    "Dry first, then retraction. That order is the score-13 reply on r/FixMyPrint 1ix5trz. The score-4 reply on the same thread says the opposite and never dries PETG.",
    "A temperature tower is the tool named on r/prusa3d 11cxj6f, r/prusa3d 13ckz2q, and r/FixMyPrint 1qgm39r. Read the tower against the row you loaded.",

    "A score-4 reply says PETG never strings if retraction is right and that drying is irrelevant. That disagreement stays on the page.",
    "r/prusa3d 13ckz2q uses purefil at 230 °C (446 °F) on the first layer and an 85 °C (185 °F) bed. purefil is not a catalog brand, so those settings are not copied onto a ranked row."

  "community": "r/prusa3d 11cxj6f is a first PETG print on a Mini+ with stringing and pilling. The score-30 reply says drying, with no other change, is what made the prints clean. A score-5 reply ran a temperature tower, liked about 215 °C (419 °F), and says white and black eSUN PETG wanted different temperatures. The same reply still calls the poor surface humidity. r/prusa3d 13ckz2q is first-layer stringing and globs. The poster lists 230 °C (446 °F) on the first layer, an 85 °C (185 °F) bed, and purefil. The score-17 reply says PETG loves water and to dry it, then dial Z again. r/FixMyPrint 1qgm39r is Bambu PETG Translucent stringing on a simple hook. The score-46 reply calls some stringing a fact of life and names a temperature tower, retraction, and a lighter for leftover hairs. A reply says to dry for eight hours. r/prusa3d 11ykff2 is stringing on long prints. The score-26 reply says the main reason is wet filament. A score-11 reply says 230 °C (446 °F) looks low for Prusament and asks whether the nozzle is tight against the heatbreak. r/FixMyPrint 1ix5trz is heavy PETG stringing on an Ender 5 Plus. The score-13 reply says dry first, then tune retraction. A score-4 reply says they never dry PETG and that stringing is a retraction and temperature problem.",
