I have a Prusa-type filament printer (Geeetech).
I have been experimenting with the clearance between nozzle and bed and have found that a smaller clearance produces a better adhesion brim. It seems to stick more securely to the glass plate and, being thinner, is easier to remove.
The problem is that the Initial Layer Height in Cura is set to 0.3mm, which means my models are slightly shorter in the Z-dimension than they should be. I can set this to, say, 0.1mm (Custom Settings) but I have a question. Does this just affect the slicing calculation (i.e. more layers), or does it also affect the extrusion rate for the initial layer and/or the Z height of subsequent layers?
Thanks,
Julian
