Under extrusion after retraction. - If it is retracting before a layer change and you have z seam underextrusion, that could mean that there's not enough filament after a retraction. It prints fine when there's only one part to the model, and as soon as the model goes to two or more sections (where the holes start) and it starts retracing between movements, the walls go very thin and weak and you can see light through them. ABS (Enclosure Recommended) Nozzle: 240–250°C Bed: 90 Feb 28, 2026 ยท PETG print settings: 230–250°C nozzle, 80–90°C bed, 30–50% fan. PETG Nozzle Temperature: 230–245°C Bed Temperature: 70–80°C Print Speed: 40–50 mm/s Retraction: 4–5 mm Cooling: 30–60% Reduce cooling to improve layer adhesion. To try and deal with the issue of under extrusion after a retraction and travel move you can try experimenting with increasing the retraction length and try adding a bit of extra prime on unretract. 025-0. 6-8mm of retraction and 0. I had my retraction set to 7mm which was the minimum amount to reduce stringing. You can also adjust your retraction speed: Retracting or detretracting too fast can cause the printer to skip steps, negating some of the retraction benefits and causing extrusion issues.
