Remove the four screws that shipped in the motor. Position the motor as shown and use M3x40 screws to attach the motor. Though no washers are shown in this photo, you should use washers when attaching the Z motor. The Z motor will not come apart when you remove the screws. The rubber gasket goes between the motor and the plywood.
If you can't get the rod to go all the way in, remove it and try going from the other direction. The laser cut holes can be tight.
The switch on the Z endstop should face the bottom of the printer. There is an adjustable white nylon screw that you'll use to position the build platform.
The collars prevent the smooth rods from moving when the Z platform moves.Push the collars so they are up against the frame on the top and bottom and tighten the collar set screws. Then tighten the set screw that connects the lead screw to the shaft coupler. The set screw that holds the shaft coupler to the motor is already tight.
You can attach the final frame piece but you may want to wait in case you need to make any adjustments.
