I live in Copenhagen, Denmark. There's half a dozen scuba clubs in the area, and I'm a member of one of them. I got my speedboat license and the club trained me to take one of the boats out. I'm hoping to get the training for the second (larger) boat this year.

This means anytime I feel like going diving, and the weather is forgiving, I have a whole boat of people who want to tag along. I have a core group of people I dive a lot with, but basically anyone in the dive club is a very decent diver. Most of them have hundreds of dives, some of them in the thousands, and some of them at levels I can't even begin to completely fathom. Very hardcore technical stuff, sidemount CCR in Norwegian caves and stuff.

Dive clubs cost money because they're expensive to run. I pay about 15€/$20 per month. With that, we get a full trimix filling station with either partial pressure or continuous blending (doing my tech blender course this afternoon), a fully stocked workshop, 2 boats + trailers, a trailer for gear when we're going on longer trips, 4-10 trips per year abroad (not included in the club fee, obviously), washing and drying room, storage for gear, cylinders, etc. Air fills are free and unlimited, nitrox/helitrox/trimix obviously we have to pay for the gases we use, but the club sells oxygen and helium at-cost. We also have a bar with at-cost drinks.

We have old-timers in the club who have been diving for 40-50 years. Some of them still dive to this day. They are a wealth of information.

If you have the gear and want to dive multiple times a week, year-round, then joining a club is definitely worth it.

Not sure what you need to get approved. Buying a roll of ASA? It's part of printer maintenance, and making it more reliable in the long run.

And if you don't have ABS/ASA on hand... why is the printer in an enclosure?

It's the PETG. Specifically, it is the softening on the following parts:

  • y-belt-holder-R2
  • y-belt-holder-tensioner-R2
  • x-end-motor-R2
  • x-end-idler-R2

I would recommend the following Y-axis mod for the MK4. I am still running this even on the MK4S, even though the Y-axis was modified on the MK4S.

Edit: Print those in ASA and replace them, tighten all the belts as usual, and I think your printer will be fixed.

My money is on the PETG starting to loosen and you losing tension on the belts.

You have the MK4 in an enclosure--I did too. At some point I stopped being able to print flexibles, but ASA/PCCF was still fine. Prusa support told me that the idler was getting loose and my hotend was losing grip on the fillament.

I had another print where there was a nearly 2-3cm shift in the layers between layer 5 and layer 80. Some of my belts had absolutely lost the plot. I reprinted everything in ASA or PCCF, and while upgrading to the MK4S rebuilt the printer with all ASA/PCCF parts. No problems since.

Non mais, c'est quoi ce langage alarmiste?

C'est quoi le but exactement? De faire croire aux gens que les airbags sont plus dangereux que... checks notes... s'exploser le crâne sur le volant, en cas d'impact?

I'm someone who builds cloud infrastructure for a living. I only touch AWS (Amazon), but the same applies to Azure (Microsoft) and GCP (Google).

Kagi is private. Saying that they "rely" on Google because they use GCP is akin to saying that the US Army relies on General Motors because they use Hummers. It's just a provider. They're renting virtual machines, compute power, storage, and network bandwidth nothing more. You can use GCP/Azure/AWS without your data ever being visible by GCP/Azure/AWS. It's not because you use GCP that you have to use AdSense/Analytics/Fonts, etc. They are completely separate.

Politicians would have a field day with all the cloud providers if using one thing forced you to use everything.

It could be a case of too much cooling, while simultaneously being too much heat.

If you’re blowing so much air that the filament instantly solidifies when it leaves the nozzle, it’s not going to bond with anything else. It’s also interesting that the first layers are fine (when the part cooling fan is typically not running), but problems start when the part cooling fan turns on.

Have you tried without part cooling at all? Another thing is that your part cooling might be cooling down the tip of the nozzle, causing tiny partial clogs, which are cleared every so often by friction.

Did you notice a difference in print speed when you slowed down? As this is a small print, it could already be as slow as it will be due to minimum layer times.

It could also be that the nozzle spends too much close to the print. What happens if you print 2 or 3 of them?

This is typically more of an issue with PC where you don’t have a part cooling fan running, but maybe it’s the case here too?

Definitely doesn't sound like an issue with Tor Browser in Strict Mode. /s

The simple fact that buying a $300 device and to "not expect software updates" is not considered a scam is hilarious to me.

If the point is to monitor the other divers' cylinder pressure, I believe there's only the Garmin transmitters that have sufficient range for that (and even then, it's tricky). Most transmitters will top out around 1-2m range, whereas the Garmin transmitters can have a range up to 10m (in ideal, line-of-sight conditions). I believe you can have up to 4-5 transmitters paired with a computer.

I would recommend teaching everyone good habits and have them monitoring their own pressure, but that's just me.

Interesting that the extra 10° makes such a difference for ASA and ABS.

I recently started printing with ASA in my enclosed MK4. I might have to try this.
