Troubleshooting

Oozing, Stringing

• Dry the filament properly
• Turn on “Avoid crossing perimeters”
• One object at a time (to avoid moving between objects)
  • So either one object, or sequential object printing.
• Experiment with temperature
  • Possibly use 240C instead of the default 255C.
• Simple Stringing Test

Layer Shifting

• Prusa - Layer Shifting
  • See Steph’s comment on the post. The “Avoid crossing perimeters” option might be the culprit.
