"Nenhuma impressora conectada!" Erro com btt SKR 1.4 Turbo

[Laidner]

Hi! I bought SKR1.4 Turbo + BTT-TFT24-V1.1 a while ago and used both to upgrade my Longer Lk4 Pro printer. I confess that I'm a layman and I don't understand much about these settings! I followed a video: https://www.youtube.com/watch?v=gVMiEtfK9S8 to help me but I'm having a problem trying to connect that you can't control. Always appears on the screen "No printer connected"

My configuration: MTB SKR V1.4 Turbo Marlin 2.0 MTB TFT24-V1.1

thanks!

In Merlin you have to enable serial port 0 and set the same serial port baud rate on both TFT and SKR.

If you have it set up correctly, read this https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware/issues/2382

Thank you for replying! I used serial port 0 and -1 On Baudrate I tried 57600, 115200, 250000 on both Marlim and screen I'm Brazilian, I followed this video I'm Brazilian, I followed this video: https://www.youtube.com/watch?v=gVMiEtfK9S8&t=1654s

I'll check and try to correct the error with this link you sent me!

I know I will have difficulty understanding, it will probably take time to solve! A little patience please!

Does Merlin mode work for you? Users with the same problem have written here several times. There may be a port configuration or speed error. (you wrote that you checked) The serial cable (black 5-pin) may also be defective. Check the cable !!

Another option is faulty serial port pins on the SKR board or on the TFT. (common defect see link) If the pins on the SKR are defective, the pins from the wifi connector can be used. I need to activate the correct serial port in merlin.

If the pins on the TFT were defective, the pins from the EXP connector could be used. Then you would no longer be able to use the merlin mode, but it won't matter if the touch mode is functional :-)
