Hello, No access to GPIO without root. It is necessary for Moonraker.
in group
grep gpio /etc/group
gpio:x:1001:isp
isp@3dprinter:~$ echo 10 /sys/class/gpio/export

but
isp@3dprinter:~$ ls -lL /sys/class/gpio/
total 0

and
isp@3dprinter:~$ sudo cat /sys/kernel/debug/gpio
gpiochip0: GPIOs 0-223, parent: platform/1c20800.pinctrl, 1c20800.pinctrl:

if i make

then all ok

What am I doing wrong? I need to access GPIO without root to work with Moonraker. Thanks!
