I doubt that it'll really have killer features.

You'll most likely be able to exchange the 2 Hotend-Toolhead for a Laser-Hotend, it'll have a heated AMS, it may have a vinyl-cutter head.

I don't really think I'd want to Laser on my heated bed, or cut on it either. The Fumes from lasering will impact durability of anything in the printer, without really lots of ventilation it will produce lots of dust (well, ash).
Cutting on the same head is weird, as a cutter needs to resist a bit or cutting force.

The dual-nozzle-design is interesting, but I think it's still vastly inferior to multiple toolheads, with anything over 2 materials there is still cutting required. Depending on how they solved the issue with feeding the two hotends, I'm not sure how there won't be quite a bit of added complexity for loading the AMS, where you have to think which head needs which filament.
Using a single extruder gear for both hotends also increases chances and risk of cross-contamination. I've never had a printer who didn't occasionally chew filament.
Moving the Hotends on linear rails, having a mechanical drop-stopper on the hotend all increase complexity, I'm not sure how bad blob of dooms will get here.

If they use their touted servo-design actually on the corexy kinematics, that will be interesting, because conventional wisdom says it doesn't really improve 3d-printing performance. At least not until you get to ridiculous builds (think minuteman)

Cost will be interesting, as apparently the H2D was touted to "be above current X1 line", if that were to include X1E and the $2500 price tag it would be... rather expensive.
But even when it's "just" more expensive than the X1C at $1200/$1450, coming to... idk, $1500 in it's bare configuration, that's rather big chunk of change for a hobbyist. And they will (hopefully) have lost lots of enthusiasts with their firmware-stunt.

Something kinda cool that could theoretically be done would be print smoothing with the laser. Print it, change the tool, laser (at least) the stairstepping on top away.

I've had partial clogs that manifest like that.
Cold pulls (several) ended up resolving my issue.

my best explanation was, that there was some debris in the nozzle, which would sometimes (nearly) seal the nozzle, and at other times be retracted with the filament, get stuck somewhere else and filament flows freely.

The whole idea is they should be safer than us at driving. It only takes fog (or a painted wall) to conclude that won’t be achieved with cameras only.

Well, I do still think that cameras could reach "superhuman" levels of safety.
(very dense) Fog makes the cameras useless, A self driving car would have to slow way down / shut itself off. If they are part of a variety of inputs they drop out as well, reducing the available information. How would you handle that then? If that would have to drop out/slow down as much, ~~you gain nothing again~~ /e: my original interpretation is obviously wrong, you get the additional information whenever the environment permits.
And for the painted wall. Cameras should be able to detect that. It's just that Tesla presumably hasn't implemented defenses against active attacks yet.

You had a lot of hands in this paragraph. 😀
I like to keep spares on me.

I’m exceptionally doubtful that the related costs were anywhere near this number.

cost has been developing rapidly. Pretty sure several years ago (about when tesla first started announcing to be ready in a year or two) it was in the tens of thousands. But you're right, more current estimations seem to be more in the range of $500-2000 per unit, and 0-4 units per car.

it’s inconceivable to me that cameras only could ever be as safe as having a variety of inputs.
Well, diverse sensors always reduce the chance of confident misinterpretation.
But they also mean you can't "do one thing, and do it well", as now you have to do 2-4 things (camera, lidar, radar, sonar) well. If one were to get to the point where you have either one really good data-source, or four really shitty ones, it becomes conceivable to me.

From what I remember there is distressingly little oversight for allowing self-driving-cars on the road, as long as the Company is willing to be on the hook for accidents.

well, Apollo was not part of the Saturn program, was it?
Rocket did fine, even during Apollo 13 it wasn't the Saturn.

They talk about the safety record of Saturn rockets without mentioning that using those isn’t currently possible

And that, at least from my memory, multiple people in the Saturn Program considered it to have been extremely good luck to not have had a failure which led to deaths.

Judging by the fact that he has an imagineer-video out (effectively) at the same time as the space-mountain mapping, I'd expect that Disney was fully aware of what he was doing, and the whole sneaky-thing was just to make it more appealing to viewers.

They do.

But "all self driving cars" are practically only from waymo.
Level 4 Autonomy is the point at which it's not required that a human can intercede at any moment, and as such has to be actively paying attention and be sober.
Tesla is not there yet.

On the other hand, this is an active attack against the technology.
Mirrors or any super-absorber (possibly vantablack or similar) would fuck up LIDAR. Which is a good reason for diversifying the Sensors.

On the other hand I can understand Tesla going "Humans use visible light only, in principle that has to be sufficient for a self driving car as well", because, in principle I agree. In practice... well, while this seems much more click-bait than an actual issue for a self-driving taxi, diversifying your Input chain makes a lot of sense in my book. On the other hand, if it would cost me 20k more down the road, and Cameras would reach the same safety, I'd be a bit pissed.

Shining3D also makes professional-level scanners that cost as much as a car, so I banked on them putting some of that expertise into their consumer models and went with the Einstar.

Seems like you were correct.

hardware is fine. If you're not experienced the 3000km will fuck you though. Stuff will arise where you will need to get at it.

I've been using two laptops als "servers" for years.
well, the first one died after about 6 years of use.
But I can get at them reasonably.

[–] [email protected] 5 points 2 months ago* (last edited 2 months ago) (1 children)

that is more editing and good lighting.
there are always layer lines.

Depending on you I would recommend
Voron (DIY, will take about a week to build and a week to tune),
Prusa (depends on your preference, assemble yourself or built, depending on required time a mk4s with mmu3, or the core one which will take several months to get to you, and the mmu3 later when it will become compatible)
Qidi (cheap, chinese, will likely work decent after some tuning)

[–] [email protected] 2 points 2 months ago

there isn't a "best" really. Depends on your wants/needs.

for true Openness, I don't think anything beats a Voron.
Prusa is great (good track record, good support, Hardware is not open anymore though, can work out of the box), but expensive.
plenty of others get you something largely decent for low prices (qidi, creality for example) but long term support seems likely to lack, and there are always reports of some issues for some and great results for others.

The Security argument doesn't hold water when you're pushed toward the cloud use for transmitting data over your own network cable would suffice.

Define APIs and API keys (local and cloud).
Instant safe communication, local and/or cloud.

 

tl;dr: "Fuck You, we're right, but here's a crumb from the table" but in PR-speak.

There'll be a Lan-Mode (still requiring Bambu Connect), and a Dev-Mode (which will continue MQTT, live steam and FTP).

The Writing continues to be on the wall.

 

Apparently some group has broken Bambus encryption.

Apparently, as he claims, the logs reveal not only (further) licensing issues with Bambu, they also apparently send the complete Model you want to print to Bambu, which would be a huge issue for any companies using them.

What do you think?
Anyone ever checked on the size of the logs? Does it make sense that they actually send the whole Model?

/e: clarification, apparently the logs do not get sent to bambu by default on every print (even while in LAN-Mode) as it can be understood here, but all of this info is in the logs you can manually choose to send to Bambu (i.e. in the case of an issue with a print(/er) bambu is reasonably likely to ask for this).

 

I've just found this Optimus Gen 2 demo, and I thought it's quite interesting.

The Hands are surreal, the gait is still weird, but from what I understand it's a lot easier to walk without an outstretched joint in robotics (avoiding singularity in the kinematics).

Very curious to see if they just did the "easy" 0-80% and will kinda get stuck here, or will keep improving rapidly.

Really looks like it may be used on assembly lines in another year or so. But this is promotion, so looking like that is kinda the point.

what do we think the runtime of these is untethered?
If they have a full AI stack in them, won't they need quite a bit of compute power?

Hey there.

All my scam-alarmbells are ringing, but I'd like to have a little perspective because I never got into trading with crypto at all.

A friend of mine apparently put about $70k in different crypto into masscoin.vip Then there seem to have been some hijinx with mistyped adresses, and talks with support later, masscoin.vip representatives tell my friend, that they need to fork over another 10% of their holdings, so another $7k, to validate their account or something.

This has to be a scam, right? The Money is gone, and since it was put in via crypto there is no way to recover it?
