WeMos ESP8266) better ?

Michael, thanks for the comment and the sub. I was hoping someone else would try this out. I agree the octopi is much better, but a fun cheap project.
Chris Riley I like the esp solution as once gcode is uploaded nothing should interfere with the print. With Octoprint I have gone through periods where the usb was playing up and the printer kept micro pausing every few seconds. Octoprint also has the issue that when left plugged in my ramps board the lcd is still lit even when the printer power is off.

Thanks, I am working on that right now! Stay tuned.
Ok. for ESP3D-2.0, copy the whole tree to your projects folder, then also copy the libraries folder to your arduino libraries location. Then under examples you can load the CheckFlashConfig. Once thats ok, load the new ino project 'basicesp3d.ino'. Then download the ESP3D-WEBUI files, once you connect to the basicesp3d webpage over wireless you can upload the index.html.gz package and begin configuring the client.

Not sure what board that has, but if it has 5v ground tx rx pins available it should.
@@ChrisRiley Should have a Makerbase board? Serial pins broken out for the Makerbase TFT.
However if it ships with a TFT touchscreen controller, the serial pins are occupied. The external USB is then served by the Makerbase TFT, which is not fully command-compatible, and since USB-serial interface is implemented on board the STM32 processor, serial passthrough is not accessible externally. It is my understanding that Makerbase ships its own ESP8266-based WiFi upgrade module that goes into the TFT screen, but the firmware on the screen needs to be reconfigured or modified. Also not sure whether the WiFi functionality is actually any good.
@@SianaGearz I am not sure on the Makerbase board either, I would have to take a look at one.
@@ChrisRiley all Makerbase boards have an 8-pin keyed connector, which is laid out like this:
5V GND TX RX
5V GND NC NC
(key side here)
It's usually helpfully silkscreened on the back side of the board. It allows Makerbase TFT to connect, which is a spooler emulator with a colour touchscreen. But you should only be able to use either Makerbase TFT or any other kind of serial without interference, not both.
It's connected to the serial-USB bridge via a bunch of resistors, such as not to burn up either of the chips. If there's anything the Makerbase Gen.L doesn't lack it's the resistors - also connectors for just about anything you might think of.

It also doesn't show the IP address on boot, like you showed. I've already tried swapping the TX and RX lines, but no luck there either. Could it be that the 3.3v signal level is too low for the SKR Mini E3 (not sure what if your RAMPS board was made for accepting 3.3v logic?)?

Looks like you are missing the wifi man library. Try to use the same version as the one in the video, it's very picky about which version.
@@ChrisRiley thank you, it worked. Now my ender 3 works with Wi-Fi :D
@@ivan_23i NICE!!!!
With a 5v power supply it works, but when I connect it to a RAMPS board for power it does not, and the LCD dims.... verified it's connected right... I have a spare VR around here... if I find it I'll check that.
Mega clone have a bad habit of not having very good 5v regulators. Try plugging in the wifi to ramps then cabling the board you USB to get an additional 5v source. See if that works.

My printer is using Tiny Machines firmware, is this approach applicable?
Honestly, I have no clue how Tiny Machines would work with this,
Thanks for the detailed video!! I have had a pair of ESP8266 for forever and never really been able to use them other than issuing AT commands to it.
Anytime! Glad you found it helpful!
Hi Chris, thank you much for the good tutorial. I certainly would prefer this method over the Raspberry Pi, and I do have a few Wemos D1 Mini sitting around. The major obstacle is, however, to look for the Rx/Tx lines from my Ender 3 mainboard. Can I use the ones on the ISP socket, or do I have to look for them somewhere?
On an ANET, you would probably have to hack the LCD cable to make this work. You would need to use a lot of those PIN's. Not sure which pins they are, but it's going to be a lot of work. The performance isn't very good with these modals. I would stick with the Pi method if I were you. Maybe grab a Pi Zero W and integrate it some how.
@@ChrisRiley Thank you, Chris! Appreciated!
thank you it worked good, but i have problem connecting to the printer
when i open the web page and send some command to the printer, it didnt move or do a thing
oh and one more thing, when you hade a problem uploading the esp3d file to the ESP2866 you have to check the Erase flash to All flash contents, under Tools menu.
So, that board you're hooking the 8266 up to - does every 3D printer just happen to have that interface? I have a CR10 - without opening the control box/power supply, all I see is an external USB plug. All I really need is the ability to wirelessly upload prints, so this project will work for me
We touched on it in the stream, but all printers probably have access to this connection it's just going to be a little difficult to find the right point to plug it in on some models. Not sure on the CR10, I can take a look.
you will need to find the pinout of the controller. i dont think the cr10 is open source. contact them for the board pinouts.
Is possible to upload the firmware using this connection?
Not that I know of.
Hy Chris, i'm loving this tutorial, managed to prepare the esp, and next up is connecting it to the ramps. Would this work with a voltage divider made with resistors? Do you have a wiring diagram between ramps and esp-01?
Yes, I think a voltage divider would work just fine. I don't have a diagram, but I can probably draw one up.

Shriganesh Borse I have one of those somewhere, I will take a look.
See the ESP3D file package, there's lots of pictures containing what you need.
You should be able to just connect it straight up to USB, then make sure you select the right flash size when compiling, more or less same procedure...compile the .ino, upload, then upload the "webpage" data, then it connects with the TX/RX pins on the board...still need to wire in 5vdc and GND
Also looks like a good candidate for the wifirepeater image too

Chris, after juggling I managed to configure, but I had to do differently in some parts, change from flash mode DIO in one and then QIO to the other, CPU frequency also to 80 in one and 160 in another, then I got the same way put the SPIFFS in 1M 512K, was trial and error to set up and I did not understand why all this. Now I was in doubt on some configurations of the WEB interface, could make a small video demonstrating this, for beginners as I is something crucial, for example IP is set as static, this is or would be DHCP, printer settings, etc ... I apologize if I bothered you with so many questions, I have a lot to thank and I have learned from you it is difficult for a beginner and with the language barrier it gets more complicated. Thanks
Things change so fast with these things it's to keep up. I am glad you are making progress.
Chris, one last request, I did not understand the connection scheme of ESP with AMS in ramps, even for what I downloaded in your google docs, could you send me this link? In its drawing the 5V of the ramps Aux1 goes on the VIN of the AMS, GND AUX on the AMS 2 and the GND of the Esp (that is not GND is out) and the AMS 3 that is GND goes in the VCC of the Esp, I was confused with these connections.

Great, thanks for watching!
Hello, Nice video!!
I'm using the same version that you are using. But when I'm going to the Dashboard, I cant send any commands to my printer.
Do I need to change something in Merlin?
Could you send me the merlin file that you are using?
That has been so long ago I don't know where that config is. If you are using Marlin 1.1.x then you don't have to change anything. If you are using 2.x then you have to add the second serial port in configuration.h
@@ChrisRiley I'm using the 1.1.x merlin version....The serial port is set as "#define SERIAL_PORT 0"

@@ChrisRiley yes, but I followed another tutorial, my module needed another flash before this firmware. It is a Chinese tool, called ESP8266_Flasher_Tool, now it works nice.
Thanks for your video, you made me put this on my printer. Works nicely!
Hi Chris great video. Thank you for everything you doing. Can this be used on a Trigorilla V1.1 board ( on Anycubic I3 mega). I checked and on the board I have 4 pins available GND , 5V , TX3 and RX3 ( and UART next to them). Also do I need to install Marlin or it will work with the official firmware? I tried the OctoPi variant on a Pi4 4GB but I have problems with my prints and think the reason is a bad communication between Pi and printer. Same G code from SD card came out perfect but from OctoPi I had a lot of strings , bad retraction and miss steps. The only reason I try this is because the main thing I need is to have remote access to monitor the printer ( mostly temps ).
For monitoring this might work for you, not so much on printing really. It should work on that board, I don't think you will have to change the firmware, they use a version of Marlin, just not sure which one.
Fantastic video! One question though: In the ESP3D Github repository, under Install Instructions there is an EDIT that says that the SPIFFS Tool is no longer necessary because since FW version 0.9.99 there is a self uploader. So that means that when I have everything ready and upload the FW (1.0) into my ESP8266 the sketch data will be automatically uploaded with the FW? Can I completely skip the SPIFFS part of your video?
Well, it says that is will work with the self uploader, but I can't get it to work. The only way I can get it to successfully upload is by loading the data first. Give it a try, but I have had no success.
Can we connect WiFi 3d printing with raspberry pi (octoprint) without using USB port..
You could use GPIO pins on the pi if you new the right pins on your mainboard, but that's about the only thing I know. Is there a reason you can't use USB?
Excelent!!!! You are cool !!! Is it possible to connect it to SKR E3 DIP ?
Yep, that should be the same type of software they use on the SKR1.4.
Hello Chris Riley
. I loved this video but I have a question. Need I connect twice 3.3V at ESP8266?
Yes, one of those pins will have to be pulled high.
@@ChrisRiley Thanks!!!!
Hi Chris thanks for the aweasome tutorial. I just have one question I went to the Github wiki for ESP3D and they add a couple of resistor CH_PD and RX pins they also conect RF to ground on the ESP8266. Is it needed or with your setup I fine?
It depends on what ESP module you have, it seems they are all different. It's kind of trial and error.
Chris Riley thanks man!
i order a esp8266-12e waiting to ship from china, it got a build in AMS1117 voltage regulator and use a 5v usb phone charger to power up the esp, so do i need to connect esp 12e the gnd to ramps 1.4?
Yes, I would just to make sure they are both consistent.
so if the RAMPs had 3.3v pins, could the ESP cip have been plugged directly into Aux1?
It would kind of work. The current isn't high enough. It would probably work when you were configuring it, then fail when trying to connect to the wifi.
What series firmware marlin in arduino?
Not sure what you are asking?
@@ChrisRiley saya tidak menggunakan lcd dan kartu memori...apakah hal ini mempengaruhi saat uploud di komputer?
So geat, Does the printer work when the computer is turned off? Or always have a PC connected to Wifi
It will be standalone after you get the file uploaded.
13:00 - All works fine for me up to this point, at which it never connects to my wifi. Module gives 10 flashes of the blue led, then nothing.
Hmmmm, the ground is off of GPIO0 correct?
Yeah, the issue is only when I reboot to connect to a AP. Using the module in captive portal mode works fine, everything seems to be configured correctly (although the password is shown as the wrong number of "*"'s), just once I've done that, I power down and reboot.. and ....nothing seems to happen other than a few flashes of the WiFi led.
Also, its supposed to be reset-able by grounding GPIO2 during boot to reset the eeprom setting - that's not working for me either, so I'm starting to think the software is more buggy than it should be.
It could be the software for sure. I haven't tried it in a while. I will give it another try and report back.
So i saw that I have a wifi port on the board for the LD-002H.... lets see if we can get some wifi on there :) thanks brother Chris !

iv got it hooked up properly but it generates an error now when flashing
I am still not sure what is going on here. I can't reproduce this error.
@@ChrisRiley well mate its all wired up properly and i get same error another guy on here is having same issue
Just a question, other than being mostly DIY, how does this differ from the Raspberry Pi - OctoPrint method? To me, they seem to be the same concept.
They are pretty much the same concept, but Octoprint is going to be much faster and have a lot more plugins/features for it. The ESP option is a lot cheaper than the Pi, but not as fancy.
Hi Chris,
great video and a whole bunch of information.
In your video it looks like being so easy to conect the ESP to AUX1. Did you change anything in Marlin?
I tried to conect my NodeMCU ESP12 to my anycubic Kossel having a Trigorilla board. This board has an UART3 port using D15 as RX3 and D14 as TX3. Ground and 5 V is workig to drive the NoedMCU, but I can't get the data lines working. I tried to use Serial_port 0 to 4 in Marlin 1.1.8 but with no help. Do you have any clue?
Many thanks and dear greetings
Simone
I didn't have to change anything in Marlin to get the Wifi to work. As long as those pins don't interfere with other serial traffic you should be fine. In the PINS.h file you might try swapping out the pin numbers to use the same pins as AUX1 normally would, that might help. Thanks for watching!
