Fit the magnets in the bed arms and drop the Countersink Screws M3x20 through the magnets and printed parts
-
Fasten the magnets by attaching 2x M3 hex nuts from the bottom of each arm
-
-
-
Each bed_arm takes 2 3mm x 35mm dowels. Gently press or twist the dowels into the holes.
-
-
-
Put the M5 hex nuts into the blocks
-
Fasten the blocks by threading Cap Head Screws M5x35 through the plastic parts
-
-
-
Thread each arm on its respective lead screw (loosening the lead screw in it's coupler might help here)
-
Attach the arms to the MGN carriages with 4x Cap Head Screws M3x20 for each arm
-
-
-
Thread the Cap Head Screws M3x30 through the bed_cable_relef part and attach it to the arm part
-
Insert the M3 hex nuts in the slots on the other side and pull them in by screwing in the screws - this will ensure those are aligned properly and not bind in the part.
-
-
-
The goal here is to ensure the lead screws are paralel to their rails. This step is very important to ensure proper print quality. The Z motor mounts were designed to allow some adjustment - we'll take advantage of that here
-
If needed loosen the 4 screws holding the front motor mounts and move the motor around to achieve proper lead screw alignment
-
Ensure the alignment of the back lead screw by allowing the mount to move in X with the M5 screws
-
Alignment in Y of the back lead can be achieved by loosening of the M3 screws holding the motor to the mount
-
If you did not already, at this point make sure to fasten all screws in the MGN rails
-
-
-
To prevent scratches, the bed plate is shipped with a protective film on both sides.
-
Gently peel off the protective film.
-
-
-
Attach the Countersink M5x16 screws to the 12mm balls through the 6mm spacers
-
-
-
You may want to wipe the surface of the bed with >90% alcohol to make sure you are attaching to a clean surface
-
Peel off the sticker's protective layer from the pad and glue it to the bottom of the bed plate
-
The extra hole is there for a ground wire
-
-
-
Place the assembled bed on the bed arms
-
Secure the bed wires to the bed_cable_relief part with zip ties

There appear to be some proprietary parts. Any way you folks would consider selling say the bed, magnets, and balls? I'd love to add this set up to my custom printer.
The bed is just a standard aluminum tooling plate. They are pretty inexpensive, and available pretty much any place in the world that has industry. Just search the internet for “cast aluminum tooling plate.” Mic6 is the tradename for the Alcoa version (this is the industry standard, buy this if you do not trust yourself to buy something different), but any plate from a reputable supplier will probably be just as good provided it is advertised as being stable. The balls are just threaded steel balls, nothing special, same for the magnets.
