Smart filament sensor not working when connected to TFT35 E3 V3.0 in touch mode

[killrob]

hi, i have connected the smart filament sensor to the TFT35 E3 V3.0 at the fil-det connector on TFT, this is the part in config.ini fil_runout:2 fil_runout_inverting:1 fil_noise_threshold:100 fil_runout_distance:4 i suppressed all lines comments.

I had done a 5.30 hours print and at 64% the filament ends, what i expect is that the print pause and the LCD tells me that filament was runned out, but no message and no pause from the LCD, with the result that i have a couple of layers missing in the print.

bump. Did you ever figure this out? I have the same TFT with an SKR 2.0 rev B and can't get the BTT Smart Filament Runout Sensor to work.

@mlauber i solved attaching the SFS directly to monitor not to motherboard. But you have to change the config.ini of the monitor like this: fil_runout:2 fil_runout_inverting:1 fil_noise_threshold:100 fil_runout_distance:7

and disable the LIN_ADVANCE in marlin's Configuration_adv.h and enable M114_DETAIL in the same file

How do you do that? SFS 2.0 has wire on 4 pins from one side and 2x2 pins from the other (one for the move sensor and one for the switch sensor). In TFT35 E3 V3.0, FIL-DET sensor has only 3 pins.
