Hi,
I'm trying to install Klipper onto my Sovol Sv01 Pro. I successfully flashed the firmware onto my printer via SD card, but I have been getting this error since my first boot. At first I thought it was just because I didn't have my printer plugged in, but now I do and it's still giving this error. I have tried changing the serial port ID but it is correct in my printer.cfg. The only things I can think of is that 1) I was lied to and the cable I got isn't rated for file transfer, but the pi says it's receiving information, so I'm doubtful about that, too, or 2) the config I found is incorrect. There's no official config so I used one I found on GitHub.

So the file got renamed right? Then you most likely messed up a setting like e.g. the clock reference

how do i figure out what setting my printer's board needs? it's running a creality 4.2.2 board

Why exactly did you buy a creality 4.2.2 board for your sovol printer?

that's what it comes with...

most of the sovols come with creality boards

i agree! one of my first upgrades will probably be a BTT replacement
