This is from a beta thread, don’t know if you can read it or not, but I’ll put the reply Oz posted there just in case you have problems with the beta link.
With 3D Slice, each pass is thresholded to the current threshold value, and the result is run as a 1-bit image. If you use 256 passes you get exactly one pass per gray-level in the image. Every pixel at or below brightness 255 for the first pass, every pixel at or below 254, then 253, and so on.
If you choose 128 passes, you get every pixel at or below 254 for the first pass, then 252, then …
It “clusters” the layers together into batches if you use fewer than 256 passes, and will duplicate some layers (with even spacing) if you use more than 256. 384 passes would duplicate every 2nd layer. 512 passes would duplicate every layer.
Here are a couple of suggestions on it’s use. These use 256 passes and took about an hour and a half to 2 hours to run each. I think @Bulldog and I have very similar M60 MOPA machines.
More of an oblique angle…
Hope this helps clarify 3dslice operations. I think we’re all learning these operations.
Good luck
