Splinter here. Let’s take a methodical look. First, feel the bed. Is it level? Use a piece of paper between the nozzle and the bed; you should feel a slight resistance. If it’s uneven, level the bed or adjust the screws until the paper slides easily. Next, check the first‑layer height. If the nozzle is too high, the filament won’t stick. Lower the Z‑offset a little so the first layer is slightly squished into the bed. Once the layer prints cleanly, you can fine‑tune the offset. Now consider the temperature. 200 °C is fine for many filaments, but if your nozzle or hot‑end has a hot‑spot or the ambient temperature is low, you might need a bit higher. Raise it in 5 °C increments and watch the first layer. The filament should flow smoothly and adhere. Check the filament itself. Is it dry? Moist filament can pop and cause bubbles. If it feels brittle, dry it in an oven or a filament dryer. Also, feel the filament for any knots or inconsistencies. If you find any, feed it through the extruder a bit more to let the hot‑end clear it. Make sure the extrusion multiplier or flow rate is correct. Too low and you’ll see gaps; too high and you’ll get over‑extrusion and popping. Try a calibration print—an extrusion test or a simple cube—to confirm the flow is within ±5 %. Finally, examine the extrusion feed. Is the filament feeding steadily? If you hear a click or a sudden stop, check the drive gear for debris or wear. Clean or replace if necessary. Take one step at a time, verify the result, and you’ll have a smooth print. Remember, a calm mind and a methodical approach will catch the issue before it spirals.
