Case library
Submit a failed print case after one clear test.
The best submission is not a perfect write-up. It is a visible failure, the exact printer context, one thing you changed, and what happened next.
Use a test STL or repeat the same small part so the result is comparable.
Submit the printer context, the one variable changed, and before / after photos or logs.
Photos That Help
- Front photo of the failed part under bright, even light.
- Side photo showing layer lines, lifted corners, blobs, or shifts.
- Close-up of the first layer or failure area, not only the whole model.
- Nozzle and build plate detail if the issue involves clogging, adhesion, or PETG release.
- Slicer settings screenshot for temperature, retraction, flow, speed, and seam placement.
- Exact Klipper error text and the relevant log lines for firmware stops.
Anonymous By Default
- Do not include faces, addresses, serial numbers, or private files in photos.
- Cases may be summarized anonymously in future diagnostic examples.
- Images are reviewed before publication; submission does not guarantee they will be used.
- Print Fixes does not need personal information to learn from a failure pattern.
What makes it publishable
A useful case has proof on both sides of one change.
The failed area close enough to see line shape, corner lift, strings, blobs, or log text.
A small STL or repeated print section where only one variable changes.
Same angle and lighting so the result is comparable instead of a new anecdote.
Printer, slicer, firmware, material, nozzle, bed surface, and recent maintenance.

Before submitting
Run one small confirmation test if the printer is safe.
A before/after pair from the same STL is much more useful than a single failed full-size print.
