Is a CNC router ever appropriate for an elementary makerspace?
Our position, and the 'technology-forward' counterpoint.
Our position
K-5 does not need a CNC. The tool is too dangerous, the learning curve is too steep for the pedagogical value, and a Cricut + small laser + 3D printer triad covers the same design-to-physical-object pipeline with dramatically less risk. A principal thinking 'our CTE-aligned tour would look better with a CNC' is thinking about the tour, not the students. Skip it until middle school.

Reputable sources worth reading before you decide. Labels reflect our honest read of each source's general stance, not direct quotes.
Carbide 3D target-age documentation
Broadly agreesCarbide 3D's published curriculum targets middle school and up, not K-5. The manufacturer itself does not recommend it for elementary.
FIRST LEGO League / robotics pedagogy
Broadly agreesElementary-age robotics programs explicitly avoid CNC. The pedagogical model is 'build with kits first, machine your own parts later.'
STEM-showcase advocates
Pushes backSome administrators want CNC visible in elementary as a tour-driving feature. Defensible for the facility pitch; not for the pedagogy.
