How It Works

The "magic number" is the smallest Z movement your printer can make accurately: lead_screw_pitch / (steps_per_rev x microstepping). Layer heights that are multiples of this number avoid Z-axis rounding errors, producing smoother surfaces. Max layer height should not exceed 75% of nozzle diameter.
