Screen failure: the system seems to reboot at the startup animation; this cycle is endless. However, the printer remains fully functional via the intranet interface. I just can no longer control it manually. Any ideas?
Is a new issue to me.
Bootloops are a common problem but normally klipper/moonraker never start.
Can you use the web UI to stop Klipperscreen?
Can you get a SSH session? If so I’d use kiauh to uninstall klipperscreen. Then on a reboot the screen should stay in text mode.
I could reach Stop Klipperscreen by UI but it had no visible effect even after hard rebooting. Screen still cycles on the graphic intro
Can you establish a SSH connection?
Like already mentioned from @cardoc, try to connect via SSH. You can also just grab a USB drive, copy the original update.deb on it, connect it to the Klippad and let it do a Softwareupdate. No data loss, no SSH.
