Interchangeable head about 3dplacer HOT 1 CLOSED

Hi,
Thanks, I am looking for an easy way to switch, currently it can interchange between 3D printing and pnp with 2 screws, and require to adapt 2 fan wires, to go for full interchangeable, existing printer need to adapt also the hot end cable and temperature sensor and Bowden tube, I plan to first remove the need for 2 screws, then later full switch, but keep both options available.
For the placement, I got around 0.1mm accuracy without modifications on firmware of 3d printer, for me the 0201 could deviate a bit, but got pull back to pad during reflow, then I change the minimal step in Marlin fw(most of 3D printer combine several step to 1), then I got around 0.02 to 0.04mm) which is much better, so yes, fw itself also has room for adaptation regarding pnp functionality, I will make a video to show also about this topic.
