How to use this vault
Search by symptom first, then by printer or material. Open the closest guide, follow the diagnosis order, and use AI Doctor when you need a second look at photos or settings.
What is included
First layer, extrusion, materials, supports, printer hardware, slicers, resin, commercial quality, print farm workflow, and model-specific fixes.

destroying model features.Bridge Lines Sagging Under PrintsBridging: Improve bridges with cooling, speed, flow, temperature, and geometry choices.Overhangs Curl Up Into NozzleOverhangs: Fix upward curling overhangs that hit the nozzle and cause layer shifts.Walls Look Wavy on CurvesSurface Quality: Diagnose wavy curved walls caused by speed, acceleration, cooling, resonance, or over-extrusion.Ringing After Sharp CornersMotion Quality: Reduce ghosting and ringing around corners without killing print speed.Layer Lines Randomly Change WidthExtrusion Consistency: Fix inconsistent layer width from spool drag, partial clogs, temperature swings, or extruder slip.Top Surface Has ScratchesTop Layer: Stop nozzle scratching across finished top layers and improve ironing/travel settings.Bottom Surface Too Glossy or Too RoughFirst Layer: Tune bottom finish on PEI, glass, textured plates, and smooth build surfaces.Infill Shows Through Outer WallsWall Quality: Reduce visible infill pattern on the outside of prints.Gaps Around PerimetersExtrusion: Fix gaps between walls, top surfaces, and internal perimeters.First Layer Perfect But Second Layer BadLayer Transition: Diagnose transition problems between first layer settings and normal print settings.Prints Fail After Nozzle ChangeMaintenance: Recover from wrong nozzle size, poor hot-tightening, leaking hotend, and slicer mismatch.Hotend Leak Around Heat BlockHotend: Fix filament leaking around the nozzle or heatbreak safely.Filament Sensor False RunoutHardware: Stop false filament runout warnings caused by dust, sensor alignment, or brittle filament.Spool Drag Causes Under ExtrusionFilament Path: Fix prints that starve because the spool does not unwind cleanly.AMS Fails to Pull Back FilamentBambu AMS: Diagnose AMS retract failures, brittle filament, spool resistance, and PTFE path friction.Color Swap Leaves BlobMulti Color: Clean up manual color changes, purge blobs, and restart artifacts.Pause at Height Leaves Layer ScarSlicer: Reduce scars after pause-at-height color changes, magnet insertion, or hardware inserts.Magnet Holes Too TightFunctional Parts: Tune embedded magnet holes for print tolerances and clean assembly.Heat Set Inserts Melt PartFunctional Parts: Install heat-set inserts without bulging, melting, or splitting printed parts.Print Surface Contaminated by FingerprintsBed Adhesion: Restore bed adhesion after oil, dust, glue residue, or soap film.Glue Stick Builds Up on BedBed Maintenance: Clean and manage adhesive buildup without damaging the build plate.PEI Sheet Bubbles or PeelsBed Maintenance: Decide whether to clean, reattach, flip, or replace a damaged PEI surface.Glass Bed Not StickingBed Surface: Fix adhesion on glass beds without over-squishing or using too much adhesive.Nozzle Hits InfillInfill: Reduce nozzle collisions with infill using pattern choice, Z-hop, flow, and temperature.Grid Infill Causes ClickingInfill: Fix extruder clicking or nozzle collisions caused by crossing infill patterns.Fast Draft Profile Looks TerribleSlicer Profiles: Make draft profiles useful without ruining walls, seams, and first layers.Quality Profile Takes Too LongSlicer Profiles: Find the settings that matter most so quality prints do not take unnecessary days.Orca Profile Changed After UpdateOrca Slicer: Recover calibration after a slicer update changes defaults or profile behavior.Cura Profile Gives Different SizeCura: Fix dimensional differences after switching slicers or importing profiles.Klipper Config Not SavingKlipper: Fix confusion when Z-offset, mesh, pressure advance, or input shaping does not persist.Neptune 4 Pro Bed Mesh ConfusionNeptune 4 Pro: Understand mesh, Z-offset, screws tilt, and saved config on Neptune 4 Pro style printers.Ender 3 Keeps Losing LevelEnder 3: Fix leveling drift, springs, warped beds, loose wheels, and inconsistent Z home.Prusa First Layer Live Z ConfusionPrusa: Dial in Live Z without chasing bed cleanliness, filament, or sheet profile problems.Resin Prints Stick Too Hard to PlateResin: Reduce excessive build-plate adhesion without creating failed first layers.Resin Supports Leave CratersResin: Reduce craters and scars from resin supports with orientation, support size, and curing order.Resin Hollow Prints CrackResin: Prevent hollow resin models from cracking, leaking, or trapping uncured resin.SLA Detail Soft After CuringResin: Fix soft or over-cured resin details by tuning exposure, wash time, and cure time.Commercial Prints Need Better FinishSelling: Create a repeatable finish checklist before selling printed products.Customer Says Part Is Too WeakSelling: Diagnose customer strength complaints through orientation, walls, material, and expectations.Packaging Damages 3D PrintsSelling: Pack fragile display models, terrain, and printed products so they survive shipping.Batch Prints InconsistentPrint Farm: Keep multiple copies consistent across bed positions, spools, printers, and slicer versions.Printer Maintenance Before Big JobMaintenance: Use a pre-flight checklist before long, expensive, or customer-facing print jobs.Weekend Print Queue PlanningWorkflow: Plan multi-day printing batches without clogging the printer with risky overnight jobs.AI Doctor Photo ChecklistAI Doctor: Take better troubleshooting photos so AI Doctor can diagnose failures faster and more accurately.Failed Print Recovery Decision TreeTroubleshooting: Decide when to reprint, adjust settings, split the model, or abandon a bad print setup.
