settings are not optimized.
Obstructions in the optical path
block the laser from curing resin
in a specific part of the model.
Solution
Consider the following:
• Check the resin tank for debris
or damage.
• Check the model in PreForm.
• Check cleanliness of optical surfaces.
Use the X/Y Fine Tuning tool to
correct any consistent discrepancies
in measurement between the model's
design and printed results. The X-axis
refers to the left-to-right direction on the
build platform. The Y-axis refers to the
front-to-back direction.
Consider the following:
• Check the underside of the resin tank
for debris or damage.
• Check cleanliness of optical surfaces.
