Best I can find in Canada is in BC. I think you could get longer distances in a few other provinces, but the issue is a lack of roads/destinations in the northern corners, haha.

That sounds like a problem from using too small of a drive. Every torque curve I’ve seen for brushless DC or AC servos is constant torque from 0 to about 75% rated RPM, and then starts to drop off.
Well, that’s why you use a proper servo drive. Yes, technically they oscillate at standstill, but it’s so little it literally does not matter. Closed loop servo control is a solved problem unless you’re trying to implement it yourself.
I don’t know why you’re getting down voted. You’re correct, steppers are used due to cost.
I disagree with all your points. What kind of servos are you talking about?
BLDC and AC servos maintain full torque at stop too, and have about 2-3× the torque of a stepper of similar size.
The only way a stepper can rival a servo for precision is with a high degree of microstepping, which is far from guaranteed positioning with open loop control.
I haven’t directly compared response time between steppers and servos, but I would be extremely surprised if there’s a significant enough difference to worry about. Most servo-controlled machines are larger and so are designed to accelerate slower than a printer, if that’s what you mean. This is intentional because inertia is a thing you have to worry about, not because the servo reacts to command changes slowly.
There are valid reasons steppers are used on printers, but it’s not because they have superior performance.
Cost is the short version, yes.
I don’t know what kind of servos everyone here is talking about that are less precise than open loop steppers. Low quality hobbyist stuff, I guess? Proper servo motors & drives are the standard for good reason for robotics, industrial CNC machines, and pretty much everything else that needs powerful motors with high precision. Much higher power density, higher RPM (good for increasing torque with a gearbox), equivalent or better precision, plus closed loop control is a huge capability and safety gain.
That said, good, industrial quality servo motors are 1) expensive and 2) aren’t made in small enough sizes to be comparable to the steppers on most 3D printers. Even the smallest industrial servo + drive I’ve seen is about 5x as big as the steppers on a personal 3D printer and costs $800ish. Obviously, both are deal breakers for a personal 3D printer.
3D printers are a fairly ideal application for steppers. The moving parts are small and light, meaning you both don’t need a large motor and the danger of slippage is lower. Plus, steppers are cheap.
NFTs do not solve the problem of proof of ownership. Nor can they. If someone steals it from you - whether by trickery, force, or any other means - it’s just as lost to you as any other stolen thing, digital or physical. (Not to touch on the fact that NFTs to date have just been URLs to web hosted media, i.e. ridiculously non-unique and insecure.)
Also, your whole paragraph about theoretical NFT replacement for DRM is just describing a different kind of DRM.
Agreed. Don’t make a threat - just make the GDPR complaint. Inform the company if you want. How many times have you remembered to follow up on one of those threats to see if you should still make a complaint?
It’s not infantilization. These bills are designed to prevent “one more hoop” design by the company to make it too annoying to unsubscribe. Your position assumes good faith behaviour by the company with the newsletter. That is absolutely not a given.
Lol, then they would have to demonstrate that there were damages. The worst a TOS violation will get you is a ban.
It’s more because of the temperature differential. The more difference between the temperature of two objects, the faster they change temperature. A radiator with 50 degree water is ~30 degrees warmer than the room (or 80+ degrees for a steam rad), while cold water is going to be 10-15 degrees cooler than the room. Any colder and you need to use not-water so it doesn’t freeze. Condensation or frost is also a big concern to avoid property damage.
Meanwhile the C-suite are getting record compensation and stock buybacks. There is no “budget shortfall”, it’s just typical greed at the top that’s hoping the rank and file will swallow it.
I think OP is conflating the amount that a YT channel sees per ad vs the amount that YT would keep. These are not the same thing.
Plus, YT gets their share of every single ad seen every day. The economy of scale obviously is paying off.
It’s broken now? I’d say that’s a bold assumption that it ever worked in the first place.
Edit: to be clear, I mean that it is and always has been an impossible problem. The only reason it ever worked is because some broker company wanted it as a feature, not because anything compelled them to give original artists a cut. And that’s before you consider the question, “but how do you know the NFT was made by the original artist?”
Do you think every paper writer would comply? Do you think that the actually problematic writers, like those cutting so many corners that they directly paste ChatGPT results into their paper, would comply?
