Early 90's topical comedy show about a TV newsroom - had some very funny episodes. A little dated in patches now, but most of it still works. I think most of it is up on YouTube.

You should all try this: Remove the printing head from a 3D printer, then completely take it apart, clean it out, install a new nozzle and, the greatest part comes last, put it all back together.
Leveled the bed, loaded the filament, so far, so good.
It's printing now and everything looks ok so far, but let's hold the celebration until it's finished...

I haven't advanced that far yet. I'm still trying to figure out how to prevent warping!
The difficult we do right away...
...the impossible takes slightly longer.

Try printing the object on supports and at a flat angle, like 5 degrees.

Not sure I understand this tip.
How would it print at an angle? The nozzle won't know that the object is at an angle and it will behave as though I'm printing flat.
EDIT:
Oh you mean put the whole machine on an angle?

No. That would not help very much. That's kindof what a mathmatician would seriously contemplate.  Instead of simply turning himself by 90 degrees, he could actually come up with the idea to turn the entire universe (or at least the planet) by 90 degrees in the opposite direction instead. Mathmatically ok, but somewhat impractical.
The plastic contracts while it cools down, so it starts pulling at the layer beneath it. The weaker the lower layers are and the longer the new layer is, the stronger that force will be and the more warping you will have. All you have to do is to rotate the object in a way to reduce these effects.
Let's say you want to print a large cube. If it's big enough and you lay it flat on one side, you may get warping at the corners. First layers to be printed will be very thin squares. Try it and pull it off the bed after only printing the first layer. This thin thing has no strength at all and the only thing that keeps it from warping is the adhesion to the bed. The second layer will contract and may pull the corners of the first layer off the bed, resulting in warping.
Why not print the cube balancing on one corner instead? Of course you now need supports and it will take longer to print, but warping will probably not occur at all. If you look at the horizontal cross sections, you will see that the first layers of the balancing cube are so tiny that warping is not an issue. The cross sections only gradually get bigger and by the time that they get wide enough for warping, there are enough layers underneath that can easily resist the pull from a new layer.

Bed temperature is important, apparently, but bed leveling is more critical. I had warping which "pulled" the prints off the deck if they got too long, scraping them - and fixed it by getting the bed leveling right. The "sheet of paper" method I found clumsy because when you are talking about small fractions of a millimetre it was difficult to work out if the tension was the same across the whole bed. So I used my dial test indicator and a clamp to get actual numbers of how far out of true the bed was, and the paper to get a distance at the "closest point" - the bed centre for me. Took a while to do as each adjustment screw warped the bed and changed other corners, but since I got it done, I haven't had a problem.
Oh, and let the prints cool right down before removing them - definitely below 40C, but <30C is even better. They come off easier and don't distort in removal.
[edit]
And another thing I forgot: clean the bed. Get some Isopropyl Alcohol (Amazon[^] sells it at 99.9% purity in a spray bottle) and a clean lint free cloth. Mine arrived with a very thin layer of yellow gunk I couldn't see which the Isopropyl removed nicely along with the Sellotape / Scotch tape / Durex tape which held the paper to it in shipment. Removing that helped with adhesion as well!

...that MS is going to have a whole load of work on their hands soon.
All of it's documentation only works properly with Edge, it's useless with the Chrome renderer (probably to make you use Edge).
Open this in both: Image.FromFile Method (System.Drawing) | Microsoft Docs[^] and see the difference.
And the new version of Edge will be Chromium based ...  UBlock can get a bit ahead of itself ...

works perfectly fine (and identically) in both chrome and palemoon (firefox) on linux.
perhaps problem is only with w10? so shouldn't affect many serious developers.

The CSS is failing to load in Chrome for some reason. What do the dev tools say about that?
What do you get when you cross a joke with a rhetorical question?
The metaphorical solid rear-end expulsions have impacted the metaphorical motorized bladed rotating air movement mechanism.
Do questions with multiple question marks annoy you???

"ERR_BLOCKED_BY_CLIENT" - turns out it's uBlock disabling CSS for no obvious reason (which explains why it's the same on all my Win10 devices).

Uhhh... dude, it works fine on Win10, in Chrome 77, Edge, and IE 11. Identical in all browsers.

Interesting - it's been like that for ages, so I just assumed that it was MS trying to push me to Edge a little more "aggressively" than usual.

Looks the same to me, although Edge shows me C++ code instead of C#.

Step 16 of about 60. Taking apart a device with that kind of instructions really is a pleasure. 
At least the PDF has lots of pictures. For idiots they obviously intended it to work as a comic book.
