Hello friends, does anybody know a 3d printer guru in Berlin, Germany that can I can hire to my house and calibrate my printer? Got the sensor working and it auto calibrates it but it still won’t be at the proper paper thin level, everything else seems to work properly. Its a Sunhokey Prusa i3, mks gen-2z v1.2 and I wired directly to the zendstop a LJ18A3-8-Z/BX. All I managed to print is a 1cm cube but I struggled to do this.
I am at the end of my ropes, I am very close to giving up and selling it :< I live in Mitte next to U6 Schwartkophstr. station.

Dude, you are in Berlin… There’s even 3d printing service shops…
