There's an interesting contrast between engineers and self-taught folks (like myself), engineers tend to understand the process more, and are therefore better equipped to plan ahead. As in, make a plan, find the parts, explore other options, improve on the plan, then execute it. The old "measure twice, cut once". I honestly caused myself major issues when designing a 3D printer because of my misunderstanding of the process. I made a plan, found the parts for it, ordered them...than figured out hot to improve on the design, but stuck with the parts I had, found better parts, shifted my design again, noticed that some of my parts don't exactly work well together, had to change the design to accommodate... It was a mess.
It's good to see videos like this one, not just tutorials on how to do things, but to actually hear people with experience talk. Tutorials make us feel like we can just do things, and sometimes we can...but that doesn't always mean we should. Hearing people with experience talk is a good way to realize just what exactly you want to build. Like your water cooling question here, it sounds cool, but usually there are better options. It can be done...but all alternatives should be considered first.
I've done repairs to enough regular printers that put text and images on paper to know that some supposed engineers probably slap things together without much planning. Some things just seem like an afterthought based on the way they're placed, like a switch that gets pushed by a long thin piece of plastic that breaks very easily.
Yep, most “engineers” don’t spend enough time to get things right. I spent a day redesigning a part because I realized some of the bolts would be difficult (not impossible) to get to.
The time to fix issues like this is when everything is still in CAD.
Every time you make a decision, imagine you’re personally making 10 of them. So I’d spend 10 design hrs to avoid spending an extra 1 hour in assembly. Because on a prototype, you’ll probably end up taking it apart and putting it together several times, and on production machines you’re wasting money with each unit built. So it’s almost always wise to focus on assembly - it’s even more important than performance.
at the end of the day, as an engineer myself, it is mostly about risk management. identify the risks, evaluate them, and then take necessary action. what you've done actually mostly surmised the process. The difference is that engineers have a specific method to assess the progress at each level. but then again, how far ahead can we plan? most of the time, much of the processes have been rushed because of project "costs" and "timelines" rather than focusing on quality (CTQ triangle).
Bowden came about as a direct fix to the inadequacies of direct drive, at the time the heavy motors used for direct drive would cause artifacts on the print, I still have a couple of Bowden machines and I still use them quite regularly.
Yeah, if they work, they work!
Finally, Nathan Builds Robots. Up until now, Nathan Begged for Relevance. Or sometimes, when Bambuu Labs wouldn't send them to him, Nathan Bought Robots. Glad to see this new direction.
Lot's of learning for 30 min, thanks
Dude knows his stuff, your questions really demonstrated your expertise too!
I just am good at pretending :)
Great episode. I love the technical design stuff. Thanks to both Nathan and Luke.
very good video
First time I hear someone talk about WHY using different types of scrows.
im going to google more about it now
Great info and dialogue NBR. I enjoyed it.
Really enjoy these interview/podcasty style videos
yeah i think these are some of his best works
the cast tooling plates sounds promising. as soon as i saw there was a quote process for his printers i knew i couldn't afford one lol
It's not that bad. I bought a 1/4" Cast Aluminum Tool & Jig Plate (ALI14) ~590mm x ~590mm (23.25" x 23.25") w/Cert for $99 + $17 shipping from Midwest Steel & Aluminum in 2021. The current price for the same X&Y dimensions is $141 for 1/4", or $176 for 1/2".
Please note that I have no association with Midwest whatsoever.
The quote process is mostly to make sure people get the machine they need, whether it be size, temp, or other features like idex
Good Chat! Love listening to a couple of well respected 3d print gurus. Does this colab foreshadow a possible NBR spec printer down the line?! Gosh I hope so!
Maybe...
Honestly really good video, I need a part 2.
I think every printer should be built in titanium and fishing line, powered by a steam engine.
Haha. Love how vid ends in the middle of his merch pitch. Great conversation! So much respect for Luke. He can call it stubborn, but the man is doing the right work. How to trust your tools, materials and collaborators. Curious what he builds when he's not solving other's problems
Loved this one. But you shouldnt have said " you loosing us" when he talked about stress relief of the alu plate😂. Love technical details. Thanks for a lovely video
Excellent video idea, thank you very much!
fck me the dual channel audio is trippy and top notch. Love it
Putting you in the middle of the conversation 🤓
First. Lukes the man.
I sure hope you end up covering the Magneto X.
You know something I've been wondering. Can IR LEDs be used to heat a surface? I think an LED heat bed might work really well...
I don't have a magneto X. It seems a little over complicated with a heavy and inefficient motion system, which means it probably won't have the best quality at super high speeds.
But if they are using linear encoders it should allow a higher level of precision than anything else.
Is any of that necessary? For most people, no.
I've spent a lot of time thinking about using radiative heating for 3D printing. The problem is metal doesn't absorb heat as well as plastic, and it changes per material and color.
You could use it to heat a bed and possibly get rid of some moving wiring, on a bedslinger for example. But its a lot of cost and complexity when the alternative is $1 of heater wire.
@@NathanBuildsRobots Well I was thinking about it a bit differently. I use glass on my bed and print a fair amount of asa. I also try to run my chamber temps up into the 60C range. What I was thinking is a hot swappable glass bed. The glass has a black coating on it that the IR LEDs heat up.
I do hope an opportunity presents itself that you get to play with a magneto X. I'd really love to see your hands on thoughts.
The audio split is a bit weird using headphones. Would have taken an even longer video. I need podcasty content while I work on my new printer.
Yeah I was going to say this as well
@Nathan your hate for none socket head screws is misdirected tbh. Most of the time you're stripping BHCS for example, it's because you are using stainless steel which is know to be soft. Try alloy steel bolts instead!
Grade 12 bolts all day!!
He other issue is my stockpile of kit Allen wrenches that are included in the cereal box (with cheap printers)
Great, but what about screens? There are so many connection protocols and search and search I have never been able to find a site that explained them. IE: how many wires from control board to screen? What is a spi screen? What is a dsi screen. Does this xxx screen work with this yyy control board?
is there a component reliability data that I can at least go through? coming from maintenance and some reliability background would love to at least be able to determine exactly what parts are the most important to have critical spares and what nots. of course reliability for the printer poops going off the chute compared to being flinged across the print bed is important too 🤣
"Linear rods shouldn't support weight."
Ender5/SV05 owners can join me in the crying corner
Could have listened for another two to three hours
The other guy looks like William Osman had a baby with chuck Norris
That’s not how babies work…
i've heard roller screws are even better than ball screws
Those look amazing, something that might be fun to 3D Print!
I have never heard of them or seen them in practice though, where do they find usage?
@@NathanBuildsRobots i think is was high load (because they give greater contact area) and absolutely no backlash.
no idea which sort of machine depends on them to be able to function, though.
