printer.cfg for Klipper Pandapi V2.9 Uart

Hi all,

I have been able to get my printer mostly working with klipper and octoprint. The last 2 things I want to irpn out is fan control and UART connection for tmc2209s.

With my current config (shown bellow) I can use my printer as intended except for my part cooling fans which always stay on even if I hit fan off in octoprint. Does anyone have suggestions on how I can get my fans under control?

Also, my motors are not as silent as I'd like them to be. I believe its because the current stand alone implementation doesn't use stealth chop. Does anyone know how I can fill out the sections bellow to get uart set up? I tried setting all the uart_pin sections to PB10, but klipper doesnt like that PB10 is shared like that.
