Best advice I can give. We run a 3-layer shell, and if the first three layers come out, we're good until much later in the build unless something goes badly wrong like a jammed tip. If the first three don't come out, we'll stop and tune.

Protip: find a small, 10-15 minute build. Maybe something you can do as a giveaway. If you make a machine settings change, or a machine change, run one and see if it turns out right. We use turtles.
