Hello, i'm using PI4B + CB1. I installed KIAUH , Klipper and Moonraker without problem, wifi work perfectly, but i can't connect to the printer the CB1 can't see the MCU wich was previously flashed with klipper. I need to reflash the MCU with some particular USB setting? image

What ls /dev/serial/by-id/ show? What MCu are you using?

MCu is an AtMega 2560

OK I am not sure you can use anything but a BTT board. There is supposed to be new image coming maybe it will work then in the mean have tried recreating firmware on the PI4B+CB1 and reflashing MCU not sure it will work but might try it. Lots off issue with this board and software.

More important is the type of UART->USB chip. For example CH340, PL2303, CP2102. The drivers just might not be included in the system. What does lsusb say?

@frutabruta lsusb say this, it seem it could see usb devices… C8C90BF6-B3E3-4074-91DE-FDE9C3300FAE

So CH340 it is. Try to install drivers using this tutorial: CH340 install

This is image https://github.com/bigtreetech/CB1/issues/29#issuecomment-1236130800 You will need to use nmtui via a monitor to configure wlan0 to get wifi connected the see if you can do your drivers.

rainerschulte commented 2 years ago

I don't have any HDMI Monitor left over. nmtui can also run from command line. This is how I changed my network settings until now. the large hook is WEP3 not compatible. l must switch back to WEP2.
