- First layer not sticking: causes and checks
How to recognise a first layer that is too high, too squished or uneven and fix it in order: plate cleaning, slicer profile, leveling, Z offset. Based on official guidance from Bambu Lab, Prusa, Creality, Elegoo and Anycubic.
- Warping: corners lifting off the bed with ABS, ASA, PETG and PLA
Why corners curl and how to reduce it: plate cleaning, drafts, enclosure, bed temperature, brim and ears, cooling and glue. Based on official guidance from Bambu Lab and Prusa and on user experience.
- Clogged nozzle and under-extrusion: find where the blockage is and fix it
How to tell a blockage in the PTFE tube, the extruder or the hotend apart, when to use the needle and cold pull, how to recognise heat creep, and when replacing the nozzle, PTFE tube or gears is actually justified.
- Wet filament: recognise it, dry it and store it
Symptoms of filament that has absorbed moisture, the most sensitive materials, how to dry following Bambu Lab and Prusa official tables without damaging spool or filament, and how to keep it dry.
- Stringing and oozing: how to get rid of filament strings and blobs
How to recognise stringing and oozing, the main causes (wet filament, temperature, retraction, travel moves, nozzle) and the checks to do in order, with official guidance from Prusa, Bambu Lab, Creality and Elegoo.
- Layer shifting: causes and checks in order
Why layers shift along X or Y and how to find the cause: obstructions, collisions with curled parts, belts, pulleys, speed, electronics cooling and motors, with official guidance from Prusa, Bambu Lab, Creality, Elegoo and Anycubic.
- Ringing and ghosting: getting rid of ripples on FDM print walls
What ringing (or ghosting) is, why it appears after corners and lettering, and how to fix it in order: printer surface, loose parts, belts, lubrication, vibration calibration (input shaping), speed and acceleration.
