The fastest failed-print diagnosis starts with when the print failed: before layer one, after a few layers, mid-print, near supports, or near the finish. The failure timing points to the most likely cause.

What usually causes it
- First-layer/adhesion failure
- Nozzle clog or filament jam
- Mechanical shift or collision
- Support strategy failure
- Material moisture or temperature mismatch
Do this in order
- Take a clear photo before removing everything.
- Identify the failure timing and location.
- Check the first layer, nozzle, support preview, and material condition.

FAQ
Fast answers
What should I check first?
The fastest failed-print diagnosis starts with when the print failed: before layer one, after a few layers, mid-print, near supports, or near the finish. The failure timing points to the most likely cause.
Should I change many slicer settings at once?
No. Make one controlled change, test again, and save the working result in Profile Vault. Random setting changes make print failures harder to diagnose.
When should I use AI Doctor?
Use AI Doctor when the symptom is unclear, when the print failed in multiple ways, or when you want to connect a failed-print photo to the right guide path.
