A nice thought. But the Great Unwashed Masses do not care. They want a Quick Start Guide that just says "Plug it in" and no other steps required. They want the black box because they don't want to learn and understand.
And that attitude is less about the oligarchy and a lot more about all lazy people.
They all lobby the regulatory agencies for the same things. Tesla ain't special there. Every auto manufacturer has formulas that they use to determine how many deaths cost them more than doing nothing does.
In the western world, deaths from bananas to cyber trucks to rocket ships are tracked. And believe it or not for many of those things there is a threshold of deaths per month or year that is required before any safety concerns are invoked.
They have charts with actual numbers to decide on how many people need to get hurt before a stop sign at a street intersection gets installed. And how many deaths need to occur before those stop signs are upgraded to stop lights.
While I don't own a cyber truck or anything Tesla and never will. 5 deaths out of however many miles driven by the over 1/2 million cyber trucks that have been sold, is barely statistical noise.
*****Annual deaths from bananas is statistically insignificant. But strangely PubMed did have a German paper about a woman that evidently committed suicide by eating a very large number of bananas. Hyperkalemia is a real thing and there are people at high risk of it. But man, kidney failure is a very painful way to choose to die.
I spent all my childhood life growing up on a dairy farm. Worked from home, got to do various types of exciting manual labor and operate somewhat dangerous machinery, AND I got to work outside no matter the weather.
So suck on that California. You ain't that special.
Even rifling can be cut with nothing more than a hardened piece of tool steel, a green sapling and a bit of time and patience to make what's called 'Scratch rifling'. Even a wooden rifling machine isn't hard to make if you want to boost production a bit.
And yes, the metal working shop I own is perfectly capable of making every piece of any firearm you might want. I have even made a black powder 2" Coehorn mortar to launch baby food jars filled with concrete 100s of yards. I know guys who have made full sized and functioning Gatling guns down to the horse-drawn trail it was mounted to. An expensive and time-consuming endeavor.
But it makes the general populace feel good and gives politicians more power.
Immediately, there should be little issues. The woodworking dust being the worst, it's insidious.
Long term, you will shorten the life of your printer some as all the components go from cold to hot. Will it be horribly noticeable? Possibly. I need to keep my machine shop at least at 50F/10C to keep the electronics functional and rust at bay over the long term.
Firstly, never take legal advice from youtube or even here. And it's very unlikely you would ever be caught doing it as long as you don't sell the parts. Nor should you ever reverse engineer life threat level parts. Because you ain't that smart or good. And if you are that smart, you know better than to do so.
If you are reverse engineering something like those used sleds, it's unlikely you are going to have any kind of paper to give you those critical dimensions. As he said, those sleds were bought second hand. You ain't ever going to get any kind of manual with them.
As far as measuring goes, It's all G20/G21. I'm pretty sure the overwhelming vast majority of 3D printing people own a 6"/150mm digital caliper. Metric or US Customary numbers are available at a mere push of a button. And you should also own a 6"/150mm stainless steel scale. Evem Mitutoyo are less than $20. Though I prefer Shinwa brand myself because I find them easier to read with my old feeble eyes. Buy one or several. But to be honest, just about everything in the US these days is metric. We just don't brag about it.
Those are the 2 basic tools you need at your desk when you are reverse engineering a part or design something the new the world has never seen. Add a pencil and a sketch pad and you are set.
I know it's not as popular anymore, but this is why we calibrate our printers. [(https://ellis3dp.com/Print-Tuning-Guide/articles/index_tuning.html)] This is an excellent guide to getting your printer to work to near perfection if you do all the tests. But it does take time and effort to learn and do.
If you switch to Orca, they have a pretty decent calibration suite built in. It's not as rigorous as Ellis, but good enough for most things.
You can go on you tube and search for "mini excavators" or "mini skid steers" if you want to see machinery lawn ornaments. Now, there are plenty of people that own mini excavators that really use them for making a living. But theirs either say Kubota or Bobcat on the side and cost a LOT more than the $2500 these guys paid for the one they just drive around their little suburban acreage.
Yes, yes we do. I own a 24,000lbs tandem trailer that I haul large stuff heavy stuff with at times. Sometimes 300 miles one way. I have a good reason to own a pickup truck that says Hemi on the side......
Those swave and deboner urbane urbanites seldom have an actual use for a pickup truck. But there are places where the trucks wear the scratches and dents of their hard use proudly.
I don't think those fans are bad, just noisy. And noisy fans are a thing for a lot of less expensive brands. They tend to use sleeve bearings rather than more costly ball bearings and the fan designs can be not optimized for quiet operation.
I would keep using the printer and monitor the sounds of the fans. If it gets louder or odd new noises appear then something needs to be done. I would recommend starting to look for fan mods for this printer. I'm sure there are some out there. Ender printers have a very active user base for modifications and help.
