The Problem

3D Print Failures Are Expensive

Power outages, filament tangles, firmware crashes — any of these can kill a 12-hour print. Without a resume option, you're stuck.

💸

Wasted Filament

Restarting a print from scratch means burning through filament you already used. A failed 300g print costs real money.

⏰

Wasted Time

That 18-hour print that failed at layer 200? Without resume, you're waiting another 18 hours for a re-do.

😤

No Easy Fix

Manually editing G-code to resume is tedious, error-prone, and risky. One wrong move and you crash the nozzle into the part.

The Solution

FailFixer: Resume Any Failed Print

A lightweight desktop tool that generates safe resume G-code from your original file. No printer mods. No firmware changes.

What It Does

FailFixer reads your original G-code, lets you pick the exact layer or Z-height where the failure occurred, and generates a new file that safely resumes from that point.

Preserves temperature, extrusion mode, and unit settings
Injects a safe resume header (no Z-homing collisions)
Supports absolute and relative extrusion modes
Handles files up to 50MB in under 3 seconds
Deterministic: same inputs always produce the same output
Primary activation via Lemon Squeezy key with offline grace mode
