Introduction
It's assumed that you're building a kit from Filastruder, and you've completed all previous sections. At the end of this section you should have a complete frame assembled for your RailCore.
-
-
Using (16) M3x10 socket head screws and (16) M3 washers, attach the bottom to the frame.
-
Loosen your corner cubes when attaching the bottom or sides to the frame. The acrylic pieces will attempt to pull the frame into square.
-
Be sure the bottom panel is in the right orientation. The side with (5) large holes should be on the right side of the printer. For reference, the bottom right extrusion should have (10) M3 nuts in it's top channel.
-
-
-
Each Z tower consists of the following printed parts: (1) printed Z yoke and (2) printed Z rod holders.
-
For each printed part insert (2) M3 nuts and (2) M3 x 20 socket head screws. You should do this for all 9 of the printed parts.
-
-
-
The top of the Z towers will fasten to horizontal extrusions on the left and right sides of the frame.
-
Attach corner cubes to opposing ends of the extrusion with (1) M3 nuts inside the extrusion channel and (1) M3 x 10 socket head screw for each corner cube.
-
A small hole should face up and towards the outside of the extrusion. Use the image as a reference.
-
-
-
Set aside 3 printed Z rod holders. Using (3) M3 nuts and (3) M3 x 10 socket head screws, prepare each rod holder to slide into the extrusions.
-
Mount (2) Z rod holders to the right extrusion by sliding the M3 nuts into the top channel. Place (2) M3 nuts into the channel between the (2) rod holders. Tighten the Z rod holders to the extrusion just enough to keep them from moving freely.
-
Mount (1) Z rod holders to the right extrusion by sliding the M3 nuts into the top channel. Tighten the Z rod holder to the extrusion just enough to keep them from moving freely.
-
Note the proper orientation of the Z rod holders and corner cubes using the provided images.
-
-
-
On the right side of the frame, attach (2) Z rod holders to the bottom right extrusion using (6) M3 x 10 socket head screws.
-
On the left side of the frame, attach (1) Z rod holder to the bottom right extrusion using (3) M3 x 10 socket head screws.
-
-
-
Attach both the left and right Z rod holder extrusions to the frame using the corner cubes and existing M3 nuts in the inside channels.
-
Using M3 x 10 socket head screws for each corner cube, attach each to the frame. Do not tighten the corner cubes to the frame at this point.
-
Use calipers to measure the distance between the bottom of the top extrusion, and the top of the Z rod holder extrusion. Tighten the corner cubes to the frame leaving a gap of 50mm as shown in the image.
-
This step is easier with the frame on it's side.
-
-
-
In each printed Z yoke, insert (2) bushings.
-
Center the bushings as shown before tightening the (2) M3 x 20 socket head screws you installed earlier.
-
Be careful not to overtighten. they do not need to be tightened to the point of the printed faces of the clamp touching.
-
-
-
Loosen the M3 x 10 socket head screws holding the Z rod holders to the frame.
-
Slide the (6) smooth rods through the top Z rod holder and through the Z yokes. Each Z yoke should be facing flat side up.
