gantry

Even as a gantry system, their rendering is naive.

So, I set out on this path to build a beefy CNC gantry machine that could do what I needed.

The only constraint on the gantry in the direction of the long slide are two sheets of 1/4" mdf.

The gantry system lets us program 3D space however we want it, and that is remarkable.

Any gantry based system is going to be a headache from the start because you've got those rails cluttering up the space.

Vat of pancake batter + z axis actuator + laser on the gantry = 3D pancakes

However, a human operator is not like a gantry-style CNC router, they cannot simply "fly" over the work area.

They've completed a new gantry/launch tower for their next generation of rockets which will be close to or bigger than the Saturn V. Several of the launch pads have been completely retrofitted.

"Out on the street, suspended with the speed-adaptive air suspension, the Model S has an utterly unshakable, gantry-like vibe to it, even with the big meats in the wheel wells.

I been trying to think about this from a different angle and have been trying to work out how long you could make a self-supporting fuel and oxygen line by putting a lightweight triangular gantry with three small adjustable rocket engines and a fuel pump every hundred meters or so.

I could see the cost/benefit trade-off going that way, after all one of the multi-million dollar tunnel boring machines digging the Chunnel was left entombed [1].That said, I have to wonder if you couldn't use a balloon to extract the digger or even a simple gantry crane over the excavation.
