This guide is show you difference between 2023/2024 or 2025 version of K1 series hotend, as each version has slightly different design and connector, which will cause incompatibility if you purchased incorrect hotend/spares.

2024 vs 2025
The thermistor and heater connectors have been updated to the same ones used on the Ender 3 V3/V3 Plus. To differentiate, remove the connector—if it has a locking tab, you have the newer 2025 edition. Similarly, you can check your PCB breakout board. While the connectors differ, the silkscreen on the PCB remains the same, and it is cross-compatible; the only difference is the connector header.
