Check that you have all of the following:
-
3D Printed Parts (x4)
-
Rails (x4)
-
Fastener pack
-
5x8 Coupling
-
M4 Threaded Inserts (x11)
-
You will also need (not included):
-
Allen keys, Drill with metal bits (2mm/3mm), Pliers, Soldering Iron (for threaded inserts)
-

-
Begin by disassembling the platform from the base.
-
Do this by first untying the belt from the platform.
-
Then remove the heated bed and place it to one side, you don't need to disconnect its wiring.
-
If you have the Pi Camera installed, unmount it also, again you don't need to disconnect it from the pi board.
-
Finally, remove the old HDPE linear guides holding the platform in place.
-
The platform should now be free for the next step of drilling the holes for the linear rails.
-
-
-
Next, remove the tool carriage and Y-belt from the gantry. Do not cut the belt, it will be re-used.
-
Free the y-endstop from the gantry.
-
Disconnect the y-motor from its cable.
-
Use side cutters to break the cable ties holding the cables to the gantry.
-
Free the lead screw coupling from the z-motor shaft.
-
Finally remove the HDPE linear guides from the gantry and the entire gantry part should now be free.
-

-
If you have an extruder installed on the vertical pillar, remove it now.
-
Next, unfasten the bolts connecting the pillar to the support bracket at the top of the pillar.
-
Remove the the motor bolts at the bottom of the pillar.
-
The pillar should now come free.

-
Use a 2mm metal drill to create 3 holes on either side of the platform.
-
Place one of the 40cm rails on the platform, 4mm +/-1mm from the edge.
-
Use a pencil to mark out where you are going to drill.
-
Secure the rail as shown with three M2 x 10mm bolts and M2 Nyloc Nuts
-
Be very careful with the carriage, either secure or remove them very carefully. If they fall off and are hit, the ball bearings inside them will escape!

-
Use a 3mm bit to drill three holes into the gantry.
-
The rail should be fitted 5mm from the top edge of the gantry.
-
Secure with M3 x 12mm Cap and M3 Nyloc Nut
-
-
-
Align the thicker 15mm rail to the centre of the pillar and create marks for three holes.
-
Drill three 3mm holes into the pillar.
-
Secure the rail with three M3 x 12mm cap bolts and M3 nyloc nuts.
-
Re-install the z-pillar when done.
-
-
-
Using a soldering iron push the threaded inserts into the 3D printed parts as shown.
-
M4 Threaded Insert
-
Note that the inserts on the Tool Carriage part need to protrude out on the side shown.
