I'm using the following settings:-
primary layer height 0.15mm
First layer height 120%
top layers 3
base layers 1
When I prepare print in S3D, I notice the first layer height is 0.9mm!! this is 600% of primary layer height - where did this come from? (shouldn't this be 0.15x120% = 0.18mm?) I noticed this after I tried printing something in ABS and the bead barely touched this build plate and eventually stopped extruding as it overloaded the extruder and ground the filament to a halt.
The next x3 layers are 0.333mm (this is 222% of the primary layer height - again where did this come?)
The first layer above the raft is 0.15mm as expected.
Is there some setting that I don't know about (I'm a relatively new user) which affects the raft height layers?
Thanks in advance,
