Send the configuration files and photos involved.

[Aleks1967]

Configuration h.txt Configuration adv.txt

[Aleks1967]

I sent configuration files with txt extension, because the original ones are not accepted by the site

[Aleks1967]

What should be in the photos?

[Aleks1967]

here is a photo of the pinout of the skr 1.4 turbo board pin TXO is in the middle of the pad, and in the TFT pad 24, it is 2 (UTX). in the cable the wires are not shifted relative to the location of the pins I have changed the location of the wires, it did not change anything, the screen when you connect the 5 pin wire is white, disconnect the wire and the display begins to show the picture, In Configuration adv, I did not change the lines for the touch screen, I need it only in Marlin mode

Send a photo to see the connections and orientations of the EXP1 EXP1 and TFT tables on both sides.

In Marlin you have a speed of 250000 In config.ini set serial_port: P1: 7 P2: 7 P3: 0 P4: 0

[radek8]

Update the display to the latest FW. If the TFT does not respond to the touch, perform a reset with the reset.txt file. Then upload the configuration with the config.ini file.

Send those photos. It looks like a badly connected cable

[Aleks1967]

[Aleks1967]

the marlin version installed for the display is the latest In config.ini set serial_port: P1: 7 P2: 7 P3: 0 P4: 0 - What needs to be fixed? Is it the display config?

[Aleks1967]

[Aleks1967]

should be corrected here? it should be set to -6, which corresponds to 250000 Do I understand it correctly?

[kisslorand]

No, 6 corresponds to 115200 ("115200: 6"). For 250000 select 7 ("250000: 7"). As you can see in the config.ini:

• OFF (port disabled): 0
• 2400: 1
• 9600: 2
• 19200: 3
• 38400: 4
• 57600: 5
• 115200: 6
• 250000: 7
• 500000: 8
• 1000000: 9

[radek8]

Check the serial cable (black 5 pins). Take a picture of the color markings on the cable.

[radek8]

The cable seems to me to be rotatable by 180 degrees

[Aleks1967]

I changed the data in the config.ini file, reflashed, nothing has changed, turned it 180 degrees EXP2 no result

[Aleks1967]

Here is a 5 PIN cable

[kisslorand]

You are changing the comment, the explanation itself, not the parameter You should have this: serial_port:P1:7 P2:0 P3:0 P4:0

[Aleks1967]

with a 5 pin cable figured out, not properly connected to the motherboard, although the video on YouTube single cone connected to the right side, white screen ceased to be, reset using reset.txt file touch settings, the touch screen on the display began to respond to click and open tabs, Marlin mode does not work, before the inscription on the display was yellow letters, now whit e

[radek8]

Yes, it's as I expected. You have a 180 degree rotation of the serial cable.

[radek8]

Also check cables EXP1 and EXP2. Orientation is correct. But make sure you don't cross them.

[Aleks1967]

made, here is the picture, no change, the inscription marlin mode has become red The touch screen now works properly. marlin mode does not work,

[radek8]

Your problem is that you connect everything according to some instructions on Youtube and when it doesn't work, you try to turn the connectors headless. This approach will destroy something. Try to engage reason. download the pins and connect the cables of the same pins on the SKR to the same pins on the TFT.

[radek8]

I changed the data in the config.ini file, reflashed, nothing has changed, turned it 180 degrees EXP2 no result

You must not rotate the EXP2 connector He was well connected in the first photos. Man, do what we advise you to do. don't make more mistakes.

[kisslorand]

I am speechless... I cannot compete with this!

[Aleks1967]

I flashed the display with this file, the marlin mode does not work

[Aleks1967]

I flashed, rebooted the printer, the marlin mode does not work

[radek8]

Send the current configuration that you last uploaded to SKR and TFT send photos of current connection cables.

[Aleks1967]

config.txt The skr 1.4 configurations are the same as above, the stubs are as they should be, the firmware for the display is 1.27,

[Aleks1967]

[Aleks1967]

Configuration.txt Configuration_adv.txt here is the configuration with the touch screen display, I had to uncomment the lines regarding the 2 lines of the Z-probe. since I do not have a bl-touch sensor

[Aleks1967]

I upgraded the skr 1.4 motherboard. the touchscreen display says connection - no, Marlin mode - does not work configuration files posted above, tell me what I did wrong, thank you in advance

[radek8]

Do you have cables EXP 1 and EXP2 connected according to the picture?

[Aleks1967]

Yes

[radek8]

You did not send the configuration file config.ini. In the SKR board is Marlin in the TFT board is the FW of the touch screen. These are two different SWs that must be configured. Do you know how to update both?

[radek8]

The display is new but the SKR board is full of dust. So he ran before the upgrade. What display did you use before?

Now the connection is OK. It should work. I don't think you upgraded the SKR or the TFT configuration

[Aleks1967]

config.txt Here is the configuration for the display

[Aleks1967]

updated everything, I print through the slicer, I can not connect the display for half a year, this board with a display did not work, the old board burned out along with the display, skr bought earlier, then bought a display, thought it had no firmware and reflashed it immediately, I could not connect, well, looking for options from whom to ask, started asking questions here

[radek8]

If you had a display connected to the SKR that burned out, it is quite possible that the inputs on the EXP1 and EXP2 connectors of the SKR board also burned out.

[radek8]

Maybe you could get a touch screen that doesn't use the EXP1.2 connectors

[radek8]

if you upload the configurations you last sent, the display can work in both modes. If the SKR board has burnt inputs, Marlin mode will not run.

[Aleks1967]

The sensor does not work, says no connection

[Aleks1967]

[radek8]

Open on the touch screen. Menu, Settings, S. port, See what speed you have set to 1. Printer.

[Aleks1967]

the parameter is set correctly 250000, I click on connect, the inscription "connection" appears if I click on the button writes TFT listening mode and nothing work s
