INSTALL X CARRIAGE AND GUIDING RODS (continued)

Using 4 M3 x 12 SHCS, lock the rods in place at the X ends.

Tighten the bolts holding the bearing holders on the X carriage making sure it still slides freely back and forth.

Tighten the bolts holding the double bearing holders on the X ends at this point as well.

Does the x carriage slide smoothly back and fourth?

Did you tighten all the bearing holder bolts?
