Great work!
Just for interest (and as I plan to do something similar on my UMO) - where have you changed the docking position - in Cura or Marlin?
Currently I have also issues to understand, how the z-switch/hight modification is done, but I guess thats another story...
Any hints appreciated... 🙂
The Mark2 Firmware handles all of that. I adjusted the docking position from the Ultimaker OLED display, that menu allows you to set the X & Y position to move to. It turns out that the same motion to dock and un-dock the magnetic 2nd head also works great for flipping the lever on the head to lower or raise the 2nd CORE

I got the nozzle switching happening smooth now using Mark2 Firmware. I just had to edit the nozzle offset to 18mm and set the docking position to X=225.8 Y=180.4 nice and smooth now.
next step is editing the Mark2 files / profiles to work in Cura 4
UM3 conversion :-)

Looks great - any plans to sell upgrade kits? 🙂
"setting_version" for the variants is now 7
I think, that's all - "cura.log" gives you more hints, if it doesn't work.

Thanks Tinker ! no plans to sell any kits, it's not very practical I guess.
The only thing I needed was 2 sets of the 2+ extruders which I had from doing the originall Mark2 conversion. and 1 UM3 head with the cores.
I just printed the 3D model from the Git hub for the Nozzle shift lever bracket. used the location from the UM3 cad model to drill my UM2 side wall for the bracket.
I totally gutted the UM3 head lol. I removed all of the IC's and the resistors, then I manually jumper wires form the core contacts up to the main cable header.
and of course the Z- sensor is non operational. ( super easy to level the plate anyway)
At the end of the day what I ended up with is a :
UM2+ Mark2 with quick change CORES 🙂
