Five toolchanger projects fit Voron printers, and each one is built around a particular frame. This page lists which Voron each fits, how its tools couple, how many tools fit and what a kit costs, all taken from the project docs and vendor listings.
A Voron 2.4 has the most options: StealthChanger, TapChanger and MissChanger v1 all target it. A Trident takes MissChanger v2, MadMax or TapChanger with its motorized Liftbar dock, and Bondtech’s INDX toolhead fits either frame with its own X carriage. A V0 has one documented route, MadMax, so far only with two heads.
Five projects fit Voron printers. StealthChanger, TapChanger and MissChanger v1 convert a Voron 2.4, and TapChanger’s Liftbar dock also fits a Trident. MissChanger v2 is built for the Trident. MadMax converts static-gantry printers such as the Trident and V0. Bondtech’s INDX toolhead mounts on a Trident or 2.4 with an MGN12H carriage.

What decides the fit for each frame:
- Voron 2.4. The gantry moves in Z, so StealthChanger and TapChanger use that motion to pick tools from docks fixed to the frame. StealthChanger’s toolhead table allows 4, 5 and 6 narrow tools (Dragon Burner, Mini Stealthburner, Rapid Burner, Yavoth, AntHead) on 250, 300 and 350 mm frames, and 3, 4 and 5 wide ones (Stealthburner, XOL, A4T). LDO’s kit lists 5 tools for a 300 and 6 for a 350.
- Voron Trident. The gantry is fixed and the bed moves, so frame docks need another way to make the vertical pickup motion. TapChanger adds a motorized crossbar, the Liftbar: one motor for up to 3 toolheads, two motors for more. MadMax avoids Z motion entirely: its tools hook onto docks with XY moves only. MissChanger v2 is designed for the Trident. The StealthChanger docs describe it as converting “any flying gantry printer” and list no Trident setup.
- Voron V0. MadMax is the only documented route; details in the next section.
More detail: StealthChanger, how to build a StealthChanger and Bondtech INDX.
Yes, through MadMax. This beta conversion lists two Voron V0 builds, each printing with two toolheads, and no MadMax build has run more than two heads yet. StealthChanger publishes tool counts only for 250 to 350 mm Vorons and the Micron 180. TapChanger describes itself as a toolchanger “for Voron 2.”
What the two V0 builds in MadMax’s list used:
- MM.001, a V0 120. Vampire Bat gantry parts, DragonBrick toolheads, V0 docks and custom K1 extruders.
- MM.009, a V0.2 120 widened 30 mm in X. Docks and DragonBrick heads by the MM.001 builder, LGX Lite extruders and a customized extra-wide Vampire Bat gantry.
What to plan for on a V0:
- Toolhead width. The MadMax FAQ says two Mini Stealthburners (57 mm wide) do not fit in a normal V0 with room for a front Nudge probe for automatic alignment. It points to OmniBrick, DragonBurner or DragonBrick instead.
- Print area with both heads. On a two-head print you lose the two front corners, and on a narrow printer like a V0 that front strip is “usable only for prime lines.” For single-head prints, detach the second head to get back nearly the full volume.
- Coupling. The tool is held on by magnets with no mechanical lock. The README says if a head detaches, the firmware immediately puts the printer into a safe state.
- Skill level. The README calls it “an advanced mod”: expect to edit Klipper configs and possibly make small CAD changes for your printer.
What is the difference between StealthChanger and TapChanger?
The difference is the coupling. TapChanger’s shuttle rides bearings on rods in a self-aligning kinematic mount. StealthChanger, derived from TapChanger, uses bushings and pins held by magnets. In both, each tool’s backplate attaches to a shuttle on the X carriage. An OptoTap sensor reads the shuttle’s movement as the nozzle probe in place of the stock Voron Tap.

TapChanger |
StealthChanger |
| Origin |
viesturz |
DraftShift Design; README says “Originally based on Viesturz’s Tapchanger” |
| How the tool couples |
An “oversized linear rail” with about 4 mm of travel: bearings riding on rods (plate and square-rod versions exist), a kinematic mount that is “self aligning” |
Bushings and pins, held by magnets, letting the backplate “kinematically attach to the gantry” |
| Z probing |
The shuttle’s travel is the probe, read by an OptoTap sensor; the README claims the “same rigidity and probe accuracy as Tap” |
The constrained motion “serves as a TAP probe”; it replaces the Voron Tap hardware and reuses only the OptoTap sensor, one per tool. The docs also cover eddy-current probes |
| Wiring on the shuttle |
None (“no wires on the shuttle”) |
Each tool carries its own heater, fans, extruder and OptoTap wiring; the docs recommend a toolhead board on every tool |
| Toolheads |
Dragon Burner by default; Stealthburner and Mini Stealthburner with limited support; Rapid Burner and XOL versions experimental |
Stealthburner, Dragon Burner, Rapid Burner, Yavoth, AntHead, A4T, XOL, Jabberwocky, Archetype BlackBird; Mini Stealthburner as a user mod |
| Docks |
Hook-on, top-mounted, and the motorized Liftbar for Trident or 2.4 |
Modular Dock, on a crossbar (recommended), tied to the frame, or hung from the top |
| Current version |
V4.3 |
V1.1, not compatible with earlier shuttles and backplates |
| Firmware |
Klipper with klipper-toolchanger |
Klipper with klipper-toolchanger; the docs say Kalico “does not work for TAP based probing” |
| Kits |
None listed |
LDO kits, Fysetc CNC shuttle and other parts through listed vendors |
On rigidity, DraftShift says its design needs fewer parts and that “input shaper tests have shown it to be as rigid if not more than current Tapchanger.” Team FDM’s August 2026 roundup credits TapChanger with fitting “up to six tools across a 350mm Voron 2 frame” and notes that on a Trident, docks bolted to the frame “sit in exactly the same place forever.”
In practice, going by the table: StealthChanger is the one you can buy as a kit, and TapChanger is the one with a documented Trident dock.
Expect $100 to $200 per tool for a DIY build of an open design (Team FDM estimate), or $246.70 to $549.20 for an LDO StealthChanger kit for the 2.4, before hotends and extruders.

The LDO kit also leaves out the power supply, and West3D tells buyers to size it to the number of tools. Software setup for the open projects runs through Klipper, and the INDX development kit runs Kalico, Klipper or RepRapFirmware; see configuring klipper-toolchanger and calibrating tool offsets.
