[BUG] Typo in esp3dlibconfig.h - MARLIN_PATH

[sargonphin]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

There is a typo in the relative path at line 45 of the file esp3dlibconfig.h:

#include MARLIN_PATH(inc/MarlinConfigPre.h)

This returns a file not found error:

.pio\libdeps\STM32H723ZE_btt\ESP3DLib\src\esp3dlibconfig.h:45:54: fatal error: C:/Users/x/OneDrive/3D/inc/MarlinConfigPre.h: No such file or directory

After correcting the line I now get this and I am stuck there:

#include MARLIN_PATH(Marlin/src/inc/MarlinConfigPre.h)

.pio\libdeps\STM32H723ZE_btt\ESP3DLib\src\esp3dlibconfig.h:45:54: fatal error: C:/Users/x/OneDrive/3D/Marlin/src/inc/MarlinConfigPre.h: No such file or directory

The folder "3D" is supposed to be "3D PRINTING". It was my mistake though, I usually never put spaces in folder names for that exact reason. But I don't know how to fix that. No, renaming the folder is ABSOLUTELY NOT an option! XD This would break a considerable amount of already-configured paths for many other projects

Also as you can see I am using a BTT Octopus MAX EZ with the STM32H723ZE MCU. I am currently trying to configure the Wifi add-on board ESP32U-WROOM that I bought ages ago

BTT Octopus MAX EZ with the STM32H723ZE MCU. I am currently trying to configure the Wifi add-on board ESP32U-WROOM that I bought ages ago

This board is not an ESP32-based board. You simply enable the correct serial port for the WiFi addon module and not WIFISUPPORT/ ESP3D_WIFISUPPORT.

So what's the deal with this adapter here:

https://www.amazon.de/-/en/gp/product/B0B5ZWT3JP

It's supposed to be compatible with the board I have. Is it just not supported by Marlin at all? I can see its Wifi hotspot when I slot it into the board and such but no way to use it with Marlin so far

I think something was not clear from the begining. My board has Wifi support as an add-in card, and has the following section in its pins, from file Marlin\src\pins\stm32h7\pins_BTT_OCTOPUS_MAX_EZ.h:

But it requires WIFISUPPORT to be enabled. This is where I am confused regarding the Wifi add-in card, because if I enable this, it complains about the initial problem I have encountered earlier.

So should this section in the pins file be removed? Or is something different expected in this port?

[EvilGremlin]

These pins are not used. There was intention to untie WIFISUPPORT from platform and apply it to modules too (for potential GPIO functions) but changes weren't completed.

[thisiskeithb]

Those ESP wifi addons need to be flashed using a programmer like the BTT Writer with firmware like ESP3D. Then you enable the proper serial port in Marlin and that's it. They communicate over serial.

While some non-ESP32 boards have WIFISUPPORT code blocks in them, they do not apply here.

Okay super thanks! :) this is helpful
