Hotend Heater + PT1000 Kit — Runice 24V 70W + PT1000 Sensor

For 300°C-plus: Runice's 70W cartridge with a PT1000 RTD sensor. The pairing high-temperature toolheads are built around — the heavily insulated 70W made for dfh.fm and a platinum sensor rated to 450°C.

What's in the kit

• 1× Runice 24V 70W high-temperature heater cartridge — 6 × 20 mm, 1 m red fiberglass-sleeved leads, tinned ends (P/N 3028-07A)
• 1× PT1000 temperature sensor — 2-wire RTD, 3 × 15 mm stainless probe, 1 m lead, −40 to 450°C

Fits

• Boards and firmware set up for PT1000 — direct input with the right pull-up on most 32-bit boards, or through a MAX31865 — with a 6 mm cartridge bore and a 3 mm sensor bore.
• Engineering filaments: PA-CF/GF, PET-CF, PEI-class materials that a 100K NTC does not read well past 300°C.

Gotchas

• 24V only. 2.9 A needs a real connector for the heater (Micro-Fit 3.0 or screw terminals). Configure the PT1000 before the first heat-up — a thermistor table will read wildly wrong — then PID tune.
• 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.
