One of those cnc videos you just have to watch

[EddyCurrent]

I like it.

I like it.

Ermm. . . It's just Bling.!!. . . Nothing more than an over complicated engraving machine and not a very strong one at that.! . . . . Probably paint you a nice picture thou or pick n mix machine. .:stupid:

Well they said it was just a desktop, but it's how they made it modular that I like plus the build is easy. Everyone doesn't want to cut aluminium with a water cooled spindle. :triumphant:

Some of those geometries are used for 3D printing, where there is no load worth talking about on the tool platform. I've never quite understood why this kind of mechanism is used, but I'm sure that there are reasons. Something to do with print area compared with overall footprint, maybe? Most interesting aspect is working out the kinematics of the motion control, but clearly that's already been done.

Main reason for that kind of setup is to get 5 axis movement with only 3 motors.
I have seen videos of big machines using this kind of setup, as when done right it works well.

The motion control is out there. I know there was a 6 support version done using a KFlop by some university, as it came up on the dynomotion support group a while ago.

I saw this a few weeks ago now and liked it as well. Exactly, this is a demonstration of a modular device that is computer numerically controlled, the limitations are ones imagination. I've also seen a simple mobile system like this one, it was being used for on site work both horizontally and vertically.

If executed properly the hexapod design is excellent for making a strong '5-axis' machine with minimal material, since the frame is based on triangles so inherently strong.

Yeah, just use Linuxcnc:

It's a very tempting project...

[JAZZCNC]

Just to be clear.!! . . . I wasn't calling Hexapods Bling or weak I was calling THIS ONE Blingy and Weak. Personaly I think Hexapods are awesome and the speed they can work at is unreal.!

First one I saw many many years ago was at Warwick university, sculpting full size car bodies out of huge blocks of foam.

Talking of Hexapods I came across this on YouTube just need to build one that makes tea and sweeps up the workshop LOL

As it happens it's the first time this type of design has come to my attention and as Jonathan says it's a tempting project, maybe I set my sights too low in the beginning ?

lol, indeed !

what about simply offering the snazzy box for sale flat-packed, I'd buy one
