ABL and accuracy, which probe to choose?

That sounds quite good - seems that I’ve ordered mine too early.

that applies to this inductive probe also, leaving me with not enough headroom again. I have tested the GX-F12A and put it on a peeled off ‘first-layer (0.2 mm)’ and had to press it down to get it triggered. That is way to tight.

So I count on the 4mm sensing range of the BDsensor which might reduce to 2 mm leaving me with a headromm of at least 1.5 mm, which I might can handle with my mechanics.

My print head is completely homebrewn and by far not as sophisticated as yours. But the CR-Touch has an X offset only (30mm) and shares the same Y axis.
