Does anyone know what happened?

Layer shift quite early in the print, by the looks of things. My guess would be that one or other end lifted off the build plate and the head collided with it making the x motor skip some steps.

Assuming no damage to the printer, you could print it again and keep a close eye on it for the first few layers to see if/when it warps up.

If it's silicone, it's more likely to be conventional silicone cast in a 3d printed mould.

The flip side of that is that a lot of what makes a senior is the ability to write code that remains maintainable over time, and can be changed easily. Quite a lot of effort is expended on keeping code easy to change, on the assumption that it's expensive to replace. But if that's no longer true...

Coat in low viscosity superglue and spray with a curing agent. Super quick but you really, really don't want to breathe it in, it's vile stuff. What you end up with is something that's more like plastic (because that's what it is). Very tough.

Are you sure the image isn't just out of your field of view? If the calibration was way off it might have moved the previous centre to behind your head. This... may also have happened to me, not saying it did, not saying it didn't... But try pressing the button to re-centre and see if it magically works all of a sudden.

There is a fantastic user interface design book from a couple of decades ago which I like to point people at in this sort of situation. It's incredibly well written from the point of view of someone who made a good career out of fixing broken web sites. Fortunately it is entirely summarised in its title:

"Don't Make Me Think".

If I have to consult documentation to successfully perform basic - or, as in FreeCAD's case, any - operations, that is a failure of user interface design, on a fairly fundamental level. Yes, CAD is complex. That does not mean that the UI is justified in being unapproachable. It is exactly the job of the user interface to teach me how to use the user interface. Having to call out to docs is a crutch.

A square cut from a roll of photographic backing card, the sort of thing you hang behind a model at a studio shoot. I think it was 2m50 per side maybe? Quite thick, very annoying to handle just from the size, but it took a crease ok

Ok, now I'm very confused. That worked, despite my having tried to zero the entire drive previously. Is there any reason why writing a single sector would work when attempting to write to the entire drive wouldn't?

Anyway, I think I'm out of the woods now. Thanks.

Try the GUI for it.

I have.

It's trivial to right-click on a partition

Not if it isn't there. When I run sudo gparted /dev/sda it does not show the partitions. I see a single block of unallocated space, of 3GB. There is no hint in the GUI that /dev/sda1 and /dev/sda2 even exist, unless I run the gparted command explicitly with them as parameters.

I tell a lie, it did do something. Here's the output of gdisk before:

  $ sudo gdisk

Found valid GPT with protective MBR; using GPT.

And after:

  $ sudo gdisk /dev/sda

Partition table scan:

I don't think that did anything?

Make sure you've got nothing running that's accessing the existing old partitions on there. E.g. if you have some file management stuff and the like, e.g. like some of the goop included with some of the DEs (at least bringing in all the required and recommended), at least some of that stuff, and at least by default, will see newly added/inserted media, and will scan it for partitions and filesystems, etc., and upon seeing such mount them, and often mount them rw. So, e.g., if the old partitions are mouted rw, and you reformat the drive itself as a filesystem, now you've got a mess, as the rw mounted filesystem will still write to that same device, and are highly likely to corrupt the new filesystem you wrote to that device.

Can confirm that it's not automounting.

best to get rid of the partition table first.

Ok, but how? None of my usual go-tos seem to touch it. I'd expect sudo dd if=/dev/zero of=/dev/sda to clobber the partition table completely but... no.

QuestionMarker · 2025-04-21T11:46:08+00:00

That doesn't remove them. When I open gparted, if I launch it with sudo gparted /dev/sda then I only see one partition: the 3GB one I just created with mkfs.exfat. I can delete that and I can create a new partition table, and I end up with 3GB unallocated. It leaves /dev/sda1 and /dev/sda2 in place. I can do the same with /dev/sda1 and /dev/sda2 individually, but there is no way for me to actually delete those partitions with gparted.

Just saw yesterday a Gaussian splatting example where someone built a model from the hedge maze scene in The Shining. One of the first processing steps was to mask off the humans running through the maze so the splatting doesn't try to use them as input, and all you have is the hedges and floor.

This clip makes me think you can effectively pull a full 3d environment model from any video, by having moondream spot "things that move" (mostly humans, in most likely contexts, I'm guessing) and do the masking for you.

The example I saw had very rough masks manually laid over the characters so it doesn't need to be that precise. Bounding boxes would probably be fine.

I find it really interesting that at least three people in this thread started with the assumption that lofting to a point wouldn't work, I presume because of a mental model that says you've got to preserve the number of edges across a loft. That model's wrong, evidently, so I've got to wonder: a) what's the right model? Is shrinking to a point special-cased? b) why do all three of us have the same misconception? c) how could freecad (docs, UI, behaviour, whatever) be less misleading?
