Uneven quality print over height
Hello,
I just start to experiment printing with a brand new SL1S, and I'm facing an issue I do not manage to solve.
The quality is not even over the printing cycle : first third it is bad, next third it is ok, and the remaining part is so-so.
It is not a calibration issue as the test models print well.
Same issue with Prusa Tough Orange and Anthracite grey.
Same issue whatever exposure time I set (from 1.6 to 2,4).
Same issue whatever orientation the model is (straight or inclined), with or without support.
I pre-head the resin, the FEP is new and clean, and the resin is fresh.
What is surprising is the the quality seems to be linked to the shape the model: the last part (that is no that good) starts exactly at the bottom of the "window" of the model...
If someone has any clue, I would really appreciate.
This is the model:
This is the print result:
