I am still waiting for OpenRail to be back in stock and I will make my own extrusions for the y axis while I wait for the new ones. I just need 30inch in either direction to make my parts.

Oh, I don't really have space (or justification?) for a 48"x48" machine anyways. I've really just been hoping to double the length of one of my axes. Although it sounds kind of fascinating. I suppose if a 48"x48" upgrade was $1000, maybe I'd feel better about the price, consider what I could do with the extra capacity, and try to find the space. If that's what it takes to double my Y axis, though, I'd be disappointed. That's sort of why I said I'd been waiting to see what the kits actually consisted of. I've got a lot of irons in the fire at the moment, so not in any rush... I'm just unjustifiably eager, and hungry for more info. :-)

I'll be disappointed too. Machine I'm looking for is expanding X-axis with one new extrusion and a belt, plus cable extension cords. The under carriage could be cut and bolted to new flat steel to expand. So in theory a single axis expansion cost should be 'containable'.

As for the rigid table issues, something similar to this system (https://www.youtube.com/watch?v=KnNi6Tpp-ac) could be used to give torsional stability. I'm already using this design under my SO3 as deep as the machine and long enough to fit the expanded 48inch in X-axis machine I'd planned for.

Hopefully expansion kits will come in several mixes.

This would be a nice potential synergy for the Sparkfun partnership — let them sell parts, incl. extrusion in longer lengths.

So, a few things about that:

A. Synergy is not a "made-up dot com word": https://en.wikipedia.org/wiki/Synergy#History
In 1896, Henri Mazel applied the term "synergy" to social psychology by writing La synergie sociale, in which he argued that Darwinian theory failed to account for "social synergy" or "social love", a collective evolutionary drive. The highest civilizations were the work not only of the elite but of the masses too; those masses must be led, however, because the crowd, a feminine and unconscious force, cannot distinguish between good and evil.
2. Synergy is not the same as cooperation. They mean different things.

D. All words are "made-up". :)

Maybe my issue with the word is that it is used incorrectly in most cases.... Working for software companies around the dot com era I've heard it used for everything but what Mr. Menzel was thinking about when he coined the word. :oops:


All words are made up.... and the point don't count :ugeek:

(where are points B and C?)

@twforeman, I agree with your points A, 2, and D, but I find the Wikipedia quote (which probably paraphrases Henri Mazel) doubly repellent: firstly, the idea that Darwin has anything to do with how society works, or how it should work, is false (and abhorrent, because it's been abused that way to justify eugenics and other evils -- the whole point is that, as a society, we're better than "nature red in tooth and claw") -- there's no need to argue that Darwinian theory ignores "social synergy", because it doesn't apply to societies, period. And secondly, it uses "feminine" as a derogatory epithet. Ew.

Wooh... all this and all we wanted was a few extrusions...

I priced out some openrail and some 80/20 extrusion. 2 1500mm sections would only be about 120 bucks. If i wasn't focused on my laser i would give it a whirl. Once my laser is up and fully functional maybe Edward will have the longer extrusions available and i will have to make the drive to Chicago to get them!!!

I'm pretty keen on an upgrade too, I've got the hang of this bad boy but would love a 4x4' work area... not looking forward to postage to Australia though :shock:
