I tried to use my raspberry pi model 3b+ as a secondary Mcu to control some cooling fan and lights beside the Arduino Mega 2560 which is the main control board for the printer axis movement related stuff.
Followed every instruction described in rpi as a secondary mcu at: //https://www.klipper3d.org/RPi_microcontroller.html//
changed the printer.cfg according to it as described by the reference document but keeps getting the error…
MCU 'rpi' shutdown: Unable to open out GPIO chip line
Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown
This is my klippy.log:
klippy.log (1.2 MB)
My printer.cfg:
printer.cfg (9.1 KB)
when I am not including those fans and relays in my code everything is working fine that should verify that klipper is working fine and it’s installation is proper but defining the pins as:
pin: rpi:gpiochip0/gpio any pin number
is giving me that error.
I am defining my secondary mcu (Raspberry pi) as ‘rpi’.
I would also like to mention that I was using fluid with klipper before and at there everything was working as they should, then I tried to remote access my printer outside my home network and neither octopi or mainsail worked for me.
This is what my gpioinfo shows also I enabled SPI so that I could control the pins.
