Perform Nozzle Cold Pull and Cleaning

To resolve partial clogs causing extrusion failure at high-detail layers, follow these steps:

1. Heat the nozzle to 220°C and use the provided cleaning needle to clear the tip.
2. Perform a 'cold pull' by heating the nozzle to 250°C, inserting cleaning filament (or PLA), cooling it to 90°C, and pulling it out quickly to remove internal debris.
3. Verify success by performing a manual extrusion test via the printer screen to ensure the flow is consistent and straight.
