Dragon ACE Volcano PT1000
The Trianglelab Dragon ACE with PT1000 is a high-flow hotend for 1.75 mm filament. Its rigid structure combines a nickel-plated copper block, a titanium-alloy heatbreak, a copper heatsink and a replaceable flat 24 V ceramic heater. This variant includes a 3 mm encapsulated PT1000 sensor.
It accepts short V6-style nozzles and allows the nozzle to be changed while the hotend is held correctly, without a freely rotating heater block. This is the standard short-block Dragon ACE; Dragon ACE Volcano variants use a longer block and a different cylindrical heater cartridge.
Construction and specifications
The titanium heatbreak separates the cold and hot zones. Four insulating zirconia columns help limit heat transfer to the body, while the heatsink requires sufficient airflow during printing. The block coating protects its surface and makes cleaning easier.

| Rigid mounting | Four 4 mm deep M2.5 threads on a 16 mm pattern |
Identifying the PT1000
The PT1000 is a resistive RTD with a nominal resistance of 1000 Ω at 0 °C. It is not a 100 kΩ NTC thermistor and must not be configured as a 104NT-4 or Beta 3950. Other sensors sharing the 3 mm cartridge diameter are not automatically electrically interchangeable.
The controller input must support a directly connected PT1000 or use a suitable interface. Check its circuit and actual pull-up resistor before choosing a configuration. A MAX31865 module, for example, requires different wiring and settings from a PT1000 connected directly to an analogue input.
Initial Marlin and Klipper configuration
| Firmware | Board-dependent setting |
|---|---|
| Marlin | For the first hotend, use TEMP_SENSOR_0 1047 with a 4.7 kΩ pull-up; 1022 with 2.2 kΩ or 1010 with 1 kΩ. Verify the actual input and Marlin version before compiling. |
| Klipper | With a suitable analogue input, use sensor_type: PT1000 and the real sensor_pin. pullup_resistor defaults to 4700 Ω; change it if the controller schematic specifies another value. |
Before enabling the heater, the cold reading must be stable and consistent with ambient temperature. Keep thermal protection enabled and set the maximum temperature according to the most restrictive component in the installation, with sufficient margin. Do not copy the temperature limit from a version with a different sensor.
Ceramic heater and revision-dependent power
Trianglelab has documented revisions of its 24 V ceramic element with different power ratings. The newer documentation specifies 105 W nominal, equivalent to approximately 4.4 A at 24 V as a sizing reference; earlier documentation lists 82 W. Before powering a specific unit, identify its revision and make sure the supply, MOSFET output, connectors and wiring can handle its current with margin. PWM limiting does not make an undersized connector safe against peak current.
If your unit is the current 105 W revision, the Trianglelab 24 V, 105 W Dragon ACE ceramic element may be used as a spare by following the manufacturer's fitting procedure. Check physical fit, electrical revision and clip engagement. The 70 W cylindrical cartridge used in Volcano versions does not fit this block.
Mounting on your printer
The body mounts directly through four M2.5 threads on a 16 mm pattern. Solutions also exist with a 3 mm spacer to recover the position of some original Dragon mounts and with V6 Groove Mount adapters. Confirm which support and accessories your particular toolhead requires.
The Dragon ACE hot section is approximately 8.5 mm longer than the original Dragon's. Even if the mount fits, nozzle position, part-cooling fan, probe and Z offset may change. On Voron, Prusa, RatRig, Ender, HPRO and other printers, compatibility depends on toolhead, revision, cooling, electronics and wiring, not on the printer model alone.
Nozzle, flow and maintenance
Use V6-style nozzles for 1.75 mm filament, with an M6 × 1 thread and 7.5 mm threaded length. The 0.4 mm Trianglelab T-V6 nozzle matches this geometry; choose a wear-resistant nozzle material as well for abrasive filaments. Do not substitute a long Volcano, MK8 or Revo nozzle merely because its nominal thread diameter matches.
If you need a longer melt zone, the Trianglelab MZE HF Plus extender is a separate accessory. Trianglelab publishes up to 74 mm³/s in a test with MZE, PETG and a 1.2 mm nozzle; that result does not describe the standard hotend without the extender. Calibrate actual volumetric flow for your filament, temperature, nozzle and required quality.
The nozzle seals internally against the corresponding hot-side part. Hot-tighten it and check for leaks after the first print; Trianglelab states a maximum of 2 N·m, and any lower nozzle limit takes precedence. The PT1000 retaining screw should only hold the cartridge gently, without crushing it. After changing the sensor, heater or nozzle, check the cold reading and retune PID.
It is for you if
- You want a compact Dragon ACE with V6 nozzles and a PT1000 sensor.
- Your controller has a suitable PT1000 input or compatible interface.
- You can verify the mount, cooling, heater current and final calibration.
It is not for you if
- Your board supports only an NTC thermistor configuration and you cannot adapt the electronics.
- You require a long Volcano block or cylindrical heater cartridge.
- You need a direct replacement without checking nozzle, mount, probe and Z height.
