We want every Expert Extrusion guide to be right. Filament brands change. Printer firmware changes. Sometimes we just miss a number.
How to report an error
Email connect@expertextrusion.com (see Contact). Tell us:
- Which guide you mean.
- What looks wrong.
- How we can check it, such as a measured figure, a profile file, or a link.
What happens next
We check what you sent against our sources. If the guide is wrong, we update it.
Editing errors—typos and small slips—get fixed quietly, with no note on the page.
When a guide materially changes after we publish, for example when something new happens, we add a short note that says what changed and cites the source that shows it happened after publication. That should be rare.
