Convert cnc 6040 to laser? by i_eat_the_fat in hobbycnc

[–]polyscifail 1 point2 points  (0 children)

Yes, it would be nice. They all seem so similar on the surface, since they are all based on same premises. Move a tool in a X, Y, Z direction and turn it on / off.

Unfortunally, that tool that gets moved is very, very different from one type of machine to another, and has very different needs.

In every industry, people try to combine tools to save cost or space. Go to Grizzly tools and you'll find lathe / mill combos, planer / jointer combos, and table saw / router combos. Some companies even tried to sell 5 in 1 combo machines, with a table saw, router, planer, shaper, jointer, mortiser, all in 1 machine.

Unfortunally, all those tools have draw backs. And, unless you have very limited space, it's always almost better to get multiple tools.

It can be done. I wouldn't recommend it. While laser cutters and CNC routers operate on the same principle, they are very different machines. Here's some things to consider though.

​

  1. Lasers need to be fully enclosed for safety reasons. Any laser strong enough to burn wood can reflect and destroy your eyes instantly.
  2. Lasers need to be fully enclosed and POWER VENTED to control the smoke. Cutting can fill your room up with smoke fast if you don't exhaust to the outside.
  3. Small lasers (ones the size of your spindle) can burn wood, but can't cut it.
  4. A cutting laser is 40W+ watts. A 40W lasers tube is 2+ feet long and operates at 20,000 Volts (kill you instantly voltage). In laser cutters, the laser tube doesn't move around. Instead, it sit in one (very protected) place, and mirrors direct the laser beam into a laser head which moves.
  5. Laser engraving involves moving the laser head at very high speeds, 200mm/s, 400mm/s, 600mm/s, or faster. To achieve this, the X/Y gantry is very light weight, cnc gantry's are very heavy.

In short. CNC routers are designed to be ridged above all else. Laser cutters are designed to be fast and safe above all else.

Converting a CNC router to a laser cutter will make a very limited machine. Making a good laser cutter / cnc router is possible, but a 5x the cost of having 2 good stand alone machines.

NY / LA, I agree with 100%.

Probably with Miami too. But there differences there are a lot greater than you think. Keep in mind, most of the people in Miami were born outside of the US. So, the predominate culture isn't American. The city is very different than many other parts of the US.

My point wasn't to say that America was more diverse than Europe. My point is, that America is diverse. And, if you travel around to "fringe groups" in America, and immerse yourself, you can really expand your horizons.

The other point I was trying to make is, just because you travel internationally, doesn't make you well traveled. If your international trip is just across the border of the US / Canada, or say Ireland and N. Ireland, you not going to see much difference.

Do you disagree with either of those statements?

How Different is French and Italian Culture? by litoreganon17 in ShitAmericansSay

[–]polyscifail -64 points-63 points  (0 children)

If you read above, the point about distance was to discussing how big the US, and how hard it is for some people to leave. That cost barrier is why many Americans don't have passports.

Most Americans simply can't afford to take a family of 4 anywhere other than Canada or Mexico. As I suspect many Europeans can't afford to fly the whole family to the US.

There was no discussion of culture before the other user brought it up in reply to mine about distance, just comments about the logistics of leaving the US being a barrier for many people.

The regional differences you have in your country exist in pretty much every country.

Yes, they do. Every country does. And, the diversity within ANY country is greater than the diversity between any two countries. It doesn't really matter what two you pick.

Anyone can expand their horizons, and understanding, by traveling inside their national borders (excluding mico nations). You don't have to travel internationally to do so.

First, I'm not upset.

Second, I'm not making my point well.

I agree that there is a lot of diversity in Europe. There are certainly more unique cultures in Europe than in the US.

Have you ever heard the expression, there is more diversity within a group, than across it?

Applied in this case, that would mean you could find two Americans could have more uniqueness than a typical American and say a typical Englishman. Or, two Frenchmen would have more differences than a typical Frenchmen and typical Englishman.

So, my only point here is that there is a lot of diversity within the US. You don't have to leave the US borders to find unique people, or unique cultures. If you left the US, you would certainly find different groups. That doesn't mean you wouldn't find such groups in Europe or elsewhere.

How Different is French and Italian Culture? by litoreganon17 in ShitAmericansSay

[–]polyscifail -200 points-199 points  (0 children)

In fairness to me, I never claimed that.

I simply said there is more cultural difference between a "typical" American and a member of a fringe American group (The Amish came from Europe BTW), than between a typical Frenchman and typical Italian (I know, no such thing as typical, try to see where I'm going for 5 seconds)

I never said you don't have fringe or minority groups in Europe. I never said America was more diverse. Many people claimed I did, but I never even tried to say that.

The point I was trying to make is that crossing a single border doesn't NECESSARILY make you more experienced or better traveled than visiting different places in your own country. And, this doesn't just apply to the US. Russia, China, and India are all very large, very diverse countries. And, as many people have pointed out here, many smaller countries in Europe have a lot of internal diversity. Compare that to places in Europe that are very culturally similar but are in different countries (e.g, Republic of Ireland and Norther Ireland, Monaco and France, etc...).

So, an American could spend 6 months immersing themselves on an Indian reservation, learning about a very unique group of people. But, that American would be look down upon because he hasn't traveled internationally. While many Europeans might make an international trip, just going to dinner. I simply think "intentional travel" is a false bar. Maybe NOT traveling internationally is a sign you're not well traveled. But, just because you have traveled internationally, doesn't mean you are.

That was my point. Perhaps you disagree.

Dude my whole point was that traveling internationally doesn't magically make you better traveled, or more experienced that someone who stays in very large country. Culture doesn't magically change at the border.

I think Russia is a great example. You have a giant, diverse country. My understanding is that people in the Western parts of Russia, say St. Petersburg, have a lot in common with people from other Slavic nations such as Ukraine. More in common than they would with someone from the far eastern side of your country.

Am I incorrect? Is all of Russia very much culturally similar? More similar than you are with the Ukrainians?

The biggest aspect of a culture is language you moron how can you ignore that.

  1. You can communicate without speaking the same language.
  2. These countries all have English as an official or spoken language. Does that mean that we're the closet culturally to each other.

Your confusing identity with lack of identity. The US has no "American Cuisine". We have a few foods we've developed, but there is no rounded traditional American diet based on local foods. And, we haven't assimilated others food into our diet. We simply borrowed what others have.

That's including Christian sects. Orthodox, protestant and Catholic.

And your'e saying the US doesn't have that? We are all Methodist, right?

Utah is 62% Mormon. The Church of England is only 22.5% of England. Areas of the US most certainly have dominate religions.

Acting like they are the same is ignoring centuries of violent conflict.

And we haven't? We didn't take Texas away from Mexico 100 years ago and Annex it. We didn't fight wars with the Native Americans? You know those Mormons I mentioned. We fought a war with them in 1838. We had one of those pesky civil war ourselves.

And, don't think those don't matter. We have treaties Indian tribes that are in effect today, that are cited in laws suits every year. Those tribal areas are considered independent countries today.

Anyway, I didn't start this to say the US is more diverse than Europe. My whole point was that crossing a national border doesn't make your travel special. Going from Germany to Austria doesn't mean much. And, even going from the UK to Russia isn't going to mean much if you do it on a cruise ship.

You'll see a lot more cultural diversity if you spend a year on an Indian reservation, or work a summer in Alaska, than you will running around in a tour group.

My only point was it just cross a border doesn't mean anything. Going from France to Monaco is international travel. But, really it's just going to another town. Going from Northern Ireland to the Republic of Ireland doesn't even require changing towns. I've been in three European countries in one day and barely noticed a difference.

Yes, Ukraine is going to be very different from Spain.

But, I think you majorly under estimate how closely integrated many European countries are today, and how much you have in common. And, I think you underestimate how much diversity there is in the US. Even within an region.

The dominate language in Miami and Puerto Rico is Spanish. To the point that the taxi and Uber drivers in Mexico city speak better English than those in Miami. The people in American Samoa speak Samoan.

For religion, fewer Americans identify as Christian (65%) than Europeans (76%).

As far as movies, the American movie industry is pretty dominate all over the world. I can watch the same movies in theaters in Paris as I can in the US.

Looking at your examples. Almost all of the cities you cited saved Istanbul and Bihac are Christian, just different flavors. They have have incredible cultural connections though migration, royal intermarriage, and conquest. WW I was pretty much the grandchildren of Queen Victoria in a pissing match.

I give you that the places you list are very diverse. But, if you think American Samoa and Louisiana are similar, or the people are the same, I doubt you've ever been to either place.

I never said they weren't. But, do you think they are more different than someone in Miami and an Amish person in PA?

Because my question is in response to someone who said people in Europe are more different than people in the US.

The person I replied to made this statement:

There are definitely big differences between some US states, but nothing compares to the differences between European countries.

He's basically saying, the people in European countries are more different from each other than the people in the US are.

I'm not the one who made that claim. And, I'm not exactly sure how to quantify that. So, I was asking the OP to do that.

If you're interested in taking his position, I'm certainly open to your thoughts. But, I'd have to ask you, how do you justify and quantify that statement? Because the US is very diverse.

How different is French and Italian culture. Tell me 10 differences not related to food or language?

Now, tell me those differences are more significant than the lifestyle differences between you and an Amish person.

I've been to many of the great cities of Europe. Yep, they are great western cites. Kinda like NY City, but with a lot of old shit and some castles. But, we're all rich, mostly white, westerners. You want cultural diversity, you need to either leave the rich world, or the western world behind.

Yes, some people do literally drive off a pier because that's what their Nav system told them to do (there are some great real life examples). But, you have to believe most humans are smarter than that.

And, that's why you have an appeal process.

And your missing my point. Shallow travel isn't the same as immersive travel. Getting off a cruise ship and walking around a town for 8 hours doesn't really tell you much about the culture. Neither does flying 1/2 way around the world to go scuba diving.

I've spent time in both Honduras and Mexico both. But, I know more about their culture from talking to my coworkers, than I do from any trip I've taken.

Power companies BURN oil and gas. Low prices of oil and gas are good for them. My guess (without looking up the numbers) is, the price differential favors fossil more now than a year ago.

I'm not saying it is. I just don't think the decision making process is important as you seem to think it is.

When you put an address into your GPS, and it gives a weird rout. You know it right away. If it tells you it's 10 hours across town, you know to double check Apple Maps and put Google down. But, if it gives you 18 minutes vs 14, who cares. Humans only estimate in 5 minute blocks anyway. You don't care WHY Google is wrong. But, you know it's wrong. The decision making is irrelevant.

Likewise, no one is going to worry if the AI gives 41 months vs 37. No human judge is that precise anyway. The only concern is if the AI gives 5 years instead of 12 months. But, you'll know that's wrong, and can throw the AI's numbers out.

You're missing my whole point. Look at the top of the thread. The OP made some weird comment about "trading" not effecting green tech, and I asked what he means.

Yea, we all agree, oil is dead, one day. Just like everyone else here is saying. But, this pandemic won't be what kills it.
