The Mk4 comes in two versions... the Mk4 and the Mk4 Pro. The 3DChameleon Mk4 or Pro are not actually products we sell, but a 4 color system and associated ecosystem of add-ons that are freely available open source designs that extend the functionality of the Mk4. In addition to some cool new features (like "Select Random Filament" and "High Speed Mode"), the Mk4 firmware brings with it new capabilities to extend the capability of the base system. For example, our initial add-on designs include an OLED display, 3DClippy Automatic Filament Cutter, 4 Filament Runout Failover Sensors, Extruder Motor Position Sensor to enable Automatic Calibration, and a Filament Dry Box with built in Filament Buffer. The Mk4 firmware is open and extensible with future upgrades as well. See our "Getting Started" forum for more information. None of these add-on devices will be sold by us, but instead will be provided as a bill of materials, detailed assembly instructions, printable STL files as well as details videos describing their operation and function. We will also include links to where the parts can be easily obtained. These features will be released over the next few months.

Yes. It's designed to be universal (and work with any printer that can handle 1.75 filament), so if your printer is stock and has the ability to use custom tool change gcode, then it should work without issue. Some custom configurations will need slight alterations for the switch or extruder mounting location.

3DClippy is an open source filament cutter to allow users to avoid the hassle of tip shaping of the filament so that it can be reinserted correctly. The 3DClippy is a guillotine that simply cuts off the tip and leaves it inside the hot end to be purged on the next filament load. It is recommended that you implement the 3DClippy if you want to avoid the difficulties of tip shaping of every filament. We do not offer technical support, nor do we sell, the 3DClippy.

The 3D Chameleon is universal and works with any printer. No firmware or electrical modifications are necessary. ​

The 3DChameleon uses a standard 12v 1amp wall wart power supply with a 2.1mm plug. The specified power supply will work with 100-240 volts @ 50 or 60hz when plugged into the appropriate adapter.

Yes, the 3D Chameleon can be combined together to allow up to 32 colors. (Note: this is limited by the current slicers at this time, not a physical limitation of the 3D Chameleon.)

Yes, you can use the 3D Chameleon to load and unload your existing extruder without issue.

Yes, you can mount the switch at the top or side of any column or you can optionally use a GPIO pin to communicate with the 3DChameleon's electronics.

Currently, we have sample code for PrusaSlicer, Cura, Simplify3D and Grid Space's Kiri:moto for the Mk2 and PrusaSlicer, OrcaSlicer and BambuStudio for the Mk3. You can use our GCode Generator tool (linked above) to generate code for each one and paste it into your working profile. (Kiri:Moto uses the same code as Cura.) We highly recommend PrusaSlicer or Kiri:Moto as they support the most modern multimaterial concepts. (Note: Cura only works well with 2 colors... more than two cause issues with their purge tower strategy, and is not supported at all with the 3D Chameleon Mk3.)
