That's a purdy truck. I doubt I'll be able to get away with less driving, as I need to transport tools to jobs, and that I cannot do on a floaty thing, bicycle, or afoot. As to locating print heads, the Bambu Labs X1 Carbon has recently incorporated lidar, which is presently limited in that device to accurately siting the first layer of a print. However, I can see that lidar can quickly be extended in utility for such purpose as we discuss. Not being a coder, I will be pretty slow (or more likely remain incapable) to add such functionality, while better minds than mine might well do so with facility. Even a relatively wobbly arm compared to solid cartesian printers might produce accuracy within acceptable limits by using lidar to continually correct print head location. I sure hope someone is already on it, at least.
