I tried to search the forum for my question below, but failed to find it - my apologies if I ask something that has been answered xx times already.
I come from a Repetier / Cura slicer environment & S3D is quite new to me. I recently ran into something that I am probably misunderstanding: hope you can point me to the right direction.
In a printer's profile file in S3D, we have the opportunity to create multiple print quality settings - this is connected, among other parameters, to layer thickness.
The profile has a Primary Layer Height field & then allows modifications to the first layer settings by providing percentage adder fields, such as "First Layer Height" (in %).
Here's the thing, that's puzzling me:
If I create a "fast" layer for - say - 0,30 mm layer thickness, the modification factor for First Layer Height can be 100%. A thickness of 0.30 for a first layer is fine for me.
But if I then create a "fine" layer for - say - 0,10 mm layer thickness, I'd like to increase the modification factor for First Layer Height to something like 300%, meaning that I'd end up with a 1st layer of 0.30 mm for better adhesion.
But the First Layer height modification percentage applies overall, to all quality sets in the profile file. So, whether you'd select 0,10 (= "fine") or 0,30 mm (= "fast") 1st layer configuration - the modification factor for the first layer is in all cases the same value.
So, if I add First Layer Height = 300% for layer 0.10mm (fine) setting - I'd have my 0.30 mm 1st layer: that's perfect for me. However, if I then select 0.30 mm layer (fast) setting, I would end up with a first layer of 0.90 mm - which my 0.40 mm nozzle can't handle.
I'm probably looking at this in the wrong manner, right? Is there a way, I could have my 1st layer as 0.30 mm in all cases? Or is the idea to have a thicker 1st layer a thing of the past & can I leave that thought behind...?
