Prusa i3 – Build Manual
Next screw the two M5 threaded rods through the M5 cage nuts .. they should thread through very smoothly, if
not don't force it , check the alignment, clean and oil the threaded rod and try again. Also you can try screwing
in the other end of the rod which may have a better start to the thread. Screw the threaded rods all the way
down into the top M5 openings of the flexible CNC connectors to a depth of approx 8 mm, then tighten the
grub screws gradually alternating between the two grub screws so as to keep the rod centred. Twist the
connector and note the play at the top of M5 rod, it's ok if it has 'some' visible play on rotation.
