Just a short update. Of course my cameras battery decided to be empty, so no pictures today.

I fixed the naming to an " OK it is not an altar" level. This printer is for test and learning to begin with. The fixes went OK, but could have been much better.
This means that the portal and carrier for the X and Z axis is finally secured to the base.
All structural plastic parts are cleaned up and just waiting for assembly.
Next up is to cut the threaded and smooth rods for the Y axis motion and begin assembly, and to cut out the ply for the Y carrier. I will use the heatbed as template this first try before introducing any changes.
picclock,Interesting things you mention about the Y axis table weight. I will weigh my setup once compiled all together, I will use a 12mm ply board instead of your alu plate. As said earlier, I also look into making a few lightening holes in the ply board as it is mainly used to carry the heatbed and glass plate.
nrml, Interesting to read about your experiences and the way you will go for the nest build. I notice that you are very suspicious about the cheap linear LM8UU bearings, and smooth rods as a concept. On my part I have had experiences with that type of movements way back in time when I was working with packaging machinery. There was no problem with linear bearings and rods then - but I suppose they were of another quality. Will get back to that later.
When it comes to lubrication I will use the same silicon grease as I have used for my lathe and mill, namely ordinary car wheel bearing grease, good specs and copes well with both heat and speed.
As for the Z motion using M5 threaded rod, I think there is quite a difference in precision between the ordinary galvanized stuff and the stainless ones. The stainless are much nicer in both finish and movement as far as I can tell, and nearly no sloppiness either.
Will be interesting to read your build log once your bits have arrived.
No problem with side-tracking my thread.
