Did you ever resolve this issue? Here is what I have found and will choose a solution for my newly purchased 3D Chameleon.

The left side of the x-axis and the back of the y-axis switch already has a Creality switch, assuming this will interfere with homing.

The right side of the x-axis has the optional Creality g-sensor. The 3D printed mount for this g-sensor already collides with the mount for the camera. A mount can be added on this side but might be best to re-design the g-sensor to extend a bit forward. Also need to find a way to securely mount the 3DC switch.

The front of the y-axis extends far beyond the base and nothing to attach to the base to trigger at the end. The right side of the bed has a pair of screw holes where the g-sensor for the bed reading. If I mount the g-sensor on the actual bed with double-sided tape while taking a reading then I can redesign and reuse this mount point to trigger the 3DC switch from underneath the bed.

Chris also has a great cheat sheet of instructions you'll find from his videos, but here is the link to get you to it quickly w/out hunting for it.

It might help to post a close up picture or two of your X/Y Axis on your Ender 3 v3 KE. It is a different beast from many of the Creality printers I'm familiar with.

There are a variety of mounting options that can be found here. https://www.thingiverse.com/thing:4663605

Note that you don't necessarily have to mount it with a screw, etc., you could use 3M mounting tape or something suitable. So long as it is mounted in a way that the bed moves towards the switch, it can hit it and trigger the 3D Chameleon at the extent of any of the axis.

Bill's setup in a video posted recently on YouTube shows it mounted on the X axis, with what looks like 3M mounting tape.

Also check out Chris Riley's series of videos on the setup. He walks through it pretty thoroughly for setting up. This is Part 2: https://youtu.be/sq4maecRiSM?si=ZBSS7fVb-KGZ51GW

Hi Bill,

I did and it really didn't help me out much. I'm lost as to where to place the switch on ender 3 v3 KE and how it will work with a direct drive.

I can't really answer your switch question, but I can answer about direct drive. The Chameleon simply switches out the filaments that are fed to your printer's extruder. Example toolchange (maybe this will help):

Printer extruder unloads until it is no longer gripping the filament
3DChameleon receives the limit switch signals and starts to pull out the filament to the Y Splitter
3DChameleon receives more limit switch signals and starts to push in the next filament to the printer's extruder
Your printer's extruder grabs the filament and prints normally
When not toolchanging, the Chameleon moves into a neutral state so that it is no longer gripping the filament.

At the front of the Y axis??? Typically, that's where Ender style printers use it. There are many styles of mounts available on Printables/Tinkercad.

As for Direct Drive, it's literally no different than a Bowden System. The 3DChameleon has no knowledge of the extruder or it's placement... it's only function is to load and unload the extruder. The only difference between the two from our perspective is the distance between the drive gears and the nozzle, which you enter into the gcode generator. That way the printer can unload the filament the required distance during the change.
