↗ MAINTENANCE AND REPAIR
Keep your printer reliable.
Most printing problems have simple causes. With regular care and knowing where to look, you will print cleanly again.
It worked yesterday,
not today.
The first layer won't stick, the nozzle is clogged or the layers shift. Without a system you look in the wrong place and replace parts that aren't faulty at all.
Maintenance plan
| Interval | What to do |
|---|---|
| Regularly | Clean the build plate (depending on the plate with washing-up liquid and water or isopropyl alcohol), remove filament residue from the nozzle, check the spool and filament path for knots and dust. |
| Monthly | Clean the guides and lubricate them as the manufacturer specifies, check belt tension, clear dust from fans and cooling ducts, tighten screws, keep firmware and slicer profiles up to date. |
| Yearly or as needed | Check and replace the nozzle and wear parts such as the PTFE tube or extruder gears, replace a worn build plate, redo the full calibration. |
The intervals depend on how much you print and on your machine. Always follow the manufacturer’s instructions.
Common print defects
| Defect | Possible causes | First steps |
|---|---|---|
| Poor adhesion | Dirty build plate, wrong distance between nozzle and bed, bed too cold, draughts | Clean the plate, check the Z offset and levelling, adjust the bed temperature, use a brim or an enclosure. |
| Stringing | Wet filament, temperature too high, retraction not set right | Dry the filament, lower the temperature in small steps, adjust retraction. |
| Clogged nozzle | Burnt residue, foreign particles, heat rising too far up (heat creep) | Do a cold pull, clean or replace the nozzle, check the hotend cooling. |
| Layer shift | Loose belts or pulleys, nozzle hitting curled-up parts, acceleration too high | Check belts and grub screws, reduce speed, prevent warping. |
| Under-extrusion | Partly clogged nozzle, dirty or worn extruder gear, temperature too low, speed too high | Check and clean the filament path and extruder, calibrate the flow, adjust temperature or speed. |
