Red loctite on fastners that small has a recipe for being a bad time if it sets up proprly, I find some of the small screws around the hotend can already be prone to stripping due to things like plastic buildup thats hard to remove.
At least on the dragon, theres a sizeable gap between the inner and outer portions of the heatbreak and some distance between the block and the heatbreak, I'd be surprised if the threads get hot enough to worry about even without the hotend fan.
It's amazing how much our views change with time. My dad was definitely a super early adopter of cable when it became available in our area, if I recall it was 16 Mbps which was unreal to me in 2002. I made do with 5 Mbps in uni and it was totally usable.
But now, I've had 1Gbps for years and wow it's so different, changes your habits too. I don't hoard installed games as much, I can pull them down in minutes so why keep something installed if I'm not going to use it?
I swapped over to phaetus dragon hotends on both my printers for interoperability and the fact that it doesn't rotate on me, making nozzle swaps less of a pain. Was running this mount on my mk3s, works really well, no complaints from me. Also used this fan duct with solid results.
Personally I lean on real-world designs, honestly I haven't taken advantage of some of the things that additive manufacturing enables over traditional machining so pretty much anything I've done could be done on a mill + lathe as well. Do lean on reference material though, dusted off my machinery's handbook for some gearing references recently and I don't doubt that I'll get use from some of my other textbooks from uni, dated as they are.
I went through prusa's documentation on designing for 3d printing when I was getting setup again as it had been some time, that covered things like overhangs, horizontally oriented holes etc. With all that said, I've always been an iterative design person, sometimes that's also iterating on existing work, really appreciate the open source mindset in the community for that.
In an alternate timeline I totally should have bought bitcoin when it was memed on and was literally sub pennies. On the other hand, anyone I know with wallets that old either have lost access to them or spent them when they went to a few dollars so likely wouldn't be any different
I did a board swap on my mk3s with one of those, other than doing a few connector changes perfect replacement and they're really reasonably priced. Steppers run way quiter as well which is another benefit
It's really just a good example of how much energy phase changes take, all you're really doing is expending work to make your refrigerant condense and evaporate where you want it to.
Heatpipes also exploit phase changes, just passively, it's why they move so much energy.
My MiL has this ancient deeply yellowed office grade HP laser printer she dug out as her document printer, it's a tank and runs like a dream. Found that driver wise it seems to be easier to setup in Linux than windows, I keep meaning to setup a print server for her with an old pi I have..
That may actually be one of the weirdest issues I've ever heard of, were you ever able to figure out why it would only give you 2.5 pages?
Wow that sucks even more, I had thought there would be a bunch of crash protections built into their firmware, prusa usually has pretty decent support so sorry you're dealing with that.
I bought an old simple HP LaserJet like 4 years ago, it's probably the worst printer I've ever used and that includes the crappy bubblejet printer we had as a kid. Shit you not, I pretty much need to hand feed the thing, it almost always fails to grab a sheet out of the tray and it's usually crooked when it does.
Wish I hadn't given my brother printer to my parents when I graduated honestly, was solid af. It'd be 16 years old now but still going strong.
Oof that's rough. I have marks on mine from bad 1st layer offset from the first time or so I used the sheet on my mk3s, but they're more just lightly shiny rather than gouges. Definitely show up on the print but it's fine otherwise, and honestly the spots aren't the worst.
What happened when that was going on? My experience with the voron tap a dirty nozzle would make the 1st layer offset too large and move away from the bed, not crash it.
The entire field of reliability-centered maintenance comes right out of aircraft maintenance in the 60s and 70s, term itself was penned by people working for united. It's responsible for massive improvements in aircraft reliability, there's a reason that you can point out specific events like this in the modern era.
On a different note, a lot of the guys I worked with out of uni were all aircraft mechanics who had served in the air force.
There's a Firefox plugin that provides that functionality. As for getting my parents on board, any attempt to get my mil onboard with a password manager has been futile, actually using it seems to be the biggest barrier to adoption in my anecdotal experience
Did not know about the Mac version, my partner is using Strongbox on her mac, I don't personally use Mac os. I've been using keepass2android for a long time, I like that there's so many different clients for keepass
