LCD from big tree tft28 says printer not attached

Software / Firmware SKR Boards
1

I have a skr v1.3 with tmc5160 drivers
I have it flashed with the firmware with the chances needed from 2209 drivers to 5160 and defining tmc_use_sw_spi

I got this tft28 from big tree and flashed it with the firmware in their site… but the lcd says" printer not attached" .

Porterfield says the codes are uploaded on the skr when I use M105

Any idea what the issue might be here?

Did you try Scale Issues with my Lowrider 2

3

Yup I have changed and tried different baud rates

4

Just to be sure: did you also attach the black (ribbon) wires (and the right way around)?

5

only have a 5 pin connector which goes in one way

6

On the TFT it goes only one way, but on the SKR board it can be plugged in the wrong way…

7

when i plug it on the skr the other way the screen is just black

8

Did you define the ports right?

#define SERIAL_PORT -1
#define SERIAL_PORT_2 0
#define BAUDRATE 250000

yup

Can you show a photo of the back side of the TFT (with cable plugged in)?

Which firmware did you flash? The touchscreensoftware? Can it be that your screen is not compatible with this software and you have to flash: BIGTREETECH-TFT2.8/firmware at master · bigtreetech/BIGTREETECH-TFT2.8 (github.com)

Hello

I was facing similar issue with BTT TFT70 with latest marlin 2.0x suffix, and to solve this issue I recompile the firmware and redeploy into the TFT and it solves the issue.

Please note that for me icons have changed, it seems the look is a little bit different…
