"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
