Basic Information:

Printer Model: Creality Ender 3 S1 Pro
MCU / Printerboard: CR4NS200141C13
Host / SBC Inovato Quadra running Armbian 22.08.0-trunk Bullseye with Linux 5.15.63-sunxi64

Moonraker Log.txt (6.7 MB)

Describe your issue:

While performing the latest software updates for klipper and moonraker I temporarily lost power to the Host and MCU. I was able to install the updates but afterwards undable to restart Klipper with the Message “Klippy not connected”. I have rebooted the host and printer multiple times, and restarted the Orca Slicer 2.1.1 software with no change.

I tried a prior recommended fix:

  1. nano /home/pi/printer_data/systemd/klipper.env
  2. Replace /home/pi/printer_data/comms/klippy.sock by /tmp/klippy_uds

but got the error message:

[ Error writing /home/quadra/printer_data/systemd/klipper.env: Permission denied ]

In my very limited experience, I did not see any error in the klippy.log but did see what might be an issue in the moonraker.log so it is also attached.

Thanks in advance for your help getting me reconnected.

This can seriously mess up your system. Finding all the things gone awry, likely needs quite some administrative experience and time. In addition, the Linux distribution you are running on is ages old.

I’d recommend to:

  • Backup your configuration
  • Get a recent Armbian image and burn it to a new SD card
  • Install Klipper and its ecosystem with KIAUH
