I ordered my kit Nov 4th 2021 "3DChameleon 4 Color MK2 Add-On Kit INTERNATIONAL SHIPPING" I struggled to get it working, then got really busy and never got back to it until now. It sounds like there's an MK3 version now. It looks simplified compared to the MK2, so I'd like to upgrade. I see that there's an MK2-MK3 upgrade kit, but if I have the "MK2.5" then it's not necessary as the hardware is the same? What's the best way for me to tell which version I have? Perhaps just the date/order above is enough information? Hopefully I have the 2.5, and can simply flash the firmware following this post: https://www.3dchameleon.com/forum/getting-started/mk3-firmware-upgrade-instructions

I was having a heck of a time trying to do my 4-color 3dchameleon install on my Ender3 V2 using the "classic" method, where the chameleon extruder simply loads the filament into the primary ender3 extruder, but the primary extruder is what is used during printing. I decided that eliminating the primary extruder and using the 3dchameleon as loader/unloader AND extruder was just going to simplify everything from the gcode to having one less step to go wrong. I followed this video (linked from the FAQ): I think I've finally got my gcode figured out, and I'm able to successfully load and unload a single color (lets say extruder 2). Unfortunately, I noticed that when I use the same gcode on extruder 1, the extruder is moving in reverse.. which probably makes sense since one of the gears is on the opposite side. I realize I could just swap the extruder instructions in my load/unload by swapping positives and negatives, but that won't help during the actual printing where I might be switching between colors during print. How would I be able to have the extruder direction "inversed" for 2 of the 4 gears, using the above configuration?

I just received the 3d Chameleon MK2 4 Color kit I ordered, and before installing it I started pulling up videos on the installation process for my Ender 3 Pro. A lot of the videos seemed to be for the MK1, so I went back to https://www.3dchameleon.com/ to get a better understanding of the differences between the MK1 and the MK2 (the one I ordered) and how it might affect the installation. It was at this point I notice a slight change in wording near the "add to cart" buttons. There is a "Starter Kit" and an "Add-On Upgrade Kit". I had not noticed this before, and likely clicked on the "Add-On" kit thinking it was an "add-on" to my existing printer, and now I'm worried I have an "Add-On" kit that I won't be able to use. What is the difference between the "Add-On" and "Starter Kits", specifically in terms of the contents that are shipped in the box? What's the easy way to tell which one I currently have and if I do have the "Upgrade Kit", is there any workaround to still use the "Add-On" kit without having the "Starter Kit"? Perhaps something I can just print?
