Machine Operation (Cont.)
Symptom Possible Cause Possible Solution
"Stringing" occurs,
e.g. strands of
filament hang off
object. 1. Insufficient retraction.
2. Temperature too hot for type of filament. 1. In slicer software, turn on or increase retraction.
2. Lower temperature and restart preheating process
(
Page 26). Lower temperature may require slower
print speed.
"Warping" occurs,
e.g. edges of object
separate from build
platform. 1. Insufficient adhesive.
2. Build plate not level. 1. Clean build plate, then re-apply adhesive ( Page 26).
2. Level build plate (
Page 24).
Layers are
misaligned or
object skews in one
direction. 1. Belts slipping/pulleys misaligned.
2. Drive sprockets slipping on shaft.
3. Z-axis leadscrew dirty.
4. Bent or misaligned axis rods or leadscrew.
1. Tension/replace belt(s); ensure pulleys are aligned
(
Page 44).
2. Tighten/replace loose drive sprockets.
3. Clean and lubricate leadscrew (
Page 33).
4. Test/repair/replace.
Occasional layer is
missing. 1. Z-axis leadscrew dirty.
2. Bent or misaligned axis rods or leadscrew. 1. Clean and lubricate leadscrew (
Page 33).
2. Test/repair/replace.
Fine detail does not
print. 1. Print resolution too low.
2. Build plate not level.
3. Nozzle diameter too large for object details.
4. Nozzle clogged.
5. Print speed too fast for type of filament.
1. In slicer software, increase resolution by decreasing
layer height.
2. Level build plate (
Page 24).
3. Replace with smaller nozzle ( Page 41).
4. Clean (
Page 37) or replace (Page 41) nozzle.
5. In slicer software, reduce print speed.
Feed motor grinds
or skips. 1. Feeder tension too high.
2. Nozzle clogged.
1. Remove filament from feeder, clean ground filament
from hobbed gear and Bowden tube, then lower
feeder tension.
2. Clean ( Page 37) or replace (Page 41) nozzle.
