MissChanger v1

Change Log:

250906 - Better perform & easier to build

• Replaces threaded inserts with M3 nuts → Ease of assembly and increase heat resistant.
• Add the option to print the T&C TH-side in one piece → Ease of assembly.
• Increase clamp gap in Bar Ends → for better clamping force.

250717 - Initial release

• The legend begins :)

Description

MissChanger aims to be a tool-changing upgrade that is compatible with both Voron Trident and Voron 2.4 (Trident compatibility is pending). While also retaining the accuracy and reliability of the MGN9H tapping system of Voron-Tap.

Creator Note: This project is released to Printable as a paid model. It is the result of nearly 2 years of work, and I hope that the quality of justify the asking price. Nevertheless, for those who cannot afford it, all files and instruction are available for free on Github.

Other features of MissChanger includes:

• The ability to quickly and toollessly convert between tool changer mode and single nozzle mode (for when you need the full print volume of the stock printer).
• Nozzle brush dock. For cleaning the ooze and build-up after tool-change.

Compatibility

Printers:

• Voron 2.4 350 (up to 5 SBs)
• Voron 2.4 300 (up to 4 SBs)

For those who want to adapt MissChanger to you own system. The Bar-Ends are 28mm each, and each dock is 80mm in width. All will be riding in the grove of the 2020 aluminium extrusion frame.

Toolhead:

• Stealth Burner

Hotend:

Any hot-ends that does not require a custom/extended main-body for the Stealth Burner should works just fine. Nevertheless, the follows are those that has been tested on the reference machine:

• Revo-Voron - Recommended.
  • It is officially supported for the Stealth Burner.
  • It has the the right amount of thermal mass to keep the nozzle temperature stable, while still havHotend:Hotend:e decent heat-up and cool-down time.
• Phaetus Dragon - Not recommended.
  • The heater block causing slow heat-up and cool-down. This is not ideal, since it is beneficial to lower the tool temperature when it is docked for a long period of time.
  • The cold side of the hot-end is inadequate to cool PLA in a 30°C+ chamber, eventually causing heat creep if the heater is constantly on.
  • Close proximity between the heater block to the plastic causing deformation. This does not resulted in critical failures, but the affected parts will not work on any other assembly.

Extruder:

All extruder that is compatible with the Stealth Burner should works just fine. Nevertheless, any added dimensions on top of the Clockwork 2 might resulted in less print area or space for other tool-heads.

ClockWork 2 (CW2) - Default

• All quoted clearance dimensions are in reference to this extruder.

Galileo 2 Extruder (G2E)

• The thumbscrew stick out ~8mm to the left. Thus, taking up more docking space than default.

Assembly and Software

• BOM, STLs, and instructions are in the STL_&_Assembly folder (for the latest and relevant versions), or MissChanger Archive (for past versions).
• For the latest Alpha / Beta / Release version. Set-up instructions are available here: Klipper_Config.
