SKR 1.4 Turbo not visible on pc via usb #571

Closed Navally closed 1 year ago

Navally commented 1 year ago

Hi there! I bought an SKR 1.4 Turbo to my Anet ET4+ and it worked perfectly but when i mount ESP-01S to that MB and flashed marlin with configuration Serial port 1: 3, Serial port 2: -1 then i cant connect it with my PC via USB cable. I tried to flash older configuration with Serial port 1: -1 and Serial port 2: 0 it still don't connect with PC. Any idea where is the problem? Thanks!

The way you configured it is fine. option -1 activates the USB port option 0 activates the serial port of the TFT connector option 3 activates the serial port of the WIFI connector

Can you send the configuration files?

Marlin.zip

The ports are defined correctly. But why are you compiling an old version of Marlin?

Navally commented 1 year ago

I had this version, and latest from marlin github. On both versions is the same with USB connection.

I have the same board, + TFT display + ESP-01S and the USB port works for me.

After connecting the printer to the PC, check whether you have a problem with the drivers on the PC

Navally commented 1 year ago

Drivers are ok, on second PC is the same.

Thanks for your time! I think there is a problem with chip lpc1769 and i contact with the seller and he send to me second MB.
