Bambu Lab firmware updates: precautions before you tap OK

Read the release history, update Studio and Handy first, never cut power mid-update, and recalibrate afterwards. Plus the offline microSD option.

Klipper update checklist (host, MCU, and config changes)

Klipper updates come in two halves: the host software and the micro-controller firmware. Here's the order that avoids a printer stuck in a version-mismatch error.

OctoPrint itself updates cleanly; plugins are where things break. Use the bundled Backup & Restore and Software Update plugins the way they're designed.

Five minutes of Git setup turns every config change, SAVE_CONFIG, and update into a diff you can review and undo.
