OTA is for updating an already working device from the BambuHelper web UI.

Full is for first-time flashing, recovery, or ESP Web Flasher use.

First-time flashing? Easiest path is the hosted web flasher at keralots.github.io/BambuHelper - pick your board in the dropdown, click Install, and the browser handles bootloader + partitions + firmware in one go (no downloads, no flash offsets). The -Full.bin files below are only needed if you prefer the generic ESP Web Flasher or are flashing one of the community / beta boards that the hosted flasher doesn't list yet.

Updating from v3.7.5? OTA the matching -ota.bin for your board. Settings are preserved.

Changes

New board

• Panlee SC05_X (ZX2D80CE02S) - support for the Panlee SC05_X 2.8" module (WT32-S3-WROVER, 240x320 ST7789 over an 8-bit parallel bus, capacitive touch). Available in the hosted web flasher and the release binaries. Thanks to @nunnypern for contributing the board. (#147)

New features

• Clock date size - the Clock card in the web UI now has a Date size setting (Auto / Normal / Medium / Large), so you can make the date under the clock larger. Auto follows the clock's time size, so wider displays show a bigger date by default. (#148)

Fixes

• Smart plug no longer auto-switches off after a calibration print - running a Bambu Studio calibration (flow rate, pressure advance, temperature tower, etc.) needs the printer to stay powered so Studio can read back and save the results. BambuHelper now recognises calibration and device-initiated jobs and skips the smart-plug auto-off for them, so the calibration wizard no longer gets cut off. (#149)
• Friendly calibration names on screen - calibration prints now show a readable label (e.g. "Flow calibration") instead of the raw internal gcode filename.
• QD ES3N28P colour inversion - the display-inversion handling was unified across boards, which fixes the ES3N28P "Apply flips the colours" bug. If you had previously ticked Invert colours on an ES3N28P as a workaround, colours will flip once after this update - simply untick it to get the correct colours.
