| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Entry model of the 3-series. Unlike the X-Plus 3 and X-Max 3 it has no heated chamber, a 300 °C rather than 350 °C hotend, a brass rather than copper-alloy/hardened-steel nozzle head, and no Ethernet. It shares the Cortex-A53 board with them, so control-board specs must not be read as shared print specs | 3 sources
