Place one Z linear rail assembly on the designated T-slot.
-
Insert the two align_40120_mgn15 printed jigs in the T-Slot and rail.
-
Make sure the align_40120_mgn15 printed jigs are correctly placed and centering the rail on the T-slot
-
Tighten the linear rails screws one at a time starting from the front and making your way towards the back, one by one.
-
MGN15 Rails should be tightened to 98 N-cm of torque, overtightening the screws will result in rail binding.
-

-
Place the second Z linear rail assembly on the T-slot but DO NOT tighten the screws.
-
Install the Z Joiner assembly on the linear rails.
-
Using the 16x M3x6 Cap Head screws, fasten the XY joiner plate assembly to the mgn15 carriages.
-
MGN15 Rails should be tightened to 98 N-cm of torque, overtightening the screws will result in rail binding.
-
Tip: Blue thread lock can be added to the thread of the M3x6 Cap Head screws.

-
While the second linear rail remains loose, the Z plate should move smoothly without resistance. If you experience any binding or drag, slightly loosen the carriage screws, as they may be overtightened.
-
Be careful to ensure that the Z joiner plate carriages do not detach from the linear rail during the process.
-
Move the Z joiner fully to the front as demonstrated. Then, gradually move it toward the back, exposing one linear rail screw at a time, and tighten each screw as you progress.
-
Ensure that all linear rail screws are tightened from front to back. Avoid overtightening, as this may cause binding and restrict movement.
-
MGN15 Rails should be tightened to 98 N-cm of torque, overtightening the screws will result in rail binding.

-
Install the Thrust Bearing on to the exposed end of the Lead Screw as shown
-
Lock Collar
-
The Precision Shim 12x8x1mm should be in between the 688ZZ Ball bearing and the Lock Collar
-
