I've gone from a 0.5mm nozzle to a 0.3mm.Haven't tried a print yet with the new nozzle.

Which software/firmware setting(s) do I need to change?

Thanks in advance.

you should only need to change it in slic3r or whatever.
since extrusion steps is done on filament input rather than output.

But remember to measure the output filament: you need to put in the software the actual width of extruded filament and not the size of the nozzle (ie: my 0.5mm nozzle is giving me a 0.7mm extruded ABS filament).

psht, use slic3r it works it out automaticaly.

If using Skeinforge, the main settings you'll need to change are:

Carve: Edge width over height (1.5), layer thickness (0.3) instead of 0.4 for the 0.5mm nozzle.
Inset: Infill width over thickness (1.5)

these should improve your print quality significantly but I found that I had to calibrate other settings to get the best out of the change.
