Trouble with USB Connection
June 22, 2024 11:04PM
I'm trying to get Octoprint (or anything at this point) to connect to my SKR2 running Marlin on a new machine. The only difference between this setup and previous ones is, I've got a BTT MINI12864 V2 using the EXP1 and EXP2 ports on the SKR2, vs the CR10 display that only used one of them.

I've tried different USB cables, a couple of different SKR2 boards (running the same firmware), a couple of raspberry pies and my PC. They always sense when I plug the SKR2 in, but can't make the actual communications connection. I've attached my config files here and would greatly appreciate any advice here. Thank you.

The only serial port you have enabled is the TFT connector (ie #define SERIAL_PORT 1)

This board has 3 serial ports

-1 this is the USB cable
1 this is the TFT port
3 this is the WIFI port

remove the // from
//#define SERIAL_PORT_2 -1
to enable the USB port

Or of your not actually using the tft port change #define SERIAL_PORT 1 to #define SERIAL_PORT -1

THANK YOU! This got me connected. I went back and looked at the firmware for my other machine and it does indeed have SERIAL_PORT_2 -1 enabled. I was too focused on the first port and I've been fighting too many other things on this machine, afraid my brains turned to mush.
