Here’s what that looks like for me. Basically a controller_fan configured to kick off with the steppers.

#Case fan for cooling when heating bed [controller_fan controller_fan] pin: YOUR_FAN_PIN_HERE heater: heater_bed stepper: stepper_x,stepper_y,stepper_z heater_temp: 40.0 fan_speed: 0.8 shutdown_speed: 1.0 kick_start_time: 0.5

Is it running Klipper or something else?

In Klipper I have my controller board fan set to speed up only when there’s any active heaters or stepper drivers?

E.g. fires up only when moving/heating or printing but not when idle. Even then it’s set to a reasonable 80% threshold.

I feel you on getting these things settled. My Frankender is pretty reliable and making sure the foundational stuff is good is key.

Here’s a comment I made here about a year back breaking down how to square, align and level these things

The context is Klipper which I’m running but the physical stuff applies across the board

May be a good time to see if there bits of filament in the extruder gears and if they’re ok. And, if they are, to clean the nozzle either by using filament or a cold pull.

And there’s the issue with embedded security stuff.

Because they’re really good out of the box printers and prior to this for somebody that wanted something that “just works” it would be Prusa or Bambu I’d recommend.

I love tinkering and tweaking and I’m building a Voron but it’s not hard to understand how overwhelming choices can be and it’s understandable that people would choose to lock into an ecosystem specifically because it lets them just print.

I would never buy a Bambu and wouldn’t recommend it for anybody building a company with essential components having them in the pipeline but then again most people aren’t that aware and their research, understandably, led them to buying one.

I agree with OP, this is an opportunity to be empathic and to help them. And they’re learning the hard way a lesson they’ll take forward. I’d prefer that lesson to be “more careful” and not “these people are snobs”

If there’s no periods of rest… yes.

There’s also the retraction/wipe of filament. So if you can’t do it inside the print then the tower is used to give that surface to wipe off against.

Worst case then would be boogers/wisps

The blood vessels can be permanently damaged from an erection that long so it tracks.

This is why the Viagra commercials have that “if you have an erection lasting longer than 4 hours” bit. It is a serious issue that if not addressed can lead to permanent damage that can make it impossible to have an erection.

The panning effect reminds me of the chopper in Metallica’s One (definitely want headphones to “feel” the effect)

This isn’t my particular skill/talent but I found some info that I hope can help. But do take it with a huge grain of salt and definitely look into what others say with the relevant experience.

They can be. Anathem was a bit more of a slog that sped up.

I found cryptonomicon to be slow at first (but not like Anathem) but it sped up quickly.

It goes back and forth between “modern” early 00’s? And WW2.

Stephenson is the kind of author you start a book and after a bit you’re like… ok… I don’t think this is for me… wait… what? And then you’re hooked.

Anathem is one of the worst that was like that. Snow Crash would be the polar opposite and one of the rare ones that just jumps straight into the world building.

Unrelated: I just finished Wind and Truth. So weird to think somebody got me hooked on Sanderson about 2 years ago and I’ve burned through all his books (except for Reckoners and the Alcatraz books). The first because I haven’t tried one but seems a bit more youth oriented and the latter because it is more youth oriented than my usual tastes.

You will. The Great Silence was very poignant. But yeah, there’s a great variety of stories.

I’m just starting The Apt series (guess I’m doing Tchaikovsky in reverse) end will finally get to the children of time series when I can get it via my library or I might just bite the bullet and buy the audiobook.

Air sick low lander. How could you miss Tchaikovsky…

But seriously, he’s a great author. And Chiang is great too. I don’t think I’ve read any of his short stories and come away disappointed. I mean one of them became the basis for the movie Arrival.

They don’t always end on a happy note (most are hopeful) but they’re true to the story they tell.

Just hit me. More modern time… historical fiction at the start and blends into more sci-fi as the series goes on.

Neil Stephenson: Crypto series

Cryptonomicon Reamde Fall: or dodge in hell

Different perspectives from not alien but not human (unless otherwise specified not hard sci-fi)

• Klara and the Sun (story of an android coming to awareness of themselves, to their purpose as a friend for a child, to attachment and love as well as dealing with the inevitable changes and loss as the child grows up)
• Several short stories by Ted Chiang
  Exhalation, The Lifecycle of Software Objects (technically hard sci-fi), The Great Silence

Kind of human

• Murderbot Diaries (Autonomous killing machine/human cyborg going rogue that is learning what it is to be human, and just wants to watch serials and be left alone)
• Ancillary Justice (Ships with remote/linked instances in control of human bodies and what happens when one of those “remotes” is all that’s left of that consciousness. Navigating the line of human/machine/etc.). Not political per-se but resonates with various political perspectives on autonomy/society vs individualism/ etc.
• Dogs of War. Bio weapons part animal human hybrids and wars, morality, doing what your meant to do and made to do vs becoming aware of your actions and what is right/wrong.

Yeah. Three body problem is a well done translation of a Chinese authors work and so I suspect there’s some things that just culturally come across easily. Nothing makes that more obvious than the sequels where it feels like it wasn’t as painstakingly done to try to convey such things like the first.

I will say I really enjoyed the paper ménagerie by Ken Liu (the aforementioned translator) and it was a unique look from a different cultural perspective.

Back on topic to sci-fi. Do you prefer singular protagonist in a limited scale of time (person/crew) fighting against some local challenge (Martian/Expanse) or larger sweeping epics spanning centuries and a lot of perspectives (Dune, Foundation)?

More human/realistic perspectives (Martian) or are you open to Alien/Non-human perspectives (ex. protomolecule perception about the gates reopening)

I checked the good reads list of top rated hard science and saw a few items I can recommend.

• Altered Carbon. A fun and intense read. Future hard science. If people’s consciousness could be transmitted/used for interstellar travel kind of thing then the scenarios listed here adhere to their own crazy rules.
• Three Body Problem. First book is amazing. The sequels are good enough but the translations are a little rougher but the story carries through.
• Enders Game. Tactical and hard science aspects to it. Gets more metaphysical later in the series.
• Contact. Absolute gem that I re-read a few years back.
• Ancillary Justice. More future/hard science but worth mentioning in any list I’m willing to put Altered Carbon in. It has a viewpoint and it’s use of alternate societal perspectives (from a society that is uniform in so many ways to organic “ship” drones to questions about what is a person/identity) all wrapped in a great sci-fi story
• The moon is a harsh mistress. A little dated and the way women/people are referenced shows it (much like foundation) but a solid one that is a little more hard science and may be more in line with what you’re thinking of.

Going over this list I realize how hard it is to find true hard science (Martian) that doesn’t lean into the more future tech but consistent physical laws (Expanse) to way future nano tech or consciousness transfer (Altered Carbon, etc)

Do you like protagonists that use their wits to beat a scenario or the hard science more?

For example a fun read that’s, in my opinion, best experienced as an audiobook is the dungeon crawler carl. It’s definitely a good example of the first type. It’s not realistic. It’s literally real life made into a D&D game (LitRPG) it is just one scenario after another of Carl just finding ways to manipulate and play with the “rules” of the messed up game.

If you’re more into the hard science than The Expanse as others have said. Or maybe even the Revelation Space series where it is future tech but relativistic time plays a part. Less of the “one person/group against all odds” but a good read nonetheless.

Oh that sounds like fun.
