Tighten everything down by pushing the lead screw all the way towards the motor shaft while pushing the coupler
all the way towards the bearing, then tightening down the two set screws on the coupler to clamp down onto both
sides. Ensuring that the face of the coupler/washer is flush against the bearing is important to prevent any play in
the lead screw. Do this on both sides.
Back at the front of the machine, the last two of the ACME locking nut assemblies are going to be used to
constrain the lead screws on the Y-axis. These share the same purpose with the locking nuts on the X and Z-axes,
where the combination of the nut on one side and the coupler on the other side keeps the lead screws from
moving side-to-side; so it’s a good idea to check that everything is secure by gently pushing and pulling on the lead
screw to check for any looseness. Do this on both sides. Adjust the couplers and tighten the ACME lock nut more
if you feel any play, since you should be able to rotate the lead screw freely but not feel any side-to-side looseness.
Everything tightened down
Thread on the ACME lock nut, making sure it’s tight against the bearing before tightening the screw to secure
