-
Prepare 2 x Y-End-Plate in the orientation shown in Image 1, with a M5-Button-Head-Bolt-12mm through each of the 4 bottom holes and a M5-Tee-Nut slightly threaded onto each one.
-
The flat side of the M5-Tee-Nut should be facing the Y-End-Plate.
-
Repeat the above 2 points, but for 2 x Y-End-Plate in the orientation shown Image 2.
-
-
-
Position the two Extrusion-F's on top of the Base-Assembly.
-
Carefully slide the Y-Carriages on the X-Gantry through the Extrusion-F's
-
Adjust the position of each Extrusion-F so the ends are flush with the corners of the Base-Assembly.
-
-
-
At the front right corner of the machine, slide a Y-End-Plate into the two front-facing slots of Extrusion-A.
-
Attach the Y-End-Plate to Extrusion-F using 4 x M5-Button-Head-Bolt-16mm through the non-threaded holes on the Y-End-Plate and into the threaded holes on Extrusion-F.
-
Make sure the side of the Y-End-Plate is flush with the end of Extrusion-A.
-
Then tighten all the M5-Button-Head-Bolt-12mm on the Y-End-Plate.
-
Repeat for the other 3 corners of the machine.
-
-
-
Slide the X-Gantry to the back of the machine as far as it will go.
-
Slightly loosen the 4 x M5-Button-Head-Bolt-12mm on each of the two front Y-End-Plates.
-
Carefully slide the X-Gantry to the front of the machine as far as it will go.
-
Re-tighten the M5-Button-Head-Bolt-12mm loosened in the green point above.
-
Keep the machine at the front and slightly loosen the 4 x M5-Button-Head-Bolt-12mm on each of the two back Y-End-Plates.
-
Carefully slide the X-Gantry to the back of the machine as far as it will go.
-
Re-tighten the M5-Button-Head-Bolt-12mm loosened in the orange point above.
-
-
-
Insert a Lead-Screw-Y through the large 16mm hole on the front right Y-End-Plate so it protrudes into the channel on Extrusion-F roughly 100mm.
-
Slide onto Lead-Screw-Y a Flanged-Radial-Bearing - ->- - Rubber-Bushing - ->- - Clamping-Collar.
-
Insert the Lead-Screw-Y further into the channel, and then thread it through both Nut-Blocks on the Y-Carriage-Right.
-
Once through the Nut-Blocks, slide onto Lead-Screw-Y a Clamping-Collar - ->- - Rubber-Bushing - ->- - Flanged-Radial-Bearing.
-
Thread through Lead-Screw-Y further so it goes through the large 16mm hole on the back right Y-End-Plate. Adjust the Lead-Screw so there is 14mm protruding from the back right Y-End-Plate.
-
Seat the Flanged-Radial-Bearings into the Y-End-Plates, slide the Rubber-Bushing against the Flanged-Radial-Bearings and finally slide the Clamping-Collars so they are against against the Rubber-Bushings. Slightly tighten the Clamping-Collars.
-
Repeat all the above points for the left Y-End-Plates and Y-Carriage-Left
-
-
-
On the Lead-Screw-Y protruding from the front right Y-End-Plate, slide on a Nylon-Shoulder-Washer - ->- - Thrust-Bearing-Housing-Washer - ->- - Thrust-Bearing-Caged-Roller - ->- - Thrust-Bearing-Shaft-Washer
-
The Nylon-Shoulder-Washer seats in the 16mm hole on the Y-End-Plate.
-
The Thrust-Bearing-Caged-Roller seats in the grooves on the Thrust-Bearing washers. Same orientation as before.
-
Finally slide on a Clamping Collar. While pushing the Clamping-Collar against the Thrust-Bearing assembly, tighten the Clamping-Collar.
-
Repeat all the above for the front left Y-End-Plate.
-
-
-
On the Lead-Screw-Y protruding from the back right Y-End-Plate slide on a Nylon-Shoulder-Washer - ->- - Thrust-Bearing-Housing-Washer - ->- - Thrust-Bearing-Caged-Roller - ->- - Thrust-Bearing-Shaft-Washer
-
The Nylon-Shoulder-Washer seats in the 16mm hole on the Y-End-Plate.
-
The Thrust-Bearing-Caged-Roller seats in the grooves on the Thrust-Bearing washers. Same orientation as before.
-
Finally slide on a Flexible-Coupler. While pushing the Flexible-Coupler against the Thrust-Bearing assembly, tighten Flexible-Coupler
-
Repeat all the above for the back left Y-End-Plate.
-
-
-
At the front right corner of the machine, an Angle-Corner goes in the corner between Extrusion-A and Extrusion-F.
-
First slide an M5-Tee-Nut into the top slot of Extrusion-A.
-
Use a M5-Button-Head-Bolt-8mm and the previously inserted M5-Tee-Nut to attach it to Extrusion-A.
-
To attach it to Extrusion-F, use a M5-Button-Head-Bolt-8mm and M5-Drop-In-Tee-Nut.
-
M5-Drop-In-Tee-Nuts do not need to slide in from the end.
-
They go in to the slot parallel, when the bolt engages they should spin perpendicular to the slot and bite into the underside of the slot.
-
-
-
Attach a Stepper-Motor to the threaded holes on the back left Y-End-Plate using 4 x M5-Cap-Head-Bolt-50mm and 4 x Aluminium-Spacer-40mms.
-
Once in position, tighten the clamping bolt first, then the grub screw.
-
-
-
Attach an End-Cap to the front left end of Extrusion-A using 2 x M5-Button-Head-Bolt-8mm.
-
Repeat this for the other 3 bare ends of the Extrusion-A's.

Hi Robert,
Just a general comment on the assembly manuals: it’s doable and besides some small typos it is all clear. But if I compare it to the assembly instructions of the Joseph Prusa 3D printer it is not as good. What would save the assembler time and avoid making mistakes would be for instance briefly summerizing which parts, screws, bolts or whatever is needed instead of mentioning this within the assembly instructions, including a small graphic image of the parts. Collecting the parts is time consuming , as the plastic bags are white the side where the description of the content is and transparant on the other side. I noticed in some videos of older machines that you used to use transparent plastic bags labelling it with a sticker. This …… (why limit these comments, I don’t get it…..)……
(second part of my comment, but why require/demand to be signed in, welcome ALL comments)
……….would have been much better and would have saved time. Then…. it would be good to describe the sections a bit more in the overview. Then the extrusion numbering: you have to remove the labels printed on them as all are in the way except the short extrusion D for the Z-axis. Many times I am was wondering where extrusion A, B, E or F actually were. Another issues: the glue of the labels is super hard to remove, even with alcohol or aceton; you really have to use a label glue dissolvent to remove it.
But my machine Z+ 1500x1500 is no fully assumbled apart from the table below it and it all seems to work fine sofar. It’s for me the first time I do this, although my experience with 3D printers and Fusion360 comes in handy as it is not really so far apart.

Hi Mark,
Thanks for your comment. The maximum comment length is set by Dozuki (The software behind learn.ooznest.co.uk) and we have no control over it I am afraid.
The same applies to having to be logged in to comment (On Prusa manuals you need to be logged into to comment also)
I believe Prusa uses the same software for their guides.
I have looked at Prusa guides and can see they have steps about collecting the parts, which is a good idea, and something we can think about adding.
Did you see our Box Cheat Sheet here to help locate the parts: https://ooznest.co.uk/wp-content/uploads...
For the extrusion, the labels should have been peelable, I have raised this as an issue, as to why they are not peelable, as I know we have specific labels for the extrusions that should come off easily. My apologies they were difficult to get off in your case.
Thanks for all your other points, they have been noted.
Robert
