Run PDCA on a Print Profile
Use a PDCA cycle to improve a print profile with controlled changes and measurable evidence.
Improve a PETG bracket profile with stringing and rough holes without losing track of what caused the improvement. Plan -> Do -> Check -> Act The common trap is slicer whack-a-mole: changing many settings at once, getting a better print, and learning nothing repeatable. Plan Target one defect: stringing between bracket posts. Hypothesis: nozzle temperature is too high. Metric: cleanup minutes and visual stringing on the same test geometry. The plan names a defect, a cause hypothesis, and how success will be judged before touching settings. Do Run one test at 235C while holding speed, fan, retraction, filament, and geometry…
