Hi,
yesterday I finished my Prusa I3. Everything seems to work pretty well. The heating elements are heating up, i flashed the firmware and adjusted the steppings. All motors move in the right direction with the right distance. But when it comes to printing, i get a problem which i cant solve. After the homing of the axis, when the extruder and the bed are heated up, my z axis moves up 50mm and the printer starts printing in the air. But when i move the z axis manually for 10mm, the axis moves for 10mm... so it seems to be configured right. I can't find the Solution :-( can anyone help?
