Quick diagnosis
Understand which calibration tools are useful for FDM printers and what each one actually helps measure.
Likely causes
- Guessing measurements
- Frame not square
- No real measurement baseline
- Changing too many settings at once
Step-by-step fix
- Use calipers to measure test prints.
- Use feeler gauges for mechanical reference.
- Use a square to check frame alignment.
- Use test models to verify results.
What to check before changing more settings
Only change one variable at a time. Save your current slicer profile before testing, use a small repeatable test print, and compare the result before moving to the next adjustment.
