Prints failing? Or just not as clean as you’d like? PrintDoc helps you find out why.
Snap a photo of the print right at the printer. PrintDoc reads it and points you to the likely root cause, plus the specific slicer and hardware settings to change.

Real output. Not vibes.
Every diagnosis names the exact slicer setting and a target value, ranks the fixes by priority, and tells you what to watch on the next print. No “it could be a lot of things.”
- →Exact settings, exact values. “Bed Temperature → 100°C,” not “try a higher temp.”
- →Confidence you can read. A 10-segment meter, so you know how sure it is.
- →Built for engineering filaments. PA, CF blends, ASA, PETG — not just PLA.
Heavy stringing and blobs between parts: the PETG is oozing during travel moves because retraction is too low for a Bowden setup and the nozzle is running hotter than this filament needs.
Fixes
Increase retraction distance
highRetraction Distance → 5 mm
Lower the nozzle temperature in 5°C steps
highNozzle Temperature → 235°C
Avoid crossing perimeters on travel moves
mediumAvoid crossing walls → On
Add a small Z-hop so the nozzle stops dragging through blobs
lowZ Hop When Retracted → 0.2 mm
Watch for next time
Clean travel moves with no fine strings between the towers. If strings persist, raise retraction to 6 mm before touching temperature again.
