Nearly ready to print! Needs glass for the bed, endstops and a hot-end.
you made a 3d printer by youself.
thats amazing !
i no little about this area, but extremely interest in it.
can u tell me,where i can find some fundamental article on it?
That looks really nice!
I’ve got two questions about the Ingentis, though:
a) What are you using for linear bearings/bushings?
b) Does the bed platform rock back and forth? Both Makerbot and Ultimaker pre-tension their Z bearings with the moment from the platform’s weight - i’d expect the inevitable lash in the bearings to create a seesaw-like rocking motion when moved up and down in your design.
@Thomas_Sanladerer I never thought about the radial preloading of the z bearings. I’m assuming Tim used igus or other plain bearings for x and y as it has to show axial rotation, but I’ll let him speak to the z.
If you use linear ball bearings, there really isn’t too much slop if any. Generally the Preload prevents radial deflection under load. But that still may pose issue if the bed isn’t 100% weight balanced at all times, which it will never be. I’m interested in that as well since I’m looking to copy his design
@Thomas_Sanladerer
a) Bronze bushings for the x/y ends and carriage, LM10UU for the Z.
b) there is a leeetle bit of movement in the Z - maybe 1/2 a mm at the furthest point from centre; Mildly concerning but I figure I’ll do some prints and see if there are any discernible artefacts. The weight of the bed prohibits a cantilever approach a la makerbot/ultimaker but there are a few possibilities for minimising any see-saw action.
You could use an idler between 2 of the lm10uu on each rod to put radial load on the linear bearings. Adds some complexity to your very clean design, but not too bad
Idler could be a 608 or similar
I was thinking of just putting a bit of depleted uranium on one end of the bed to give it some pre-loading. You can buy depleted Uranium from AliExpress right?
The bed doesn’t have to be fully cantilevered like Makerbot and Ultimaker. Just shift the belts and rods far enough to one side that the load will always be on the same side of the bed’s support. Maybe a 20% offset from center?
@Tim_Rastall How did you resolve the problem of the spectra line cutting thru the printed spools
@Mike_Smith more infill and I made some changes to the design. The current versions seem fine.
Very nice looking build @Tim_Rastall looks pretty familiar to me too 
My ultimake type printer is nearly finished!

Aliexpress just sells normal uranium, but it depletes by the time it reaches your house
@James_Jones_CubeSpaw Wow, that is a lot of tslot! Are you blogging your progress somewhere, it looks like you’re building a factory 
@Eric_Moy well played sir
@Tim_Rastall Thats 'cause I’m building an open source factory!! there is some bloggery on the cubespawn site, some in the wiki and of course the picasa stuff… its big, open source, automation FTW! still kindof haphazardly documented…
