Did you check the voltage output and the polarity on the fan? You could try to invert the Gnd/V+ pin from the fan and check if it's the issue.

Will be dangerous if the probe does not output 5v or less when he trigger... The sensor port is intended to be protected with a optocoupler, just sad is not...

@pilgerone can you try to remove the .vscode folder and start again your VS Code? Normally they should not include the .vscode folder into the repository :/

Did you compiled the enviroment version that end with "btt_USB" ?

Which TFT are you using, the TFT35? there so many at BTT... Could be the issue is with Klipper: https://github.com/Klipper3d/klipper/issues/2546

Thanks for your research and advice @westhedge

Same for me, I've buy the BTT ESP32U and there's no documentation on how to install it.

Hi @lukasloetkolben could you describe all the step needed to compile and flash it ? I've already buy the BTT Writer but I must look how I can connect it...

@zvonka what issue did you get with Marlin? I've moved from the BTT 2.0.9 to the official marlin bugfix and got no issue. Just needed to merge my previous config...

@penke78 do you still have the error? What's the latest modification, on the printer, before you got the error? Could you provide the full error message ?
