First layer height - more discrepancies

[reddadsteve]

I'm aware of the changes to the first layer height and the ongoing discussions about the recent changes related to using the z-offset for first layer squish. However this post is yet another issue regarding first layer height.

When no raft is used, a value over 100 results in how the first layer is sliced, not just how much extra filament is used. So a first layer height of 200% on a model with a .1mm layer height is actually one layer less. The final height is the same but one fewer layers. The first layer is sliced and printed at .2mm

When a raft is used, a value over 100 results in the first raft layer (already quite thick on purpose) printing at a thicker size but no change to the rest of the raft or slicing of the model.

This discrepancy may sound nit-picking, but due to the way I model miniatures for release to the general public it definitely results in a lot of confusion.

S3D support, If nothing else, better documentation would go a long way to helping your customers with this product.

There's more than just referring to better documentation...….there's the difference between technical documentation and user documentation. In other words the context of what is said.

An example.... lets pretend we're looking at a picture of the bed of a 3D printer....and we mention "The first layer". Hold that thought!

Now let's look at a picture of a 3D printed part....and we mention "the first layer". Hold that as a second thought.

Compare those two thoughts....are they exactly the same? To a technical person, the "first layer" will be the first layer extruded onto the bed....which may not be the first layer of the part. But for a non-technical person.....a user....the "first layer" will always be the first layer of the part.

Here we have by far the biggest problem with software documentation.....its written by technical people (ie developers) and intended to be used by non-technical people ( ie users). And the second biggest problem is the documentation deliberately written by technical people for the non-technical people....the author assumes all the users are idiots and says "Do that" without explaining what "Do that" actually does...which is useless for anyone wanting to improve their technical knowledge of the product.
