Thanks for the reply, I was genuinely curious and haven't looked into this much beyond window glancing.

I've done some level of flatbed scanning with a ruler to get a known scale and the results have been pretty consistent, but I totally get not wanting to be size limited. I generally print bigger things, which is one of the reasons why I haven't looked at a scanner very hard.

A big reason why I wanted an All-in-one 3D scanner was because I want to reverse engineer objects I see "in the wild" and in museums

That's an interesting use case that I hadn't considered. Makes sense that you want portable and adds the extra challenge of likely not being able to touch the object being scanned.

I agree with you, but it is an amusing premise - even if it is pretty inaccurate. Here's some very quick figures.

The majority of the carbon the human body release is from breathing. Evidently it's about 1 kg of co2 a day or so. All the people on earth combined exhale about 7% of emissions we create from fossil fuels. Even looking at something as small as lawncare, the numbers are super lopsided. Your average lawnmower produces about 40 kg CO2 per hour or use, so if you're (un?)fortunate enough to live somewhere with a lawn, cutting it will produce more CO2 than you do.

That's a good idea, at least that would make questionable technique be our biggest worry.

Did you happen to look into Open Scan? It's reasonably open and is PI based. I don't know a ton about them, but it seems like a viable alternative at first glance.

Thankfully we live in an area with functional sex ed, but sex ed doesn't teach you how to be a good sexual partner. I have nothing against porn, but I imagine it's going to set... very unrealistic expectations of how to behave when getting down.

This will be a fun conversation to have with my kids when they're a bit older.

My rant wasn't aimed at cooked.wiki, more the general state of the web these days.

Weed of the valley! It does smell nice though. We have a bed full of this and mint that I've come to accept for what it is: nice smells, insect friendly, and good for fresh beverages.

Taking a photo of the mini moons at night is an excellent idea.

Bingo. Making a new account somewhere else likely won't help. The only way it would is if all the content OP objects to comes from a single instance and they find another instances that's defederated frrom that source instance.

This seems very similar to the OG all recipies website. Most of their website isn't that bad still. They also support creating an account to save and organize recipies.

I do not understand the fragmentation of the modern web.

Want to send money to a friend? Zelle, Venmo, Cash App, PayPal, Google pay, Apple cash, Popmoney, etc. There's also the growing swath of messaging apps that support peer to peer payment.

Want to buy some second hand clothing? There's Poshmark, Offer Up, Thread Up, Depop, Vinted, Etsy, Grailed, the RealReal, Craigslist, eBay, Facebook Market Place, etc. This is on top of the usual retailers who are also establishing an online presence like Plato's closet, goodwill, etc.

Rinse and repeat for basically any category possible. I'm running into consumer fatigue and I can't imagine it's better for sellers.

I suggest printing a fresh temp tower. My bet is that temperature or retraction is off (have you fiddled with retraction lately) or the filament is super wet.

[–] IMALlama@lemmy.world 1 points 2 days ago (2 children)

Is this a new spool or an old spool? Have you printed this blend of PETG before? What does a temperature tower look like?

Most videoconferencing software these days has dynamic gain to try to accommodate people using non-ideal microphone placement. See if you can turn that off. Audio pressure decreases pretty drastically with distance. Using 10 cm as your microphone to mouth distance, 2.5 m as the distance from your wife's mouth to your microphone, and 60 dB speaking volume, your voice is 30 dB louder than your wife's. That should be enough to make it nearly inaudible / certainly not distracting.

If you're looking to mic shop, get a directional mic. Your current microphone is omnidirectional. A directional microphone will provide even more acoustical attenuation over your wife's voice. A coworker uses one of these for his WFH setup. Look for terms like Cardioid, Supercardioid, and/or Hpercardioid. These are the same microphones used by vocalists on stage.

 
 

Some highlights:

  • Output: Dimmable 12,850 Lux at 3.3' w/ Reflector
  • Built in fan
  • 2700-7500K CCT
  • Full RGB Color Control
  • AC, Optional Battery & USB-C Power
  • CRI 96 | TLCI 94 | SSI 82, 70

The battery connector accepts either a 14.8 or 26 volt pack, so presumably you could wire up a belt mounted battery. Or, you know, buy the official battery.

 
 

Do progress updates, or even ideation posts, fit this community?

Motivations:

  • I don't ton of free time, which means when I finally finish something I'm much more likely to share the end result and not get into the details that eventually got me there. IMO the details, especially the failures along the way, are a lot more interesting than just the result and provide more opportunity for teaching/learning
  • Big projects can be daunting. Talking about the journey will help others be more willing to set off on their own journey
 

I recently installed LDO's version of the Clicky-Clack Fridge Door on my Voron 2.4 350.

My 2.4 is stock in terms of heating other than having the filter, ACM panels, and 2x bed fans.

Takeaways?

  • If you want to make graphs, make sure you have comparable conditions. I was printing during both graphs and the prints had different aspect ratios (before was taller than wide, after was wider than tall). This probably explains why before appears to have heated faster
  • The better sealing door, with thicker acrylic did help chamber temps, but only by 3 degrees C
  • It takes a very long time to heat soak a 350mm^3 chamber, even with 4x bed fans
  • I wish I had a graph before I swapped the ACM panels on, but I don't and the panels are gone :(

I will be lining my panels with radiant insulation in the next week or three and will report back what, if any, changes that makes.

 

Or not, but there was an attempt!

 

Just a cellphone photo that's not particularly well framed, but I liked the contrast between dark trees and the sky. Bonus points for some snow.

 

Bonus points if you post some here too. I'll work on doing better on that myself.

 

Is there such a thing? Some of our plants inevitably grow towards the window quite a bit when I forgot to water them. A very slowly rotating plant stand seems like an obvious solution, but I haven't found any good offerings.

 

I am in the process of buttoning up a Nitehawk conversion on my Voron. I also replaced my extruder thermistor with an OE replacement purchased from a reputable vendor.

Post setup, my heated bed is reading spot on (it's 18.3 C in my basement aka 65 F). I verified that my extruder is also at ambient temperature by wedging a Thermapen under its silicone sock and letting it acclimate for 10 minutes. The I'm not sure why the extruder would be reading high.

I bought a spare thermistor and wired it in. The result was identical.

Thoughts? Ideas? I'm pretty sure I have the Nitehawk and thermistor set up correctly.

As an aside, titling these things is getting harder by the post lol

 

Klipper aborted the print with:

Heater extruder not heating at expected rate Transition to shutdown state: Heater extruder not heating at expected rate See the 'verify_heater' section in docs/Config_Reference.md

Before any of this started,I goobered my original Rapido, so I replaced it with a Rapido 2. It's been in the printer since April, but I haven't done a ton of printing with it. After the replacement, all was well for a while. At some point, Klipper started randomly tripping thermal runaway protection. The spikes were instantaneous, so I suspected a wire break. It wouldn't be my first and they're usually easy to find. I moved the tool head around trying to find it with no success. I pulled apart both cable chains (yay Voron) to look for the wire break and didn't find one. I flipped the printer updside down and connections at the MCU - everything was fine. I went through the hot end and inadvertently pulled the thermistor out of the m3 slug. Here's a stock photo:

Suspecting a potential wire break at the thermistor, I manipulated the wiring to no real effect. Inside the M3 bung was some dried white stuff, which I think was probably Boron Nitride Paste. I bought some more from Slice Engineering and reinstalled the thermistor.

Two things changed after this. First, the terminator seems to be reading lower than it did before. I say this because I have a ton more stringing than I did previously. Second, the temperature is no longer spiking but it is doing this high frequency oscillation thing now.

The oscillation only happens once the printer is moving quickly. If it's still, or moving slowly, things are fine.

Thoughts? I'm suspecting the thermistor, but would like to troubleshoot if possible vs just throwing parts at the printer.
