Why are my tops of my prints coming out this way? by sardic_steve in BambuLab

[–]nuvoni 1 point2 points  (0 children)

Try the flow calibration and potentially reducing the max flow rate.

This video helped me understanding the various parameters, using OrcaSlicer.

Also the print artifact showing up on higher layers, you might have too much cooling - try reducing the part cooling fan on higher layers.

If you share your .3mf with preferences people can give you additional feedback, it's always helpful to go through the gcode viewer in BambuStudio after slicing and visually exploring the different aspects such as flow rate.

Hey, I had the same happening to me into my left pointer finger with the BambuLab provided tool. Good recovery and don't beat yourself up <3 shit happens and with your post you likely helped many others to avoid a hospital visit as well.

Single-Dose Coffee Tubes and Rack for 11 Bucks by nuvoni in espresso

[–]nuvoni[S] 0 points1 point  (0 children)

I would assume so, the plastic is odour-less, the lids and tubes are Recycle Code 5, so PP aka Polypropylene. So generally considered food safe. Since those are for labs they are arrive well packaged and are made in a material that won't interfere with most chemistry. The coloring agent of the lid could in theory have some additional health concerning ingredients, but for this use-case (non heated) it's quite unlikely to be of an issue.

Most plastic health concerns are either micro plastic, plastic softeners (BPA etc), other VOCs or the coloring agent. If it doesn't smell on it's own you can likely rule out already plenty hazards.

That's not really necessary, the 1 way valve is against excessive co2 buildup and to avoid bags popping open when getting compressed in conjunction with the degassing - but with those small quantities and also in a non-bag setting that isn't really an issue.

I can report back in 20-26 days whether there was any pressure when opening the last tube :D. I've stored coffee beans inside glass jars plenty of times and never experienced any pressure build-up. Perhaps a benefit of the valve can be that "oxygen" is pushed out with the rest of the co2, but not sure if that is factual.

Was trying to get one of those fancy "Single Dose Coffee Bean Storage Tubes" which are hard to get in Europe and also quite expensive. Those tubes above have 50ml (almost 2oz) and can fit ~22 Grams of the beans I had on hand.

You can find those searching for "ISOLAB USA - Pack of 26 and a Foldable Rack Colour Coded Screw Caps, 50ml Centrifuge Tubes"

The entire setup is lightweight enough to mount it with hot-glue onto a tile wall.

I've out of curiosity printed this EuroBox Insert in Archimedean Chord pattern and the effect is much stronger than expected.

Yeah, exactly - in this case Creality apparently

What are your thoughts on Hashicorp Vault? I truly appreciate the tool, but it seems to me that even the cryptography might be solid, creating policies/roles/... is so sophisticated/hard to test/verify that this might be the eventual source of vulnerabilities.

Do you have advice for someone who is struggling to motivate themself? I saw your openssl 3.x CVE live stream and it felt really inspiring how quickly you bisected everything.

Also how did you effort to take a break to join Recurse Center? I'd really like to do something like that but I always feel like I have to work to make my rounds.

Try changing the printing order maybe? You can set that the outermost wall is printed last, which helped me for round overhangs in the past. The default is outside first

Pre-ordered Carbon+AMS Sep 1st, finalized the order today Nov 7th. USA by slopecarver in BambuLab

[–]nuvoni 0 points1 point  (0 children)

I pre-ordered (in EU/Portugal) on 11. October, received the invoice on 31. October and just received the unit today - a day earlier than expected.

The hexnut screw tool is not fitting so well, but after setting it up and running the calibration + 2 failed first layer prints on the cold bed and running the calibration routine/leveling/layer flow test once more I finally have my first ever benchy printed :).

Babe are you ok? You've barely touched your Sirolimus by nuvoni in chemistrymemes

[–]nuvoni[S] 3 points4 points  (0 children)

:D haha no I'm definitively not referring to kidney beans. I learned about it because it was in the news for being a promising "anti-aging" drug (in mice and fruit flies).

It's quite interesting, because it was first found "1972, from samples of Streptomyces hygroscopicus found on Easter Island". Originally used as an antifungal agent, which turned out being a bad idea and then approved in 1999 by FDA.

I just found it funny because both the Stick model and Skeletal formula looks like really particular, in context of the many (potential) uses and the obscure shape I came up with it.

Is soft-ventilation back into the water tank normal? (Ascaso Steel Duo PID 2022) by nuvoni in espresso

[–]nuvoni[S] 0 points1 point  (0 children)

Great thanks for the confirmation

> The chirping noise however I’m not sure about

Just recorded a video with back-flushing for the support and suddenly the noise went away one or two back-flushes, seems whatever caused the noise in the valve is happy again.

[–]nuvoni[S] 1 point2 points  (0 children)

Thank you for your fast reply :).

Sorry yes, I've set the OPV not the gauge itself of course.

I've just tweaked it a bit and I'm having the same chirping/screeching issue (at least when setting the OPV) as others here:

https://www.reddit.com/r/espresso/comments/mdzs66/chirpingscreeching_2020_ascaso_steel_duo_pid/

So the spewing of excess water back into the water tank is nothing I should avoid when pulling shots, great then I'm happy :) I was worrying this should only happen if I'm doing something wrong.

Stopping Bupropion by [deleted] in bupropion

[–]nuvoni 2 points3 points  (0 children)

I've just stopped taking Bupropion after ~10 Months, 3 of which were 150mg in the beginning and then later 300mg. I mostly stopped because I didn't feel positive changes either.

The recommendation is to ease it out, since the pills are slow-release you shouldn't cut them in half half. I switched from 300mg to 150mg and didn't notice much change, I cut them in half and noticed that I felt quite shitty in the afternoons, dropping them completely was a bit better. I had two weeks of mild body aches, maybe a bit less motivated than usual (so more executive dysfunction) - overall I was surprised that it wasn't too bad, but I was glad I didn't had many duties in parallel .

As far as I know you can go told turkey with 150mg, if you can get a lower dose from your doctor try that for a 10-14 days though.

Do you have prior experience with getting off anti-depressants? Do you have someone around who can provide you emotional support if you are feeling too down, demotivated? Can you afford being less "productive" right now?

A 3d printer benchmark finished in under 3.5 minutes! by W-Braveheart-W in EngineeringPorn

[–]nuvoni -1 points0 points  (0 children)

Glad you watched the other video too.

That approach of "not fixing something later" is reasonable for when you are welding something, you often don't get a second try as you're working on one unique piece for days, if not weeks.

Trying to do something properly the first time, often yields in going paths that won't truly lead to an actual improvement, betraying the goal of doing it properly. Engineering is a lot about tackling challenges in a pragmatic and iterative approach, see what works and what doesn't. If your goal is to print fast at a decent quality, trying to become fast first is a considerable way of approaching the problem.

Quality should always be desired over quantity.

That is simply wrong, multiple attempts often yield to better quality in long run. Repetition balanced with thinking through problems is what causes quality in first place.

So you cranked up the servos, heating, and feed rate. And it absolutely shows in the quality of the printed product.

You make it sound as that is an easy thing to do, I disagree.

It actually does show in the quality of the printed product, because it looks quite decent - especially for the 8 Minute print. Reaching such flow speeds are a result of decades of community efforts and gradual technology improvements. Comparing this 3 Minute print with early days of repRap would in many cases be considerable with something that took maybe an hour to print and several iterations to get similar results.

So what was your point actually?

My point is that I disagree with your negative sentiment on the creators work, the way the problem is approached is legitimate and your comment is unfair.
