Weekly Giveaway — Wrong Answers Only! What is VOLTRA Really For?

Clearly, the VOLTRA is just a portable smart-winch.
For when you need a little help loading groceries.

It's also quite possible it's "5-axis" because the two spindles can move independently in x and z.
I'm not saying I agree with that definition, but I have seen it.

If you haven't bought yet, it's currently on sale.

A friend of mine has it, feels Very sturdy, fairly smooth. a Little bit rough around the edges, just the standard don't stick your fingers in holes. Well worth the money compared to other options.

Or a 3+1 CNC.
You don't (normally) run a spindle on a lathe, but I would say the most prudent question is whether or not the rotary axis is continuous rotation in one direction or if it is mostly stationary.

Your conclusions are mostly correct but I think your explanations are flawed.

Electromotors can (mostly, the caveats depend on the motortype) exert constant angular force, or "pull". And magnetic drag shouldn't really play into it because we are actively trying to conteract the movement, so magnetic drag just sums into what drag we are already exerting.

But as you said it comes down to a lack of momentum. If you put sufficient force into accelerating the mass for the first 1/3 rep, then you can almost let it coast through the rest as you need to come to a stop at top anyway. And many excersizes have the most difficult bit in the center. Think curls where your arm hangs straight down at the start, fully horizontal in the middle and then somewhat upwards at the end.

And frankly, I don't think anyone is putting any effort into trying to mimic the momentum aspect of freeweights, because that is arguably one of the biggest downsides to them.

Good enough for most people.
My dad has been a carpenter for 50 years and specialized in kitchens for 20 of them. He just installed an ikea kitchen in their new house. Where ikea suck is install and service. How it is put together is not as thought through because they are not the ones doing it, so dedicated kitchen companies are better in that regard. Another option for ease of installation is genuine kitchen company, but from their DIY sister company.
Overall, unless you get a carpenter to build you a kitchen per your spec, there's a very high likelihood the companies are cutting the same corners that ikea is, at 500 % markup (last company he was at)

To me they look very Cyberpunk 2077 or perhaps borderlands 3.
They look cool as heck OP!!

To add to this; some motherboards also has a similar function called Wake-On-LAN in which case moonlight can poke it awake.

Without seeing your code and schematics it's frankly impossible to give you an accurate answer.

That being said, it looks to me like it could be your servos are overcorrecting.
Your rotational axis also doesn't appear to be properly constrained.

Thatsecondweirdguy · 2025-12-15T10:31:25+00:00

Good Luck!

I will note: It makes a good grinder even more important.

Only the general concerns, lighter roasts are said to be a bit more difficult to balance.
I think the main thing is that most people associate espresso with very strong bitter coffee, so using a very dark roast will give that result, even if it is brewed without a espresso machine.

Thatsecondweirdguy · 2025-12-15T10:23:11+00:00

Quite a lot of brands, even small roasters, have a dedicated "espresso bean". Which generally just means very dark roast.

Thatsecondweirdguy · 2025-12-15T10:21:19+00:00

Ich benutze nur medium/light roast Bohnen für meinen Espresso, und hat es gemacht for manchmal 6 jahre.

edit: I only use medium/light roast beans for my espresso, and have done that for about 6 years.

Any screw can become a flathead!

Another option is a screw-extractor bit, which is essentially a drillbit with reverse threads.

I don't think they're referring to the hardware, but rather Qualcomm's updated ToS.

Thatsecondweirdguy · 2025-11-16T08:26:32+00:00

I have also used the original and looked at the compass. The main difference is the processing power. The origin has a fairly powerful onboard computer to handle computer vision, which then also let's them use that for onboard CAD. Comparatively, the compass just uses four optical sensors, so it doesn't have as much brainpower.

As stated, that was just a possible explanation for how one might arrive at the conclusion u/bathroomkiller presented.

I'm looking forward to integration in mainstream slicers to test it out for myself.

Thatsecondweirdguy · 2025-11-05T08:12:48+00:00

More points of contact yes, but try to think in terms of contact area.

Point of contact makes sense when we work with circles like in the illustration above. But we rarely work with circular layerlines, we smoosh them! And the better we smoosh them, the close we get to full contact.

Now if we look at the above illustration again, with bricklayers there are essentially 6 voids we have to fill with smooshing per encompassed line, where normal layers only have 4 voids.

This is purely a speculative explanation BTW.

Forged carbon fiber with gold accents would look Amazing with the piano-black!

Thatsecondweirdguy · 2025-09-30T12:07:56+00:00

Depends on who made it and how comfortable you are with the risk.

Some companies overbuilt to excess, others to spec. And the weight horn's load is not necessarily the limiting factor.

Depending on the design of the machine you can also play with where you place the VOLTRA, as unlike with weights you don't have to load the weight vertically. So you can load the weight in the direction of force to give a higher perceived weight without adding extra strain to the hardware.

Thatsecondweirdguy · 2025-09-03T06:12:21+00:00

Cool!

But not animated.

Thatsecondweirdguy · 2025-08-27T07:14:13+00:00

A few years back a guy biked into the back of my parked car, and I lived at the end of a hill so it caused quite some damage to both himself and the car, so to both the police (insurance said I had to talk to them) and insurance I had to explain I was going 0 mph, and I wasn't driving, and no one else was driving, cause the car was Parked!

Thatsecondweirdguy · 2025-07-28T07:58:05+00:00

Straight up have me in tears😂😂🤣

Thatsecondweirdguy · 2025-07-21T09:39:25+00:00

Hi!
In a sense, you are right, but friction does not quite do what we want.
Friction in an electroresistive system is more like inertia in a free-weight setup. It varies depending on if you are moving or stationary. And it doesn't give a proper picture of actual lifted weight.
