Hotend Heater + Thermistor Kit — Runice 24V 60W + 104NT Thermistor Cartridge

The high-speed CoreXY pairing: Runice's 60W high-temperature cartridge with its 104NT thermistor cartridge. The wattage Voron-class toolheads run so the block recovers between fast layers, and the spring-relieved, JST-XH-terminated sensor that goes with it.

What's in the kit

• 1× Runice 24V 60W high-temperature heater cartridge — 6 × 20 mm, 1 m lead, tinned ends (P/N 3028-03A)
• 1× Runice 104NT thermistor cartridge — 104GT-2 / 104NT-4-R025H42G class, spring strain relief, 1 m lead, JST-XH

Fits

• High-speed CoreXY and Voron toolheads — Dragon, Rapido-style and any block with a 6 mm cartridge bore and a 3 mm sensor bore.
• Klipper sensor type ATC Semitec 104NT-4-R025H42G; Marlin table 5. Need more? The 70W kit.

Gotchas

• 24V only. 2.5 A is at the top of a JST-XH's rating for the heater — use Micro-Fit 3.0, screw terminals or the toolhead board's heater terminals. PID tune after install.
• Heater block, connectors and silicone sock are not included.
• Same parts, same shelf as the singles linked above — if the kit reads sold out, one of its parts is.
