Troubleshooting

This section describes common printing issues, their causes, and recommended solutions.

Print Not Sticking to Build Plate

Symptoms

• Model detaches during the first layers

• Filament does not adhere to the surface

• Edges lift or warp

Possible Causes

• Contaminated build plate (oil, dust)

• Bed temperature too low

• Incorrect first layer height

• Improper material settings

Solutions

1. Clean the build plate

   • Use isopropyl alcohol or a lint-free cloth

   • Avoid touching the surface after cleaning

2. Increase bed temperature

   • For PLA: 50–60°C recommended

3. Adjust first layer height

   • Ensure slight filament compression

   • Adjust Z-offset if necessary

4. Use default settings

   • Avoid manual tuning during initial prints

Note

If adhesion fails in the first layer, stop the print immediately and correct the issue.

Stringing (Unwanted Filament Threads)

Symptoms

• Thin strings between printed parts

• Rough or “hairy” surface appearance

Possible Causes

• Nozzle temperature too high

• Retraction settings not optimized

• Moist filament

Solutions

1. Reduce nozzle temperature

   • Lower in 5–10°C increments

2. Enable or adjust retraction

   • Use default settings if unsure

3. Dry the filament

   • Store in a dry environment

   • Use a filament dryer if available

Note

Stringing typically affects appearance only and may not impact functionality.

Print Stops Midway

Symptoms

• Print pauses unexpectedly

• Printer becomes idle before completion

• Incomplete model

Possible Causes

• Filament runout or tangling

• Network interruption

• Software or job error

Solutions

1. Check filament supply

   • Ensure sufficient filament

   • Confirm no tangling

2. Resume the print (if supported)

3. Restart the print job

   • Use a stable connection

4. Verify network stability

   • Avoid interruptions during printing

Note

For long prints, confirm filament availability before starting.
