Consult our linear rail guide to prepare you rails
-
The kit comes with different length MGN12 rails with one MGN12C carriage on each rail for:
-
X - 1x 400mm for the 2020 extrusion
-
Y - 2x 350mm for 3030 extrusions
-
Z - 3x 400mm for 3030 extrusions
-
-
-
Insert all M3 screws and T-nuts into the rails:
-
For the 3x Z 400mm rails use 3030 T-nuts and DIN912 M3x12mm screws
-
For the 2x Y 350mm rails use 3030 T-nuts and DIN912 M3x12mm screws
-
For the X 400mm rail use 2020 T-nuts and DIN912 M3x10mm screws
-
The ends of the rails are secured with bumpers that prevent the carriage from sliding of the rail - those need to be removed for the final assembly. Once you need to remove those be careful not to drop the carriage as it will most likely loose all it's bearing balls!

-
Do not bolt down all of the screws yet, just secure the rail by the two screws on the ends - later adjustment maybe required
-
Attach the 3x 400mm Z rails into the frame
-
Measure the space between the side of the rail and the side of the extrusion - for 3030 it should be 9.00mm on each side - measure each rail in 4 points

-
Attach the Y MGN 12 rails on both sides of the printer
-
Use the 3030 corner bracket in the back as reference - the rail should touch the bracket
-
Measure the space between the side of the rail and the side of the extrusion - for 3030 it should be 9.00mm on each side - measure each rail in 4 points

The X rail - the one that will end up on the 2020 extrusion will be assembled later. The final fastening of the rails will happen further in the assembly.
