Do you have the same serial speed set? Did you use the correct coneltor? Have you checked the TFT cable to see if it is faulty?
I used the TFT connector and I ohmed the cables, they are good. and yes I have the serial speed set to 115200 on the screen and marlin. Im using marlin 2.0.9.3 does this matter? I read something that says I may need marlin 2.1 or higher.
Yes 2.0.9.3 is an old version, but it should not prevent the display from communicating with the SKR. At most, some functions will not be available.
I just finished building marlin 2.1.2 for the skr 3 ez. I used a premade firmware from btt but marlin has a built in skr 3 ez board. lets see if it works
Update: new firmware didn't solve anything. Still have no printer connected.
Mine wasn't working either, i had the wrong envs selected in Platformio
[platformio] src_dir = Marlin boards_dir = buildroot/share/PlatformIO/boards default_envs = STM32H743Vx_btt include_dir = Marlin
Instead it should be
[platformio] src_dir = Marlin boards_dir = buildroot/share/PlatformIO/boards default_envs = STM32H723Vx_btt include_dir = Marlin
But there is no such thing as STM32H723 only 743
Are you using the newest marlin ?
Yes Marlin-Bugfix 2.1.x
First you need to fix the motherboard in configuration.h It should be for skr 3ez not regular
Can you show me the valid names

Double check the number on the board chip
Im about to jump off a bridge, downloaded bugfix for the 3rd time tonight and now 723 shows up
Make sure your board chip end with 723 too mine does
THank you for your patience but that was wild
No worries, I been through the same thing just trying to help with my little knowledge
TFT is now connecting to my skr 3 ez, you are a lifesaver. thank you for all of your help.
You're welcome
hello i also have the same issue except that my chip matches the environment in platform .io i also cant get the marlin mode working
@giri456 Your description of the problem is too general. Write what HW you have, describe exactly your problem. Send the configuration files for SKR and TFT that you used. Send photos of the cable connection between SKR and TFT
@radek8 Sorry about that, first time on the forums. I am using a skr 3 ez and trying to connect it to a tft24 v1.1 in both marlin and touchscreen mode
For the tft i used the files found here I directly coppied and pasted the ones that were for the tft24.
this is my marlin config converted to text file so i could upload here configuration_adv.txt configuration.txt
Sorry forgot about the photo.
Also send the config.ini file, with your edit
i used the default config.ini that is on the big tree tech github for this screen
The default communication speed of the serial port is 115200 for TFT Your Marlin configuration is 250000 You must have the same baud rate configured. (for touch mode)
In Marlin, enable the option define M115_GEOMETRY_REPORT
made the changes and did them on a fresh copy of marlin configuration.txt configuration_adv.txt
Got a few more pictures of what happened in marlin mode
@radek8
I also tried adding this into config.h still doesnt work
@radek8 i managed to get the touch mode to work i think it looks like this now
But Marlin mode is still not working
How long are your EXP1 and EXP2 cables? It looks like electromagnetic interference on the cables
If Touch Mode works for you, you don't need Marlin Mode. I haven't used Marlin mode in over a year.
@radek8
I have uploaded a picture of the length of the cable. To confirm I can use a sd card on the tft with just the touch mode cable?
To confirm I can use a sd card on the tft with just the touch mode cable?
Yes, you can use the SD card on the TFT with a serial (5pin) cable. If you set in Marlin:
Then the mini SD card on the SKR will also be available in touch mode.
Ok thanks
@radek8 i finished my config.h and adv.h. i just tried flashing the firmware today and the file doesnt get renamed. the tft says eeprom data size error
Did you compile for the right platform? After updating the marlin, you should initialize the EEPROM
@radek8 I have compiled to the right processor in platform.io. But it still doesn’t rename the file. I also tried uploading it with only the .bin file and no .cur file. I also tried to rename the .bin file to full uppercase.
Are you updating Marlin?.
Use the microSD slot on the SKR.
Use an SD card that is 8GB or smaller.
How big is your BIN file?
What is the designation of your processor on the SKR?
Turns out it was a sd card problem. But now after flashing my z2 stepper won’t move or lock. It’s like it’s not getting power.
nvm got everything working much thanks @radek8
I see that you don't have a USB port activated in Marlin. Are you going to use the USB port on the SKR? (On connection with Pc)
Hello, I am having the no printer attched issue with my printer. I have an Ender 5 plus with an SKR 3 EZ and a TFT50 V3.0.1. I will provide my configuration.h below but I have followed the manual, and I have gone through every no printer attched post I can find. Nothing helps, my current settings for the tft are Serial Port = 1, Serial Port 2 = -1, Serial Port 3 = 3 as this is what the manual reccomends. I have tried every combination that I can think of but maybe I am missing something. I would appreciate some help. It wont let me upload the .h file so here is the .txt file for config Configuration.txt Configuration_adv.txt
