But how does this work in practice as the microswitch has to be lower than the nozzle or can you flip your nozzle or something like this? If I understood you correctly you can even use the auto bed levelling so what is the trick?

That looks very interesting and I had no idea that the firmware supports negative values for the z-homing-value. It is probably more ccurate than the proximity sensor but I am wondering how precise such a microswitch is according to the repeatability especially if you use such kind of lever as we ware taking about accuracies of 0.1mm. What I really like is that you can use different build surfaces without changing any settings. I think that I will add this feature in some weeks. But what about BuildTak? In the instruction manual they are warning to get the hot nozzle in touch with the surface but probably it is the meovement that reduces the life of it.

I often have a wrong high when starting a print job so I have to redefine the z-value while the nozzle is hot.

... Besides the proximity sensor may affected by infrared light caused by heat so I will get more accurate readings with the same temperature...

I always home Z (at the centre of the bed, using my sensor) just before printing, when the nozzle and bed are close to printing temperature, so that the Z=0 setting allows for thermal expansion of the nozzle and the bed.

Especially using BuildTak means that you may have to re-adjust the z-height ten or even twenty times if you are afraid like me.

The BuildTak is very sensitive of a too low nozzle height. As it is much more expensive than Kapton tape I am very careful using it. Secondly it is another philosophy. As in normal circumstances you squeeze the first layer a little bit you have to keep the nozzle a little bit higher. If you squeeze the first layer you already my have damaged the BuildTak already in a way that it is not usable anymore (at some areas)..
