Reporter @iitazz uploaded slicer output to Bambuddy, clicked Print,
and the printer rejected every job with "Printing stopped because
the printer was unable to parse the 3mf file". Support bundle showed
the stored library file ended in .gcode (not .gcode.3mf), and
background_dispatch.py appends ".3mf" to filenames that don't
already end in .gcode.3mf/.3mf — so raw gcode shipped to the printer
named .gcode.3mf and the firmware's 3MF parser choked. Same shape
also surfaced as "File is not a zip file" on Bambuddy's own plate
parser.
New validate_print_file_upload() helper in library.py runs at upload
time:
- Reject filenames ending in .gcode (but not .gcode.3mf) with a
clear message — Bambu printers need .gcode.3mf zip containers,
not raw gcode.
- For .3mf / .gcode.3mf uploads, verify body starts with PK\x03\x04
(ZIP magic); reject otherwise pointing at the slicer's "Export
Plate Sliced File" action.
Applied to every relevant upload route: POST /library/files (covers
File Manager + printer-card drag-drop), POST /archives/upload,
POST /archives/upload-bulk (rejects per-row so one bad file doesn't
abort the batch), POST /archives/{id}/source, POST /archives/upload-source.
Runs after _resolve_upload_destination so folder-permission errors
(403 readonly, 400 missing-path, 409 collision) still take precedence.
STL / image / other non-print uploads bypass the validator.
FileUploadModal frontend fix: the modal auto-closed after every
batch regardless of per-file results, so a 400 rejection was captured
but invisible. Now:
- Errors render inline as red text under the file row instead of
as a hover-only title tooltip.
- Modal stays open if any file ended with status='error', so the
user can read the backend's remediation message before closing.
- Successful-only batches still auto-close as before.
UploadModal (bulk archive) was already showing inline errors and
not auto-closing — no change needed there.
