Part 7 - Common Issues

Even with a high-quality printer like the Bambu Labs P1P, you'll eventually run into printing issues. Most problems fall into a few categories: bed adhesion failures, nozzle clogs, and spaghetti failures. Fortunately, these are easy to fix once you understand their causes and solutions.

Even with a high-quality printer like the Bambu Labs P1P, you'll eventually run into printing issues. Most problems fall into a few categories: bed adhesion failures, nozzle clogs, and spaghetti failures. Fortunately, these are easy to fix once you understand their causes and solutions.

Bed Adhesion Issues

The most common problem in 3D printing is poor first-layer adhesion, where prints don't stick properly to the build plate. This can cause warping, peeling, or complete detachment, leading to failed prints. The simplest fix is to clean the bed using isopropyl alcohol and a paper towel to remove dust and oils. Occasionally, washing the plate with hot water and dish soap can help restore adhesion.

Another solution is using brims, which create a wider base to help small or narrow prints stay attached. If adhesion problems persist, consider using glue designed for 3D printing or replacing a worn-out build plate. Over time, repeated prints can wear down the textured surface, making it harder for filament to stick properly.

Nozzle Clogs

A clogged nozzle can lead to under-extrusion, weak prints, or no filament coming out at all. This is often caused by low-quality filament, dust buildup, or using filament that has absorbed moisture. The first step in fixing a clog is to heat the nozzle to 220-230°C and try pushing out any stuck filament with an Allen key.
