Which hotend for a Voron 2.4: Stealthburner options

A Voron 2.4 takes any hotend that has a front part for its Stealthburner printhead, and nine hotend families have one in Voron’s own repository. Rated ceilings run from 300 °C (E3D Revo, Bambu Lab) to 500 °C hot blocks (Phaetus Dragon, Slice Engineering Mosquito). Changing hotend means printing a new front, setting the new sensor in Klipper and re-tuning the heater’s PID control loop.

Which hotends fit the Voron 2.4 Stealthburner toolhead?

The Voron Stealthburner toolhead on the Voron 2.4 has official printhead parts for nine hotend families: the Chube Compact, the E3D Revo Voron, Revo Six, Revo Micro and V6, and the Phaetus Dragon, Dragonfly BMO, Dragonfly BMS and Rapido. The Slice Engineering Mosquito, Dragon UHF, Rapido UHF and Bambu Lab X1/P1 hotend fit through vendor or community parts.

Voron’s printhead list names each hotend’s front part (the code in parentheses below) and its mounting screws. Rows are alphabetical by maker. Temperatures and flow figures are each maker’s own.

Makers test flow differently. E3D’s figures are for 0.4 mm nozzles at 0.2 mm layers with a Hemera XS extruder and a 60 W HeaterCore. Phaetus’s are for 1.0 mm nozzles on a Creality Ender-7, and Slice states no test on the Mosquito page. Compare figures within one maker’s range, not across rows.

Phaetus’s own store listed the Dragon ST and UHF, both Dragonflies and the Rapido 2 on October 30, 2026. The Dragon HF and the first-version Rapido were not listed.

Which Voron hotend upgrade fits what you print?

Temperature, flow and nozzle system decide between the options above, along with the parts each hotend replaces.

Temperature. The E3D Revo with its standard HeaterCore, a stock E3D V6 and the Bambu Lab hotend stop at 300 °C. The Phaetus Dragon and Dragonfly and the Slice Engineering Mosquito carry 500 °C ratings, but the heater and sensor you fit set the real limit. Slice sells the Mosquito Magnum+ with a 300 °C thermistor option, and the Dragonfly BMS ships with neither. For printing above 300 °C, the Voron hub covers hotends for engineering filaments.
Flow. Within one maker, the high-flow version is the larger step. E3D’s 0.4 mm High Flow nozzle moves 16 mm³/s of PLA against 13 for brass. Phaetus’s Dragon HF (high flow) reaches 31.5 mm³/s against 15 for the ST. Slice rates the Magnum+ at 90 against 35 for the Mosquito. The UHF (ultra-high-flow) and Magnum+ hotends are taller, so their printhead parts come from vendors or the community.
Nozzle system. A Revo nozzle is a nozzle and heat break in one unit, changed by hand while cold. E3D says Revo nozzles do not fit V6-style heater blocks. The Dragon, Dragonfly, Rapido 2, Chube Compact and V6 take V6 nozzles. The Mosquito family takes M6 × 1.0 nozzles with a 7 mm thread, and the Bambu Lab mods hold Bambu Lab’s own X1/P1 hotends.
What else changes. A hotend on Voron’s official list needs only new printed parts. The Mosquito route also swaps the Clockwork 2 for an LGX Lite, and the Dragon Burner replaces the whole toolhead.

E3D Revo on a Voron: Revo Voron, Revo Six or Revo Micro?

All three have official Stealthburner fronts and use the same Revo nozzles and HeaterCores, so E3D rates each at 300 °C and they share one set of flow figures. Only the mount differs:

Revo Voron. E3D developed this heatsink with the Voron team for the Stealthburner. It bolts on with four M3 screws (M3 × 8 in Voron’s list) and ships without a fan: the Stealthburner’s own hotend fan cools the heatsink. E3D sells it as the Revo Voron Coldside Kit and pairs it with a hotside pack carrying a 40 W or 60 W HeaterCore.
Revo Six. A drop-in replacement for the V6, held in the same E-V/R6 front.
Revo Micro. Screws into its front with an M12 × 1.5 plastic nut. Voron’s note: if the nut has a ridge, put it on top.

E3D gives the standard HeaterCore’s Klipper sensor as ATC Semitec 104NT-4-R025H42G, a built-in Klipper type, and supplies 1 m extension cables with Molex Micro-Fit 3.0 plugs.

Can you put a Bambu Lab hotend in a Stealthburner?

Yes, with community parts; Voron’s repository has no Bambu Lab printhead. Both Printables designs start from an adapter that Sam Schmidt shared in the Voron Facebook group to hold the Bambu Lab X1/X1C hotend “in a V6 like manner”. MrTeliP’s remix reshapes the adapter and the printhead front and rear around a hexagonal interface that prints without supports. Rincewind76’s version adds M3 heat-set inserts (5 mm diameter, 3.5 to 4 mm long) and M3 × 14 screws.

Bambu Lab rates this hotend only as part of its own printers: the X1 Carbon’s spec sheet gives a 300 °C maximum and 32 mm³/s in Bambu ABS at 280 °C. Bambu Lab publishes no thermistor model, and community configurations disagree on the curve. Check any sensor_type against a reference thermometer before printing, and keep max_temp at or below 300 °C.

What is the Dragon Burner Bambu hotend mount?

Dragon Burner is a community toolhead by chirpy2605, designed for the Voron 0.2. Version 8 lists the “Bambu Labs X1C” among its supported hotends. Its Bambu Lab hotend mounts come in versions for the Sherpa Mini, Sherpa Micro, Orbiter v1.5, Orbiter v2 and Double Folded Ascender extruders. On a Voron 2.4 it attaches through chirpy2605’s Trident and v2.4 parts, which replace the X carriage (MGN12H or MGN9H versions). An adapter plate for the stock Clockwork 2 carriage also exists, but chirpy2605 calls it “the least desired solution”: it has two mounting points and loses about 6 mm of Y travel.

The Dragon Burner takes the place of both the Stealthburner and the Clockwork 2. It carries twin 4010 blower fans, a 3010 hotend fan and an extruder of your choice, such as the Sherpa Mini or Orbiter v2.

What to check before swapping a Voron hotend

Print the right parts. Pick the front for your hotend and the rear for your extruder: files ending rear_cw1 are for the original Clockwork, rear_cw2 for the Clockwork 2. Only the Dragonfly BMO and the Rapido 2 have Clockwork 1 rears in Voron’s folders. A different hotend can also change the nozzle height, so set the Z offset again before the first print. Z offset at temperature shows the method.
Set the sensor type. Klipper’s sensor_type must name the sensor fitted: ATC Semitec 104NT-4-R025H42G for E3D’s 104NT, PT1000 for the Chube Compact and Rapido 2 Plus. For a directly read PT1000, Klipper assumes a 4,700 Ω pull-up resistor unless you set pullup_resistor, so check what your board fits.
Set max_temp. Klipper shuts the printer down when the reading goes above it. The reference Voron 2.4 config on Voron’s GitHub leaves sensor_type blank with max_temp: 270, and BIGTREETECH’s EBB SB2240/2209 sample config sets an EPCOS 100K sensor with max_temp: 250. Both are starting values, not your hotend’s rating. Keep max_temp within the lowest rating among the parts fitted: E3D rates its 104NT thermistor and Revo nozzles at 300 °C.
Keep thermal protection on. A wrong sensor type reads the wrong temperature, so the heater can overshoot without Klipper noticing. Keep verify_heater active (Klipper heater verification) and see firmware temperature limits before raising any limit. Running a hotend past its maker’s rating is at your own risk and can void its warranty (does upgrading void the warranty).
Run a new PID tune. Voron’s startup guide sets the part fans to 25% with M106 S64, then runs PID_CALIBRATE HEATER=extruder TARGET=245 and SAVE_CONFIG.
Check heater power against your board. Heater power runs from 30 W on the E3D V6 to 100 W maximum on the Mosquito Magnum+, with the Revo HeaterCore at 40 or 60 W and the Chube Compact at 80 W. Phaetus measured the Rapido 2’s ceramic heater at 92.9 W at 23 °C and 60.3 W at 300 °C. BIGTREETECH rates the EBB SB2240/2209 CAN toolboard’s hotend output at 5 A, which is 120 W at 24 V. That board reads one 100K NTC thermistor or PT1000 directly and a PT100 or PT1000 through its MAX31865 chip. Voron specifies 20 AWG wire for the hotend heater and says not to go thinner, for safety.
Plan the toolboard mount if the extruder changes. Bondtech’s LGX Lite parts for the Mosquito include EBB36 support, and chirpy2605 publishes separate PCB mounts for the Dragon Burner.
