i try to assemble my new Prusa i3 Pro C Dual Head.
When I mount the pre-assembled extruder on the extruder support
the hot-end touches the screws of the extruder holder as seen in picture 1
so i cant fixing the extruder screw in the first hole
Picture 1 I'I think the problem is, that the extruder has been changed and is now no longer high enough
Picture 2 Picture 3 Or have I done something wrong..?
Excuse my bad English
