CB1 uses a custom IO arrangement, check my post here: https://github.com/bigtreetech/CB1/issues/14#issuecomment-1264658542 Just take a `PC` PIN and use my "guide"; I tried with `PC8`, `PC10` and `PC15`

I'm using latest Klipper image of CB1 OS, the V2.2.0. I just tried and I have the same problem. If I set the type as `gpio`, I get the permission...

I just found the solution. Add the following lines in your `moonraker.conf`: ``` [power my_device] type: gpio pin: gpio78 ``` Create a new udev rule as `/etc/udev/rules.d/60-gpiod.rules` : ``` #...

You can run `sudo cat /sys/kernel/debug/gpio` to check if a GPIO is already in use and by which process/service. In my case `gpio75` is used by `spi1 CS0`

After 6 weeks the GPIO PINOUT for the CB1 is still a mistery for BTT/Biqu. The CB1 is currently useless for whom needs GPIO pins. I did some research and...
