Just curious, how much additional error is introduced in each macrocreation iteration? Will it scale up at the same rate, or will we be seeing exponential increases? nicholas.seward Wrote:...

If the bed were on a turntable, you could maximize the 3:4 design?

@nicholas LOL my math is a bit off. At these rate, it won't be too long we need carbon nanotube structures. Turntable ? That's look like 3D scanner. jason.fisher Wrote:...

@BloodBlight: so, a completely gear-driven design? That could add rigidity/stability, sure. Why do you feel it would be "backlash free"? I would think switching from belts/lines to gears would tend to...

I need to hack a 3D printer together so I can make prototype bearingless Simpson's on the cheap. 3D printer part quote: This past weekend I got a quote for the upper arm using makeXYZ.com. It was way...

That is a shame that the fee model for 3D printing doesn't promote good design. Low infill is vastly superior to shelled parts. I personally design with the simplest part that does the job and throw...

Those on-line printing services are good, but way expensive. I think they worth the cost only in very special items, such as a silver or gold personalized ring or a very rare material like titanium....

Herringbone belts might mesh nicely on the faces. Don't have any to test with though. 3 offset laser cut gears face to face would work nice though.

I'm building a wooden H.A.I.B. version of Simpson (made from discarded items), I started a few days ago :) Today I was at the hardware store looking for a timing belt to replace the herringbone gear....

One other note. The arms still need to be geared together as they are in this design: [forums.reprap.org] So there would also be some play in those gears (so potential backlash from that).

Nicholas, Watching your very cool video, I heard you mention that 5mm bolts are hard to get here in the US. If you have an Ace Hardware store near you, they might have a good supply. I have one about...

@JohnSL: I have tried ACE and every other place in town. They have M5 bolts but not much selection and they are way over priced. I have found them to be up to 10x the price of McMaster Carr. In this...

Hmmm... I will think about part count. Ether using loner gears and a clip at the end (one printed part and a screw is all it would be) would be easy, but I think a I can come up with an easy and low...
