STEP 42 Assembling the Z-axis
There is a screw head on the underside of the Z plate bottom which must be
properly seated in the round groove in the MINI-Z-bottom. Follow these instructions
for the correct installation:
Place the extrusion assembly on the MINI-Z-bottom like in the picture and
slightly tilt the extrusion. Move the inclined extrusion to the edge of the plastic
part (see the yellow circle).
Straighten the extrusion to 90 °.
STEP 43 Assembling the Z-axis
Make sure there is no large gap between the Z plate bottom and the plastic part.
Secure the Z plate bottom with two M3x20 screws.
Insert one M3x12 screw in the Z plate and tighten it.
Insert the M3x40 screw into the hole in the MINI-Z-bottom.
Using the 2.5mm Allen key insert the screw through the entire part so that a tip of
the screw is visible on the other side.
