Description
Please note: For the current Mk3 installation, do not follow this guide… use our Basic Installation Instructions instead that uses the 3DChameleon to feed the stock extruder as it is.
These are mounts for the new 3D Chameleon Mk2 to replace the stock extruder with the 4 color 3D Chameleon Mk2. It includes the base plate, mount plate and endstop mount plate.
Quick Steps to Install:
Step 1: Swap the PTFE tubes to the other side of the 3D Chameleon. The 3D Chameleon, by default, has the output PTFE tubes on the top right side… but for this installation, you need to carefully remove the top of each layer and move the PTFE tubes to the top left side. Once that is done, you can reassemble it. Again, be very careful separating the layers… do not force them apart, but use a small flat blade to evenly separate each layer all the way around. I've included a picture of how the layers go back together incase it falls apart. (There are springs inside it and their placement is critical.)
Remove the stock extruder... disassemble it and remove the stock motor. (Leave it connected to the printer wiring.)
Add the Mk8 Drive Gears to the Stock Motor (Removing the stock drive gear) and mount the motor the the 3D Chameleon using the four 30mm (black) M3 screws.
Mount the 3D Chameleon to mount "B" using four 35mm M3 (silver) screws.
Mount part "A" to the stock extruder location using two of the factory 12mm M3 screws previously removed from the stock extruder.
Use four small zip ties to mount the 3D Chameleon (attached to Block B) to the frame (Block A) by passing the small zip tie through the two holes in the top of each block as well as the two bottom holes... pull zip ties tight and trim off excess.
Attach the 3D Chameleon limit switch to the front right frame rail under the right side smooth rod using the T4 4040 T-Nut.
Connect the wiring as per the 3D Chameleon instructions.

Replace the 8 tension tuning sliders with the supplied (Center x 4) and (Outside x 4) inside the 3DChameleon sliders (that hold the bearings). Make sure you evenly separate the parts so that the pins don't break. (If they do, don't worry, you can print new ones from here: https://www.printables.com/model/354998-3dchameleon-bc-replacement-parts-with-ptfe-grip)
Reassembe the 3DChameleon and attach the “Mount B” to the 3D Chameleon using four 35mm M3 (silver) screws.
Mount part "A" to the stock extruder location using two of the factory 12mm M3 screws previously removed from the stock extruder.
