Model G0923 (Mfd. Since 05/20)
-35-
Machine Operation (Cont.)
Symptom
Possible Cause
Possible Solution
Molten filament runs
freely from nozzle.
1. Temperature too hot for type of filament.
1. Lower temperature and restart preheating process
(
Page 26). Lower temperature may require slower
print speed.
Printing stops in
middle of job.
1. Insufficient filament.
2. Nozzle clogged.
3. Feeder tension too low.
4. Feeder tension too high.
5. SD card at fault.
6. SD card reader at fault.
1. Replace filament (
Page 29).
2. Clean (
Page 37) or replace (Page 41) nozzle.
3. Tighten feeder tension (
Page 4).
4. Remove filament from hobbed gear, clean ground
filament from feeder and Bowden tube, then lower
feeder tension.
5. Use different SD card.
6. Test/repair/replace.
Nozzle catches on
print object.
1. Build plate not level.
2. Incorrect print speed for type of filament.
1. Level build plate (
Page 24).
2. In slicer software, select print speed settings
appropriate for type of filament.
"Under extrusion"
occurs, e.g. object
prints with very thin
or missing layers.
1. Incorrect temperature for type of filament.
2. Filament tangled on spool.
3. Filament stored in humid environment.
4. Nozzle too close to or too far from build
plate.
5. Incorrect print speed for type of filament.
6. Feeder tension too low.
7. Feeder tension too high.
8. Nozzle clogged.
9. Nozzle loose in heater cartridge or stripped
threads.
10. Heating block at fault.
1. Adjust temperature and restart preheating process
(
Page 26). Lower temperature may require slower
print speed.
2. Unwind filament from spool until it is not tangled or
overlapping.
3. Replace filament (
Page 29).
4. Level build plate (
Page 24).
5. In slicer software, select print speed settings
appropriate for type of filament.
6. Tighten feeder tension (
Page 4).
7. Remove filament from hobbed gear, clean ground
filament from feeder and Bowden tube (
Page 43),
then lower feeder tension (
Page 4).
8. Clean (
Page 37) or replace (Page 41) nozzle.
9. Replace nozzle and/or heating block.
10. Test/repair/replace.
"Over extrusion"
occurs, e.g. object
prints with thick
layers that have
drips, strings, or
blobs.
1. Incorrect temperature for type of filament.
2. Filament setting incorrect.
3. Incorrect extrusion multiplier selected.
4. Flow setting too high.
5. Heating block at fault.
1. Adjust temperature and restart preheating process
(
Page 26). Lower temperature may require slower
print speed.
2. In slicer software, select correct filament type.
3. In slicer software, select correct extrusion multiplier.
4. In slicer software, decrease flow setting.
5. Test/repair/replace.
"Pillowing" occurs,
e.g. top layer is poor
quality with bubbles
and gaps across its
surface.
1. Top layer too thin.
2. Cooling fans at fault.
3. Temperature too hot for type of filament.
1. In slicer software, increase top/bottom layer
settings.
2. Test/repair/replace.
3. Lower temperature and restart preheating process
(
Page 26). Lower temperature may require slower
print speed.
