Regularly clean print cores
Optimize Z-strength
  • Wall thickness min. 2 mm, preferred 4 mm or more
  • Avoid strong external air circulation (ventilation, air conditioning)
  • Set “Fan Speed” and “Maximum Fan Speed” to 0% or 5% (note: reduces dimensional accuracy somewhat).
  • If printing multiple models single extrusion: set Cura setting “Print Sequence” to “One at a time”
  • Tip: avoid issues by orienting the model such that the highest mechanical forces are applied to the XY plane
