1. Poor Bed Adhesion
Symptoms:
First layer doesn’t stick well
Filament detaches during printing
Common Causes:
Bed not properly leveled
Inadequate bed temperature
Dirty or worn bed surface
Incorrect Z-offset distance
Solutions:
Level bed using paper as a reference
Adjust bed temperature based on material
Clean the surface with isopropyl alcohol
Correct Z-offset in slicer or firmware
2. 
Filament Tangles
Symptoms:
Filament stops mid-print
Clicking sounds from extruder
Common Causes:
Poorly wound spool
Excessive extruder tension
Low-quality filament
Solutions:
Check proper spool mounting
Adjust extruder tension as per specs
Use high-quality filament (like GST 3D)
3. 
Incorrect Printing Temperatures
Symptoms:
Poor layer bonding
Filament over- or under-melting
Solutions:
Adjust temperature according to material:
4. 
Warping (Part Deformation)
Symptoms:
Lifted corners
Curved base
Common Causes:
Thermal contraction
Poor bed adhesion
Air drafts
Solutions:
Use heated bed appropriately
Apply adhesives (hairspray, tape, glue stick)
Enclose print area or avoid drafts
Add brim or raft in slicer
5. Nozzle Clogs
Symptoms:
No filament extrusion
Clicking from extruder
Common Causes:
Debris in the nozzle
Contaminated filament
Wrong temperature
Solutions:
Perform a cold pull
Replace nozzle if needed
Set correct nozzle temperature
6. 
Stringing (Unwanted Threads)
Symptoms:
Fine threads between printed parts
Common Causes:
Nozzle temperature too high
Improper retraction settings
Solutions:
Lower nozzle temperature in 5°C steps
Adjust retraction distance and speed in slicer
7. 
Layer Shifting
Symptoms:
Misaligned layers
Common Causes:
Loose belts
Dirty or dry axes
Too high print speed
Solutions:
Tighten belts
Clean and lubricate rails and bearings
Reduce print speed
8. 
Under-Extrusion
Symptoms:
Gaps or missing material in layers
Thin or incomplete parts
Common Causes:
Partial nozzle clog
Inconsistent filament diameter
Incorrect flow rate settings
Solutions:
Clean or replace nozzle
Use quality filament with strict tolerances
Increase extrusion flow in slicer gradually
9. 
Part Overheating
Symptoms:
Warped or melted upper layers
Loss of detail
Common Causes:
Too high nozzle temperature
Low print speed
Poor cooling
Solutions:
Lower nozzle temperature
Increase print speed
Improve cooling using fans or slicer settings
10. 
Cooling Issues
Symptoms:
Poor bridge and overhang quality
Common Causes:
Faulty or misplaced cooling fans
Inadequate slicer fan settings
Solutions:
Verify fan placement and function
Optimize cooling speed in slicer
General Printing Tips
Always use dry filament
Clean the nozzle and extruder regularly
Use reliable slicers: Cura, PrusaSlicer, OrcaSlicer
Save verified profiles from GST 3D
Update firmware when needed
