Print Fail Fix Card
For the 3D printing hobbyist whose print just failed at midnight and who is one tab away from posting a photo to r/FixMyPrint hoping someone diagnoses it before morning. Tell the tool the printer, slicer, filament, the failure symptom and whatever settings you remember, and one structured pass returns a ranked diagnosis card: two or three ranked candidate causes with per-cause settings-delta tables in your slicer's dialect, a one-line physical-inspection step, a short test-print recipe with a time estimate, an assumptions receipt list for every blank field, and a one-line closing message that routes you when the failure is actually a resin print, a structural part, or a thermal-runaway signature.
About this tool
What does print fail fix card do?
For the 3D printing hobbyist whose print just failed at midnight and who is one tab away from posting a photo to r/FixMyPrint hoping someone diagnoses it before morning. Tell the tool the printer, slicer, filament, the failure symptom and whatever settings you remember, and one structured pass returns a ranked diagnosis card: two or three ranked candidate causes with per-cause settings-delta tables in your slicer's dialect, a one-line physical-inspection step, a short test-print recipe with a time estimate, an assumptions receipt list for every blank field, and a one-line closing message that routes you when the failure is actually a resin print, a structural part, or a thermal-runaway signature.
How does Print Fail Fix Card diagnose a 3D printing failure?
Type your printer (Bambu A1, Prusa MK4, Ender 3 V2, Elegoo Neptune, Voron, and so on), filament type (PLA, PETG, ABS, ASA, TPU, Nylon, PC-blend), slicer (PrusaSlicer, Cura, OrcaSlicer, Bambu Studio, or SuperSlicer), and the symptom you saw (stringing, warping, under-extrusion, elephant foot, layer shift, poor adhesion, blobs, ghosting, pillowing, zits, delamination, bridging failures, overhang droop, first-layer issues). Optionally add your current nozzle temp, bed temp, print speed, retraction distance and speed, layer height, and a free-text note. One structured pass returns a ranked diagnosis card: two or three candidate causes in descending confidence order, each with a settings-delta table in your slicer's exact pane names, a one-line physical-inspection step, a short test-print recipe with a time estimate, an assumptions receipt list for every blank field the model had to infer, a safety-notes list for every guardrail that fired, and a one-line closing message. It reads out loud in order so you can run it from your phone at the printer.
What causes stringing, warping, or under-extrusion on an FDM printer, and will this tool actually fix it?
Stringing is almost always retraction tuned too short (direct-drive printers want 0.5 to 1.5 mm, bowden setups want 3 to 6 mm) combined with nozzle temp running hot for the filament batch. Warping on ABS, ASA, PC, and Nylon is bed adhesion plus ambient draft; the fix is bed temp inside the filament's documented range, a brim or draft shield, and an enclosure. Under-extrusion is usually a partial clog, worn PTFE on the hot side, under-tensioned extruder gears, or print speed set faster than the hotend can melt plastic for that nozzle size. Print Fail Fix Card knows these patterns and encodes them as ranked causes with per-cause settings-delta tables in your slicer's dialect, so you are not reading forum posts in six tabs trying to reconcile which Reddit comment matches your printer family.
Does it support Bambu A1, Prusa MK4, Ender 3, and Voron?
Yes. The tool is built around the prosumer FDM machines hobbyists actually own: Bambu Lab A1, A1 mini, P1S, P1P, X1 Carbon; Prusa MK3, MK3S, MK3S+, MK4, MK4S, MINI, MINI+; Creality Ender 3, Ender 3 V2, Ender 3 S1, Ender 3 Pro, Ender 5, K1, K1 Max; Elegoo Neptune 3, Neptune 4; Anycubic Kobra, Kobra 2, Kobra Max; Voron 2.4, Voron Trident; Sovol SV06, SV07; Artillery Sidewinder; Sidewinder X2; and the common clones. The ranking logic picks defaults appropriate to your printer family (direct-drive retraction distance for a Bambu A1 or Prusa MK4, bowden retraction distance for an Ender 3 V2, CoreXY tuning for a Voron), so the fix card is not generic Reddit advice.
Which slicers does it speak? PrusaSlicer, Cura, OrcaSlicer, Bambu Studio?
All five. Every settings-delta row names the setting in the exact wording your slicer uses and names the pane you open to change it. PrusaSlicer and SuperSlicer get Retraction Length under Printer Settings tab, Extruder 1, Retraction. Cura gets Retraction Distance under Print Settings panel, Travel. OrcaSlicer and Bambu Studio get Retraction Length under Printer Settings, Extruder, Retraction. Nozzle temp and print speed get the same per-slicer treatment. If you type a slicer the tool does not recognize, it picks the closest supported one, uses that dialect, and logs the normalization into the safety-notes receipts so you see exactly what it swapped.
How is this different from just posting to r/FixMyPrint?
A Reddit thread is six people guessing in parallel at midnight, each from a different printer, a different filament brand, and a different slicer. The top-voted reply is often tuned for the commenter's setup, not yours, and you have to translate every answer into your slicer's pane names. Print Fail Fix Card runs a single structured pass that already knows your printer family, your filament type, and your slicer's dialect, so every suggested setting change is already in your language. You get a ranked card with per-cause confidence (likely, possible, long_shot) in seconds, instead of waiting until morning for an answer you then have to translate.
What if my print is a load-bearing or safety-critical part?
The tool refuses to tune settings for structural, load-bearing, or safety-critical parts (motorcycle, car, drone, aircraft, medical, firearm, climbing, childcare restraint, pressure vessel, electrical mains, anything carrying human weight). The failure in those cases is a design problem (material selection, print orientation, infill topology, post-processing, test-to-failure review) and no settings-delta table responsibly addresses it. The card returns a routing message that points you to r/3dprinting with full context or to a mechanical engineer, and logs the refusal into safety-notes with kind structural_part_refused. Your tokens are refunded automatically on refusal.
What about resin printing or thermal runaway?
Resin printing is a completely different workflow (exposure, LCD mask, support islands, FEP release, cure settings) and an FDM fix card would be wrong by construction. If the tool detects a resin or MSLA machine (Elegoo Mars, Elegoo Saturn, Anycubic Photon, Phrozen, Creality Halot, Formlabs, Prusa SL1), it refuses with a routing message to r/ResinPrinting and logs resin_refused. If your notes mention thermal-runaway warnings, smoke, flames, melted shrouds, a thermistor error, or a bed overheating past the configured max, the tool stops the diagnosis entirely, tells you to power the printer down, and points you at a firmware check (Marlin THERMAL_PROTECTION_HOTEND and THERMAL_PROTECTION_BED, Klipper min_extrude_temp and verify_heater) before you re-power. Safety first; the card is not the right surface to fix a fire risk.
What is the settings-delta table and why does it matter?
The settings-delta table is the heart of the card. Each row names one setting (Retraction Length, Nozzle Temperature, Print Speed, Fan Speed, Z Hop, First Layer Height, Flow Rate, Pressure Advance / Linear Advance, Travel Speed, Minimum Layer Time), your current value (or blank if you did not supply it), the suggested new value, the unit, a one-line why, and the exact slicer pane to find it in. On the Quick tier you get one most-likely cause with up to three delta rows. On the Deep tier you get two or three ranked causes with up to five delta rows each. Every suggested value is clamped to the filament's documented safe range (PLA 185 to 230 C, PETG 220 to 250 C, ABS and ASA 230 to 260 C, TPU 210 to 230 C, Nylon 240 to 270 C, PC-blend 260 to 290 C) and any clamp is logged into safety-notes with kind hard_setting_floor_held.
Which tier should I pick, Quick fix or Deep diagnosis?
Pick Quick fix (15 tokens on Gemini Flash Lite) when it is midnight, the print you were going to leave running overnight just failed, you are tired, and you need one confident setting change in your slicer's dialect to try before you go to bed. You get the single most-likely cause, one to three delta rows, a one-line physical check, and a short test-print recipe. Pick Deep diagnosis (25 tokens on Gemini Flash) when a print has failed twice already, when the Quick fix did not resolve it, or when you want the full audit trail: two to three ranked causes in descending confidence, up to five delta rows per cause, every blank-field inference receipted into assumptions, and every guardrail that fired (slicer normalization, blank-field assumption, unit conversion, hard setting floor held, overbroad symptom fallback) listed into safety-notes. Deep is the tier for anyone who wants to see exactly why the card looks the way it does before they re-slice.
Does it work without a subscription, and what happens if the run fails?
No subscription, ever. You spend produde tokens per run: 15 for Quick fix, 25 for Deep diagnosis. Tokens are a prepaid platform credit you buy once and spend across every produde tool, so a hobbyist pays per failed print instead of a monthly SaaS bill in the long stretches of the year when nothing is on the bed. If a run fails at any stage (network error, model refusal, safety guard triggered, pipeline error), the full token cost is refunded to your wallet automatically. You never lose tokens on a card you did not receive.
What does it cost?
From 15 tokens. Pick a tier on the form above. Produde tokens are a prepaid platform credit; buy them once and spend on any tool.
Do I pay if a run doesn't complete?
No. You only pay for results. If a run can't finish, its full token cost stays in your wallet automatically.
