    • Insert the Lead-Screw-Y further into the channel, and then thread it through both Nut-Blocks on the Y-Carriage-Right.

    • The Nut-Blocks should be loose so their position can be adjusted to allow Lead-Screw-X to thread through.

    • 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

  6. Thrust-Bearings come in 3 parts. Thrust-Bearing-Housing-Washer, Thrust-Bearing-Caged-Roller and Thrust-Bearing-Shaft-Washer The Thrust-Bearing-Housing-Washer and Thrust-Bearing-Shaft-Washer look exactly the same. They are not. We recommend adding a generous amount of bearing Lubricant to the grooved face of both washers.

Very impressed with the quality of the components, excellent instructions, I like the components being in very well labelled bags. I am slowly and meticulously working through getting each part out as I get to them and returning bags to correct boxes when I have finished a section. I suspect I am benefiting from others comments being implemented. Really enjoying the process and so far it all seems to move smoothly and is square to the mm. Here’s to the next stage. Thank you.

Hi Paul,

Thanks for the feedback, that is very good to hear!

I do agree that the labels on the extrusions are very difficult to remove. To date, this is my only criticism of the assembly process which I am enjoying. Thanks to previous contributors who have obviously helped improve the guides.

(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
