How it works

Z resolution is lead-screw travel per revolution divided by motor steps per revolution times microstepping. Each target height is rounded to the nearest whole step count and reported with its achievable value.

  • The target list covers common 0.1–0.3 mm profiles.
  • Hardware inputs determine the actual increment.

Worked example

A 1.8 degree motor on an 8mm lead screw
200 steps per revolution, 16x microstepping
Input
											Steps per revolution: 200
Microsteps: 16
Lead screw lead mm: 8
Output
												Z resolution mm: 0.0025
Recommended layer height mm: 0.2
Valid layer heights mm: 0.1, 0.12, 0.15, 0.16, 0.2, 0.24, 0.28, 0.3

When to use this

Printer builds, slicer profiles, and magic-number calibration prints check Z increments.

Edge cases

  • A height between step increments is rounded rather than exact.
  • Microstepping changes nominal resolution but not necessarily mechanical repeatability.
  • Backlash can dominate error even with fine arithmetic resolution.
