Cause:

• Cause #1:

Heater heating cycles of the heater causing the resin the shrink and expand during the print, making uneven surfaces.

• Cause #2:

The orientation of the print combined with not enough supports is not Ideal.

Solution:

• Option#1:

test run with turning off the heater will confirm the cause, the problem happens usually with users live in cold-weather regions, better heat-loss protection for the Moai will most likely fix the problem (this is based on user’s result).

• Option #2:

Make sure the densest part of the model is on the build plate facing towards the red, put model at 45-degree angle towards the green side of the plate in asura.

Make sure there are ample supports to hold the structure of the part during the riggers of printing.

Cause: dust/slicer/small debris

Solution:

1. Dust: Check for dust on the galvo mirror, acrylic protector or vat bottom. Clean very carefully.
2. Slicer: Make sure you are using up to date slicer. Double-check your gcode/model export from design program.
3. Small debris: filter resin/clean vat.
