One good sheet does not prove that your setup is stable.
Watch for these three warning signs:
1. The pressure pattern changes from sheet to sheet.
2. The patching area keeps growing.
3. The result changes after a speed change.
If the result keeps moving, stop correcting the symptom.
Check the reference first.
A stable setup repeats throughout the run.
