How to solve the sticking issue?

Sticking issues in 3D printing are common, but they can be easily resolved with a few simple steps. Here are some things you can try to solve the sticking issue:

1. Adjust the bed level: If the bed is not level, the extruder nozzle may be too close or too far away from the bed, causing the filament to either stick too much or not stick at all. Use the printer's bed leveling feature to adjust the bed level.

2. Clean the bed surface: Dust, grease, or other debris on the bed surface can prevent the filament from sticking properly. Clean the bed surface with rubbing alcohol or soapy water before each print.

3. Use a different bed surface: Some filaments may stick better to a different bed surface. For example, ABS may stick better to a heated glass bed, while PLA may stick better to a blue painter's tape.

4. Use a different adhesive: If the filament is still not sticking, try using a different adhesive, such as hairspray or glue stick.

5. Adjust the printing temperature: If the filament is not sticking well, try increasing the printing temperature slightly.

6. Slow down the printing speed: Printing too fast can cause the filament to not stick properly. Try reducing the printing speed to give the filament more time to adhere to the bed.

By trying these steps, you should be able to solve the sticking issue when 3D printing.
