Hey Chuck, glad you were able to work through it. Yes, a lot of these boards put everything on the same serial bus so things collide. I have never been able to make Marlin work with the USB serial connection, Wifi and TFT all at once. Good to know board_build, that means the marlin team has corrected somethings. That will make it easier.

LOL, thanks! Others have said that, I think maybe the programmer I have might not be 100%.

Thanks David, yeah Octoprint is just awesome, that's all there is to it.

@@ChrisRiley So with running Octoprint on a 4B its pointless putting WIFI on the SKR 1.4T?

@@lookin4ward1 Pretty much, it is not substitute for Octoprint.

Always a great tip.

Glad it was helpful! Thank you!

Yeah, it was a fun little side project at least.

Thanks! That's good to hear, hopefully it is just the BTT writer causing me problems.

i am using an FTDI aswell but i do not have the file system image upload option at all...

Awesome, glad this video was helpful.

Great to hear, happy to help!

Chris is the best. His videos are worth watching all minutes, not any single second is wasted.

Thanks! Great to hear! I really like the software.

Hey Eric, I am going to give that one another try with the newest ESP3D version.

@@ChrisRiley I think Luc has some specific closed source code for Panucatt to work with direct SD access. So loading the latest open source version might break the high speed SD access. Maybe double check with him first.

@@eclsnowman Thanks, will do!

You're welcome, give it a try, good luck!

I might have mixed that up a bit.

Thanks for the comment Alex.

Awesome, great combo, I might have to try it.

Thanks for sharing!

Thanks Charles and thanks for the extra info!

Good to hear, thanks!

Check under env:esp01s.

@@ChrisRileygot the same proble, what you mean with it?

@@Thermal488 There is an option in the menu for the ESP01, you can upload from there.

Nice, yes, there are a lot more of these boards supporting other wifi modules now. Great to see.

Cool, yep, I use to have one on my RAMPS.

Cool idea.

Awesome setup! I don't know what app they use. I would guess there is something you could use. How do you control it while offline, with a screen of some sort?

@@ChrisRiley I use the MKSLaser app on my phone to launch the cut from the internal card file. But maybe this isn't really "offline" since there is the connection to my phone via wifi during the cut (still more reliable than the laptop connection). And I have experienced the machine going wonky when I approached the table with my phone in hand to observe the cutting process. This usually results in me quickly finding the cord to unplug everything. LOL Since the table is just resting above the work if it takes off in some direction it can get moved around - both good and bad I suppose. So far nothing major happened before I got to the plug. I'm going to buy some faraday fabrick and make a sleve for the plasma lead. I'm also waiting for the delivery of some sheilded twisted pair wire. I'm then going to see if Grbl Controller app can connect to the board since it has z-axis control. Just have to wait for the OTG to C-type adapter to arrive. Peace.

Thanks Travis!

Thanks, that's funny, I know that tip and I always still do control pannel out of habit I guess.

Same here :(

The library may have changed. You can try using the web tool ESP3D software gives you or try running a clean from the build menu to reload the libraries.

@@ChrisRiley used web ui to upload data files. Works like a charm. Thanks for your videos!

Great to hear!

Thanks, Yes, I plan on doing a video on this.

👍

It's kind of a fun project.

Great to hear, the Marlin team has changed somethings up for us to make this a little easier.

Thanks Jerry!

I have no clue how long it would last. There are tons of different types of these out there as well.

To the best of my knowledge, it will smoke immediately. If they were using one of the dev modules (two rows, about 30 pins) they usually have an AMS1117 voltage regulator. It will take the 5v USB, and make it 3.3v for the ESP8266. The AMS1117 can technically go up to 12v, but only for a short time. The ESP-01 that he's using doesn't have the onboard voltage regulator. It only has the ESP8266EX , T25S80 serial chip, power LED, and a few passive components. These are made to be dirt cheap, and they offload everything, like power management, to the host machine.

Thanks! You have already done all the things I would do. I have heard a lot of others with this same issue. I am not sure what causes it I am afraid.

@@ChrisRiley thanks any way al hope is not lost yet will keep on bugging every one until i get told to get lost or something . :-)

I don't know of a way to do that. With apps like pronterface you can type an IP address over the com port.www.pronterface.com/

Awesome, great to hear they updated it, I am going to try it out.

Hi, perfect for me but, my TFT24-v1.1, don´t work. If you put its #define SERIAL_PORT 0 all is correct, TFT and WIFI ok. I´m in MARLIN 2.0.6.1 #define SERIAL_PORT 0 // Port for REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER (TFT 24 V1.1) /** * Select a secondary serial port on the board to use for communication with the host. * :[-1, 0, 1, 2, 3, 4, 5, 6, 7] */ #define SERIAL_PORT_2 3 // Port for WIFI ESP3d esp8266-01 #define LPC_PINCFG_UART3_P4_28 Important!! on the ESP8266 you have to solder a wire between 3.3v and CH-PD , the pins on the SKR board are "not used" Chris, good video and very clear, Now I am subscribed and you have my Like... Mathias THANK YOU for your idea, I have been changing options a week before. Greetings from Spain...

Thank you so much 😀

The moved them into their on ENV, check out the ones below, they are labeled esp-01.

🙂 I'm glad you got it going. Thanks for watching

@@ChrisRiley do i have to use a sd card to do that. Because i broke my usb input. And sd card input is getting worse too

@@ChrisRiley can this work without a sd card?

If you ahve a 1.4 you might need the ch340 driver installed on your computer. Check device manager to see if the board is there in com ports.

I haven't seen that yet, I'll take a look.

There might be a problem with the voltage regulator on the board. Does it check out with your multimeter?

I had exactly the same issue. I solved this problem with this: 1. Update the Espressif 8266 Platform to 2.6.2 (PIO HOME) --> search for "8266" / click the Version (right Corner) / update to 2.6.2 / restart VS Code 2. open the project and edit the "platformio.ini". Add line " board_build.filesystem = littlefs ; SPIFFS ; " in the [env:esp8266] segment . Alternativly copy and paste : [env:esp8266] ;esp8266 core 2.5.2 platform = espressif8266@2.6.2 platform_packages = toolchain-xtensa@2.40802.200502 board = esp01_1m board_build.filesystem = littlefs ; SPIFFS ; framework = arduino monitor_speed = 115200 ; set frequency to 160MHz board_build.f_cpu = 8000000L ; set frequency to 40MHz board_build.f_flash = 40000000L board_build.flash_mode = dio upload_resetmethod = nodemcu board_build.ldscript= eagle.flash.1m256.ld build_flags = ; -Wl,-T -D PIO_FRAMEWORK_ARDUINO_LWIP2_LOW_MEMORY -DNONOSDK221=1 -DNDEBUG -DVTABLES_IN_FLASH upload_speed = 115200 lib_ignore = AsyncTCP ESP32NetBIOS ESP32SSPD 3. "Build All and/or UPload All " under the Project Tasks / General. NO separate Donwloading for Ffilesystem required. After that, The ESP3 Accespoint appeared and was able to accept thef iles in the data folder. 4. Continue like Chris suggested I recently got erros for compiling the code. But I just hit the Build/ Upload button again and everything was fine . Please note the filesystem is not SPIFFS Chris has used. But LittleFS is the one that is preferred for ESP's with limited memory in the future. see : diyprojects.io/esp8266-upload-data-folder-spiffs-littlefs-platformio/#.X41Ji9AzZEZ regards TOM

Thanks for the assist!

You welcome

@@tomsakelby9314 If it helps someone else, I had to restart VS Code twice for the settings to show up in order to upload through: Project Tasks->Default->env:esp8266->Platform->Upload Filesystem Image

Try a few different serial ports, they may be different on your board.

Good luck with your project!

Thanks! No, Octoprint just serves serial data, just like an SD card would. No help on the compute side. If you want a setup like that you would have to run something like Klipper firmware.

Octoprint needs python, so using something that runs linux is your best bet.

Yeah, the best install for the MK3 is Octoprint.

I have done one, but they are mainly just to use REPRAP firmware. kzfaq.info/get/bejne/rdaKpJWQ06qUeKM.html

For some reason, our channel got a bunch of comments recently that are over a year old. I hope you got your issue solved. We didn't purposely ignore you. Thanks for watching!

Did you try changing up the reset method?

By all rights, you should be able to, but I have never tried it. Yes, I would give the TFT slot a try as well.

@@ChrisRiley Thank you Chris. I ll give a try.

If you don't need to use the serial cable (USB), set your second serial to 0.

I'm glad it worked!

Those should be active all the time, so there might be something wrong with the board or voltage regulator.

​@@ChrisRiley I just buyed two of the same SKR 1.4 boards and both have the same issue, and specifically to use with the esp8266 01, the only difference with the video is that you used the SKR 1.4 TURBO, but seeing the pinout of the WIFI port on skr1.4 and skr1.4 turbo on the board is just the same, THANKS for the response!!! I will try to solve this from the hardware side make a litle piece of board to make a short between 3.3v pin and CH_PD. Your videos are really helpfull and usefull. Keep going man!!! my best regard from Paraguay SOUTH-AMERICA

Correct, it will just be a serial bridge at that point. The SKR 1.4 has a virtual to allow the USB port to work.

Ah, great info, that makes since.

Make sure serial 0 is set to -1 serial 2 needs to be 2 I think, by try a couple of different numbers. Also, if you have a touch screen, that might be interfering.

@@ChrisRiley I do have a touch screen (TFT35). How would that be interfering?

@@ADBBuild They run on the same bus, so you might be bit bashing, the serial info collides. Try one or the other to rule it out.

No ethernet yet that I know of.

@@ChrisRiley seems like marlin does support teensy 4.1 ethernet

Thanks! I need to find a good auto off module, I would like to try that setup.

SKR+Raspie == just use klipper ?

I haven't really talked much about building it. It's a copy of Tom's Dolly build. He has a lot of videos on his.

No, you shouldn't need to use it.

@@ChrisRiley Thanks! I have a couple of clones from aliexpress.

I figured this out because when I opened the framework HardwareSerial.h it had the changes already made but said "#if defined(LPC_PINCFG_UART3_P4_28)" and I couldn't find a define for it anywhere. But once I added it my esp8266 would then connect to the printer. Without, it would not.

Cool, thanks!

You're welcome! Thanks for watching

I have one form BTT as well and I was able to write to it. The IO0 is the pin that makes it writable. ESPflashtool should work for you. Make sure you have the TX and RX pins flipped.

@@ChrisRiley thx Chris for the video and for taking time to respond, i will try another PC then, maybe some problem with the COM communication alltogether, i have even (after checking it muuuuultipletimes) tried to purposely switch tx/rx and that didnt help either, so i dont think its connection problem, i will follow up when i have time to test with other machine, so maybe other users in the future will have a reference how to fix such issue :)

The 8266 board you mean?

Wow, not sure on that, if the serial was setup wrong I would think it wouldn't work at all. There are some jumper setting on that board, maybe check over those again.

@@ChrisRiley I got it working later the day I still don't know why ... I changed no settings at all but went from the uart pins on the wifi place to the TFT pins and it just worked

It looks like it didn't get the library installed. I would try to reinstall the platformio extension and see if that helps. Also, you might try running a clean from the build menu.

Thanks!

Thanks for watching!

I'm not sure, but I will be looking at a new GEN L board sometime soon.

Everyone of those boards is a bit different. What ESP and what writer are you using?

@@ChrisRiley the writer is the sAME O9N IN THE ARTICLE V1.0

I don't currently, but I might run through it in the future.

Thanks! It's really hard to tell, they read 100k at 22c I think. To be able to tell what thermistor you have you would have to plot it out with a thermal couple.

I can't get serial to work on those chips at all. I am not sure why really.

Hmm, that doesn't even look like the right file extension. I would delete your ESP3d folder and start over with a fresh unzip.

@@ChrisRiley i finally did it but i couldn't find the ESP3D wifi on my network , how can i connect to it ?

Thanks for the link! They indexes are always helpful.

I am not sure what to check, did they release a new version?

What could we do with no printer?

Wow, thanks!

I did a search in the code and can't find where that is set. Jump over to their discord, they should be able to help you.

You will not be able to use the screen and the wifi connected to the board the serial gets confused. That's why it works on the screen, the screen is utilizing one of the serial ports. It's unfortunate, but you will have to pick and chose with serial devices you have.

@@ChrisRiley Chris, good day.I watch your videos many times .You have shown the solution path in Marlin 2.05,I use 2.06, and in the file (HardwareSerial) uart3 looks like this - (( } else if (UARTx == LPC_UART3) { // Initialize UART3 pin connect PinCfg.OpenDrain = 0; PinCfg.Pinmode = 0; #if defined(LPC_PINCFG_UART3_P4_28) PinCfg.Funcnum = 3; PinCfg.Portnum = 4; PinCfg.Pinnum = 28; PINSEL_ConfigPin(&PinCfg); PinCfg.Pinnum = 29; PINSEL_ConfigPin(&PinCfg); #elif defined(LPC_PINCFG_UART3_P0_25) PinCfg.Funcnum = 3; PinCfg.Portnum = 0; PinCfg.Pinnum = 25; PINSEL_ConfigPin(&PinCfg); PinCfg.Pinnum = 26; PINSEL_ConfigPin(&PinCfg); #else PinCfg.Funcnum = 2; PinCfg.Portnum = 0; PinCfg.Pinnum = 0; PINSEL_ConfigPin(&PinCfg); PinCfg.Pinnum = 1; PINSEL_ConfigPin(&PinCfg); #endif )) I Can't connect WiFi on the Board(TFT is disabled).Help if you can.Thanks.Stability and good luck!

@@jress6778 Is the module powering up?

@@ChrisRiley Yes, the module works clearly on the screen.If I put it on a Board without TFT, it is not determined by the Board.The port is registered 3 and 0. the code in Marlin is not clearly spelled out;in the letter above.Thanks.Good luck!

Same problem

You are welcome!

Glad it helped, thanks

If they don't have a pinout, use your multimeter to find the voltage pin.

@@ChrisRiley how will it help me to control the board with WiFi?

Thanks for the info!

I have seen that workaround before, seems to work pretty well.

Thanks! I did, I still can't get it to upload, it throw a can't connect error.

Since there are only 2 serials you can talk to, you are going to have to pick with two you want to use. serial 0 serial 2 3 is wifi module and screen. serial -1 and serial 2 3 is USB connection and wifi module.

I worked on this for hours trying to figure out why it wouldn't reset. It's something in the ESPtool.py scripts. All the other tools worked just fine with the ck setting, but not the esptool. If you leave it set to ck it does a soft reset before the flash and a hard reset after. That wasn't enough to get the writer to work. I set it to nodemcu to issue a default reset before the flash. That seemed to do the trick. Again, all other tools worked fin with the ck option. Not really sure what part was wrong, the tool options or my writer wasn't working correctly.

@@ChrisRiley Diligent as usual! I just attempted to look at the trail from the "Upload file system image" task menu item through to twiddling of the RTS line, and there are so many places where something could be amiss. And it's very easy for this to turn into a multi-hour rabbit chase, as you note. Because platformio makes things so simple :-). Not the least problem is that all the software libraries along the way have to understand which polarity of the RTS line means what, and when it can and should be changed. Does setRTS(True) mean set it low, or set it high? So all participants, from the CH340 (or FTDI) chip, Writer board designer, CH340 driver, Windows serial port API, PySerial and esptool.py have to agree on how this is supposed to work. Not to mention drivers for other platforms. I now see there's a long history of rampant mess in this area, judging by github.com/pyserial/pyserial/issues/124. On top of some models of ESP apparently misbehaving if the reset line is held on too long, or not long enough, or.... OK, I think for now I'm just going to offer sympathy :-).

@@Graham_Wideman LOL, sympathy is very welcome! Not sure if the RTS gets toggled high or low, that might be a good test to see what happens.

Hi. Use the connections from the previous video. Thank you very much

Yes, the first video should help you.

I can check it out, not sure how it works yet.

@@ChrisRiley Me neither. Been banging my head against a brick wall with it. But other than processing power there's not a lot of reason the pi shouldn't be able to run platformio to flash the board via serial. Even building the firmware on something more powerful like a home pc and sending it to the pi over ssh to then flash. Anyhoo, I love the content bud keep it up :)

Cool, thanks for your insight!

also, @17:01, I dont have the "Upload File System" button.....

Check the ESP01 env, it should be there.

@@ChrisRiley So, the files are in esp3d/data (had more time to actually comb through everything). It appears as though you can still interface with the it through the web, you just need to manually upload the index.html.gz there. A button up top will say "switch to ESP3d Interface" or something similar, that will initiate the wizard. Great Vid, and Thanks for the help!!

In VScode? Do you have the other options.

That's a good question, I am not sure how that would work.

I doubt it, but Octoprint does!

pleaseee, im having issues and can't get it right, can I get in connection with you somehow? Thanks

Cool, looks like others would like a video.

Not on the 1.4, but I have had on the SKR2. kzfaq.info/get/bejne/rdaKpJWQ06qUeKM.html Not sure that 1.4 will support RRF.

There should be a ENV:ESP01 in there now to load the file system.

@@ChrisRiley -thanks, does this replace the [env:esp8266]?

No, just for writing the file system, not for code flashing.

@@ChrisRiley - So where would I need to add this ENV:ESP01?
