Panel reference
Printer identity + system status
Read-only panel showing the printer's identity and the key system facts you might need: serial number + model on top, six cards below covering hostname, LAN IP, uptime, free disk, total print time across the machine's life, and the longest single print. Useful when filing a support ticket — the team will ask for most of these values.
Model + serial.
Printer model in big green type (read from /etc/machine-serial) and the unique serial number underneath in monospace. The model determines which Klipper config the printer boots with; serial is your unique identifier — quote it on support tickets.
Network name.
What the printer calls itself on the LAN (e.g. qlm-215.local). Useful for opening Mainsail / Fluidd from another device — type http://hostname.local in your browser.
LAN IPv4.
The printer's address on your local network. Used for SSH access, for slicer uploads, and for everything the cloud tunnel proxies. If this is blank, your network's broken — check WiFi.
Time since last reboot.
How long the Raspberry-Pi / CB1 host has been running since its last reboot. A long uptime is healthy. Sudden short uptime (e.g. minutes when you've been printing for hours) means the host crashed or rebooted — check Info → uptime after any oddity.
G-code storage available.
Space left for new G-code files on the printer. When this drops under ~1 GB, delete old files from the Print panel or via Mainsail. Klipper logs eat ~50 MB per week; an SD card at 0 free will cause silent failures.
Lifetime print hours.
Cumulative hours this machine has spent actually printing (counted across all jobs, all time). Useful for maintenance scheduling — most printers want belt re-tension every 250-500 hours, hot-end clean every 100 hours.
Single-job record.
How long the longest single print was, ever. Mostly a fun stat. But also a confidence indicator — if your longest print is 4 hours, plan to babysit anything longer until you know the machine handles it.
