Filaments not recommended for the AMS lite, and why

Bambu advises against TPU 95A or softer, TPE, absorbent PVA, and most CF/GF filaments in the AMS lite; it lists Bambu PLA-CF and Bambu PETG-CF as exceptions. (source) Bambu states the AMS has an extra transmission gear that the AMS lite lacks, so PETG-CF and PLA Wood are compatible with the AMS but not recommended for the AMS lite. (source)

For TPU specifically, Bambu's AMS lite FAQ lists hardness 77D, 55D or higher[src] as usable and 95A, 85A, 83A, 80A or lower[src] as not usable.

Categories Bambu does not rate "Compatible" for the AMS lite

Category assignment is automatic, from the product's database material and name (e.g. names containing CF/GF are treated as fiber-filled). See methodology.
