I'm printing the Ameralabs calibration piece (small high resolution test piece)
If I slice with default settings for my Elegoo Saturn on 1.9.0 I get a loss of resolution and a noticable increase in the Y axis only, as if the Y axis voxels were doubled.
The same piece sliced with 1.8.1 prints perfectly
(pictures to follow)
Left is sliced with 1.9.0 - notice how the finer pins are oval shaped and gaps between blocks have been filled
Right is sliced with 1.8.1
