SKR2 & BTT_TFT35 v3.0 E3


Recommended Posts

I recently purchased a BTT SKR 2 getting Marlin installed and mostly working, but I can not get the BTT TFT that was ordered as a Bundle to work in the BTT TFT mode. it works ok in the "Marlin" mode, but for the life of me I can not get the TFT side to work.

I have set in my Configuration.h;
 

#define SERIAL_PORT -1 //have tried 0,1,2

#define BAUDRATE 115200 

#define SERIAL_PORT_2 1 // have tried 0,1, 2
#define SERIAL_PORT_3 3 // Have tried 0, 1 and -1



and set;
#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER  //enabled for LCD12864

what is the magic combination for this, is there additional conf files needed?  I'm at my wits end!

"1. Please make sure that serial port 1 is enabled in the marlin firmware

#define SERIAL_PORT 1

, and the baud rate is set to 115200


2. Please confirm that the wiring between the motherboard and the touch screen corresponds to
   Motherboard Touch Screen
    5V<->5V
    GND<->GND
    TX<->RX
    RX<->TX
    RST<->RST

3. Make sure the baud rate of the touch screen is also 115200"

Where did you get all this information on how to configure everything? I am trying to set up the same config but I have the opposite problem.  Marlin won't work but the touch screen does seem to work.  It just says "Marlin Mode" in orange.  I have SKR2, Klipper, TFT35 3.0 E3.  Thank youspacer.png
