Hi Flonko,

I'm new to Prusa/3D printing as well and had a similar problem with my nozzle starting out slightly higher than I had positioned it with the homing sequence. My solution so far has been to input a "Z offset" amount of -0.2 mm in my Slic3r software. That fixed it. Yours would require a lot more height adjustment than that (not sure if Slic3r would support -10 mm). I am curious if you have solved the problem differently by now.

I'm currently using version 0.9.9 of Slic3r (as recommended by MakerFarm), but I'm building the courage now to upgrade to the latest 1.2.9 version.

Chachin..
