do you have any advice for someone like me who is still in college studying a trade or career path? For example I would like to build my own inverted extrusion 3d printer which someone has made on their own similar to this guys start from scratch but doing that can be a bit daunting as I am not aware of possible blocks such as coding.

The technology isn't "available right at the starting line". Far from it. The arc controller alone is nearly $3000 Euros (!). That alone puts it out of the reach of most "hobby" guys, especially a someone on a beginner budget. What is available today "at the starting line" (i.e. as a complete novice machinist) is the internet and youtube, and the ability for people to share ideas like this. Before you'd have to apprentice at a shop for years to even operate such a machine. I would hardly consider this EDM machine a "beginner" level machine to build as quite a few other processes and skills (CAD, Fusion 360, 3-D printing, proficiency with various machining operations (lathe/mill), etc) are necessary to construct such a machine, and there's a learning curve on each of the afformentioned skills. You'll also need to be extremely ambitious and have boatloads of free time, money, and the right equipment to put it all together (or you'll need money to pay someone else who does. Many people may not have a month or two available to drop everything they're doing and build one of these when they have bills to pay and customers to serve. STILL, it is great that BAX has made plans available for those who are skilled and ambitious enough to tackle such an undertaking!

I'm getting to the stage of old timer and I feel the same way. There are different types of old timers. The ones who want the new guys to go through the same crap we did, and then there are the people who see the future through the eyes of the new guys. Why wouldn't we want to make things better for them. We should be excited that they don't have to put up with the same nonsense we did. Anyhow, better get back to the flint knapping.

​@@komoru You missed his point by a mile. He said available, not affordable. And I don't want to put words in his mouth, but pretty sure he meant some of these new technologies didn't exist, wasn't feasible, or maybe only existed in a theoretical level. The first 3D printing pattern was filed in the mid 80's and it only became a mainstream and affordable technology in the last decade or so. And that's just one of many new technologies that is now available to anyone. It's not like anyone could afford a full sized milling machine and lathe right off of the machinist school either back in the day... Anyway, the point is, if you want to be an inventor prodigy, go right ahead. Yo have a lot more and lot better technology available than the old timers did. You can't afford it? That's a You problem.

What is not widely known is that the technology available to "makers"(a ridiculous term that pseudointellectuals came up with to make them feel special) today is actually outdated, recycled tech made in China. If you are just starting out in manufacturing, you really need to learn from highly skilled people in a modern manufacturing environment. For example, That "servo" motor he used to drive that spindle is actually an encoded stepper motor, not a servo motor. My point is that if you want to be a manufacturing professional, don't cut your teeth on 30 year old technology.

I was looking for this comment, I agree

@@kingcosworth2643 same

Same

I knew I was not the only one to wonder about this. Lol

Optical illusion M6 key is 4mm

Exactly, being magnetic doesn't necessarily mean it's not stainless

Yeah, but since it took blueing so well it's most probably not stainless anyway

@@avelkm agreed

@@avelkm good point from u, i hear stainless does not take blue, however cold blueing AFAIK does not provide any corrosion resistance!

Yes to above comments. 17-4 stainless is magnetic, its about as corrosion resistant as 304, and is very strong, high yield strength, good elongation before failure, and widely used when you want a high strength steel with stainless corrosion properties.

Hubble is.having this problem i think. They are down two reaction wheels and using the remaining ones with some voodoo generated software code to compensate....

isn't it funny how smart you can be, think of every outcome and then BAM! The ol' static bearing discharge problem again. :)

Usually correlated with strong solar activity. The funniest part is the solution came years before they figured out why they failed. The bearings were switched to ceramics quite a few years before the static discharge failure was explained.

Fun fact show me a picture of a satelite. Spoiler alert you cant

Scott Manley video on this: kzfaq.info/get/bejne/gc-Sh5CBqrOshYk.html (interesting comments too) But "lots of old satellites from early space exploration" makes it sound like this happened several decades ago, when it was much more recent than that. Kepler, Dawn, Hayabusa, and other relatively recent spacecraft are suspected to have had reaction wheels fail due to this.

Any shape! Non symmetrical even.

Stainless set of collets next? 🤔🙄😁🤣🤣

If you build it, we can hang out more. :)

Thanks for sharing! More rare tools in the works 😁

@@baxedm9806 Nice; I'll keep an eye out for them. Let me know if you want a free premium forum membership so you can post your videos on the forum whenever you want. We have lots of YTers on board.

Depends on what you're doing. Small stuff like this, sure, but if you need fast cuts plasma or laser are the way to go. Waterjet I don't think is great for home use though. The benefits of it just aren't there for the home DIYer.

EDM is stupendous precise, but also quite slow

I often wonder how these you tubers afford to do all the very expensive projects. Are they born wealthy? Are they balls deep in debt? Being poor sucks.
