Find the fix by symptom: prints that fail, fillets that break, parts that do not fit, a misunderstood agent, red steps, voice problems and export issues. Each with causes, fixes and how to avoid it.
Match what you see on the failed print (spaghetti, drooping, curling, snapped layers) to its cause, and fix it in the model rather than only in the slicer.
A fillet or chamfer step turned red or produced nothing. The usual causes (radius too large, tangent edges, wrong order) and how to fix each.
A lid that is too tight or too loose, a screw that will not go in, a board that does not fit: diagnose whether it is the design, the printer, or the measurement.
The preview is not what you meant. Find out whether the cause was selection, missing numbers, a mixed-up request or the wrong mode, and recover without losing work.
What a red step means, what each error type tells you, and how self-healing history lets the agent explain and repair the break.
Fix microphone permissions, wrong input devices, browser support and plan limits so push-to-talk and Live voice mode work.
The file is missing, the wrong format, the wrong size, or shows several pieces stacked together. Find the cause and get a clean print file.
A model built from a photo is too big, too small, or distorted. How scale is estimated, why it goes wrong, and how to correct it with one trusted measurement.
