You can't remap FAN0 to some random port. you can only remap it to the port that switches the Mosfet transistor. This port should also be capable of PWM regulation....

Try a few different SD cards.

You can find the pin specification in the datasheet for the processor. Your board was manufactured with several types of processor.

In that case, you can swap the wires on the motor connector.

You could use a TTL-USB converter and connect it from the TFT connector. Then you would have a printer available via a USB connector.

You must compile Marlin with serial port 2 enabled for example: #define SERIAL_PORT 2 the speed must be the same in Marlin and TFT for example 115200 #define BAUDRATE 115200...

The serial port number depends on the Marlin motherboard used and the pins used.... This is not a lottery :-) For SKR PRO V1.2, serial port 1 is on the...

The TMC connection error is displayed if you power the board from USB, or if you do not have the TMC drivers configured on the UART mod
