FYSECT e4 ESP3D TMC2209 UART driver error

[yoroboticscolombia]

Hi, I have a fysect board, but I upload Marlin without esp3d support enabled, the connection works good, however if I enable esp3d support I get driver error, Im not sure if its related to esp3d, please guide me.

18:58:52.344 : E (5870) uart: uart_get_buffered_data_len(1342): uart driver error

what can be causing this. I have already knowledge of marlin and esp3d.

ESP3D Firmware:

ESP3D FW version: [3.0] ESP3D-WebUI Version:[3.0] Wifi mode:STA] Flash method: PlatformIO

Name: [Marlin] Version [bugfix-2.1.x] Board used

MCU:[e.g. ESP32] Name:[e.g. fysect e4] Flash size: [16M]

thanks.

Thank your for submiting, please be sure you followed template or your issue may be dismissed. if you deleted the template it is here

ESP3D is not supposed to be used with FYSECT e4, Marlin mainstream use ESP3DLib V1 so I do not understand your configuration

The TMC Uart configuration is not easy - did you tried standalone configuration ?

Also please try Marlin latest release version also - not bug fix

[yoroboticscolombia]

ESP3DLib V1

Thank you so much, yes Im trying yo use it with marlin, can you tell me wich is the best marlin file to use, now Im confused with the repositories, since some wont compile with visual studio,

Thanks.

[luc-github]

what issue did you get with released version of Marlin ?

[yoroboticscolombia]

it happens, that the fysect has the tmc2209, with uart, so its not possible to change the current, when enable esp3d support in advanced.h, i get this:

uart: uart_get_buffered_data_len(1342): uart driver error

when I disable the esp3d, the connection to the driver is ok,

do you think its something related to the serial that handles the steppers with the esp3d?

[luc-github]

yes the configuration may be incorrect because esp3dlib does not use any uart, it use fake serial but use SERIAL_PORT_2 - so you may wrongly configure SERIAL_PORT_2 as the one used by TMCDrivers also I am not expert sorry for TMC drivers

[yoroboticscolombia]

thanks, that clarify more for me, but esp3d does not connect to marlin if I dont enable serial port 1, in configuration.h,

[luc-github]

did you checked how FYSETC configure the board ? https://github.com/FYSETC/FYSETC-E4/tree/main/firmware/Marlin/Marlin

[yoroboticscolombia]

Thanks, Yes, its the same, however that marlin does not compile, it has a lot of errors in visual, but the pinout is the same, it looks that something is conflicting, if I disable tmc driver, it works, but the motors get too hot, but the marlin in the fystect repository has all features,

Is there any way to change the esp3d baud rate for the fake serial port? because i see the baud of the tmc is 115200, but the baud rate of teh esp3d is 250.000, may be thats something to do.

[luc-github]

esp3d does not use real serial change Marlin serial baudrate to change baudrate

[yoroboticscolombia]

Thanks, I tried somehow the tmc are making the esp32 to fail, can you tell me for the esp32 of fysetc e4, which is the best firmware using esp3d, thanks.

[luc-github]

should be latest release of Marlin , bugfix is not supposed to be stable but test version because it is Marlin configuration issue, did you asked on Marlin discord ?

[yoroboticscolombia]

Yes, and they closed it, since said I have to search my own, Im still trying to compile the firmware that was uploaded by fysetc, but it looks like it was compiled in ubuntu, its kind of frustrating,

[luc-github]

I used the latest Marlin release https://github.com/MarlinFirmware/Marlin/releases/tag/2.1.2.1 configured board same as https://github.com/FYSETC/FYSETC-E4/tree/main/firmware/Marlin/Marlin for board, SD and TMC drivers (there are several settings to change) applied the patch I suggested here to pass the compilation issue : https://github.com/MarlinFirmware/Marlin/pull/25743#issuecomment-1546596416

So your issue is definitly your configuration settings

[yoroboticscolombia]

Thank you so much for your guidance, I was able to flash the board, couple changes I had to make is that I changed the esp32 module from the board, so it kept resetting, so I put board_build.partitions = huge_app.csv board_build.f_flash = 40000000L, and it worked, good, tmc connection good, and esp3d portal working, however usb works good, but the control from the esp3d webui, it does not do nothing, and it cannot open the printer settings, can you check if this happen to you too,

what could be causing it,

[luc-github]

you did not configured ESP3D in Marlin : https://esp3d.io/esp3dlib/v1.x/installation/index.html

I did not changed anything in platformio.ini because it is correct - I do not understand why you had to change the values you mentionned :

[yoroboticscolombia]

Hello, after many attempts, I finally got it flashed, Thank you so much, its a shame the esp3d v3 version is not yet implemented in marlin, since de current one sometimes crashes, along with the serial port freezes the printer if the usb is being used, however if you have some to test, Id like to do it, since the board, is very powerful,

I made the changes because I desoldered the current chip, and replaced it with a 16MB flash chip.

[luc-github]

I made the changes because I desoldered the current chip, and replaced it with a 16MB flash chip.

why did you do that ? The E4 is already a 16MB flash ESP32

[yoroboticscolombia]

The board I received, had a 4MB chip,

[luc-github]

The E4 ? you should return it

So your serial issue may be an hardware issue also

[yoroboticscolombia]

I bought it like 6 months ago, so I was testing until now, thats why. But why marlin has not made the changes to the original repository? so It can be build, I saw in your repository marlin with esp3d v3, thats the one I tested at the beggining, but I got the serial messages,

[luc-github]

Hmm current version of Marlin already have 16MB for E4: https://github.com/MarlinFirmware/Marlin/blob/bugfix-2.1.x/ini/esp32.ini#L29 not sure to understand your meaning

ESP3D 3.0 is not yet ready to be released so I did not pushed to Marlin yet, it is usable for sure but I did not tested all config yet

[yoroboticscolombia]

you have this in your marlin repository, https://github.com/luc-github/Marlin/tree/ESP3DLib-V3-2.1.2 https://github.com/luc-github/Marlin/tree/ESP3DLib-V3-bugfix-2.1.x

[luc-github]

yes that my fork - I modified them to test ESP3Dlib v3 because it use different platformio/arduino core than current one so it also affect Marlin code, so I had to modify some part of Marlin

[luc-github]

I close issue - I managed to fix my fork of Marlin for ESP3DLib 3.0 to make it work : Here the config files for the bugfix-2.1.x https://github.com/luc-github/MarlinConfigurations/tree/bugfix-2.1.x/config/examples/FYSETC/E4

And my fork based on latest bugfix-2.1.x : https://github.com/luc-github/Marlin/tree/ESP3DLib-V3-bugfix-2.1.x

[yoroboticscolombia]

Thank you so much, I tested in the fystect board, and it works very well, the only thing is that the sd files are not listed, is sd printing not supported in the v3 version? sd support is enabled and the files are listed with the m20 command, but they dont show in the panel, do you need to open a new issue?

Thanks, good job.

[luc-github]

SD is working on my side :

Check the setting for the sd speed factor

And yes please open new issue with all informations of webui version and sd card caracteristics

[yoroboticscolombia]

Thank you, I changed that already and the sd card was recognised, but not all files are shown, if I choose sd, no more than 15 files are shown, but if i choose extra sd, all files come
