Nozzle and layer

This checks a geometric relationship, not whether a profile is safe for every printer. Use a tested slicer profile for your exact machine, nozzle, and material.

Layer-height reference

Prusa recommends keeping layer height below 80% of nozzle diameter and notes that it cannot exceed nozzle diameter.

Sources & use notes

Use manufacturer settings as tested starting points. Confirm them with your exact machine, material, and supplier instructions before production.
