StealthChanger

Tool changing system for Vorons and other front mount printer motion systems.       Discord        GitHub Sponsors

Overview

StealthChanger converts a Voron 2.4 (and other front-mount motion systems) into a multi-tool printer. The shuttle exchanges toolheads that are mounted on backplates and docks at the front of the machine. Bushings, pins, and magnets create a rigid connection, while OctoTap sensing provides TAP-style Z probing.

StealthChanger builds on projects such as tapchanger and the work of many community contributors. Join the community on Discord to see what is new and share your build.

This is a challenging conversion, even for experienced Voron builders. Expect reprints, tuning, and iteration. Start with these resources:

Hardware

Shuttle & Toolheads

The shuttle replaces the stock Voron carriage with a bushing-and-pin interface that mates to each toolhead backplate. Backplates and docks exist for many toolheads (Anthead, Stealthburner, Dragonburner/Rapidburner, A4T, SV08, Yavoth, XOL, Mini Stealthburner, Blackbird, and more). See the Toolheads overview for comparisons and BOMs.

Docks & Mounting Hardware

The modular dock holds tools when they are not in use. It can mount to a front crossbar, door buffer, or top frame. Learn about Docks, crossbar, and door buffer strategies on the Docks page.

Electronics & Cable Management

Multiple toolheads mean more wiring, CAN/USB connections, and filament paths. Key resources:

Enclosure / Top Hat

With docks mounted high and umbilicals arcing upward, most enclosed printers need a taller top enclosure. Options include printable top hats and 2020 extrusion frames. See Top Hat.

Probes & Endstops

Physical probes (Sexball, Nudge, Axiscope, etc.) and relocated endstops simplify tool alignment and gantry homing. Hardware details are covered in Probes and Endstops.

Building

  1. Plan the build – Checklist and Bill of Materials
  2. Order parts – Vendors and Kits
  3. Print components – Printing guide
  4. Estimate cost – Approximate cost calculator
  5. Visualize the assembly – Reference CAD (.step) by N3MI

Software & Configuration

Klipper must be toolchanger-aware for StealthChanger. The typical flow looks like this:

  1. Installation – install klipper-toolchanger-easy to add StealthChanger macros and configs
  2. Configuration – set up tool files and toolchanger settings for your hardware
  3. Toolhead Calibration – set probe offsets and tool alignment
  4. Dock Calibration – set dock positions for reliable tool changes
  5. Slicers & Macros – configure slicer and macros for multi-tool printing
  6. LEDs – optional post-install lighting effects and status indicators
