SKR-2 with TFT43: sometimes a "no printer detected" in touchscreen mode

[mslucass]

I have a SKR-2 with the TFT43 v3.0 with Marlin.

In Marlin mode I can print in touchscreen mode I can sometimes print.
After several prints in touchscreen mode I will get the no printer detected error. But even if the touchscreen mode does give this error the Marlin mode does work and is able to print.

Where do I have to start looking?

#define SERIAL_PORT 1
Baudrate 115200
#define SERIAL_PORT_2 -1
#define SERIAL_PORT_3 3

I have attached my complete marlin configuration
MarlinConfig.zip

I found the error... a bad connection in the TFT cable... Sorry
