Remove ringing by tuning acceleration and junction deviation - step by step guide

1 Comment
From: Teaching Tech
Duration: 17:19

Tuning your 3D printer acceleration is the next step in getting the most of your machine. With this and junction deviation, you can find a nice compromise between speed and surface quality, eliminating ringing. In this video I calculate and tune to match a very high print speed, but this works the same for any feedrate.

Testing the fastest an extruder/hot end combo can push through filament is pretty interesting, and I may repeat this test for future upgrade videos.

Meet OnHub: a new router for a new way to Wi-Fi

7 Comments and 8 Shares
Ugh...not again. You get home at the end of the day, and sit down to stream a new movie or upload vacation photos — and your Wi-Fi slows to a crawl or just stops working. Instead of relaxing in front of the screen or sharing those photos with friends, you spend it unplugging and re-plugging cords, trying to decipher blinking lights, or contemplating a call to customer support.

While we count on Wi-Fi more than ever to be entertained, productive, and stay connected, we’re streaming and sharing in new ways our old routers were never built to handle. So today, with our partner TP-LINK, we’re launching OnHub, a different kind of router for a new way to Wi-Fi. Instead of headaches and spotty connections, OnHub gives you Wi-Fi that’s fast, secure, and easy to use.



Designed for the Home
Many of us keep our router on the floor and out of sight, where it doesn’t work as well. We replaced unruly cords and blinking lights with internal antennas and subtle, useful lighting, so you’ll be happy placing OnHub out in the open, where your router performs its best.

Starts Fast, Stays Fast
During setup, OnHub searches the airwaves and selects the best channel for the fastest connection. A unique antenna design and smart software keep working in the background, automatically adjusting OnHub to avoid interference and keep your network at peak performance. You can even prioritize a device, so that your most important activity — like streaming your favorite show — gets the fastest speed.

A simple mobile app
OnHub makes it simple to set up and manage your Wi-Fi, all from the Google On app, available on Android or iOS. The Google On app tells you how much bandwidth your devices are using, lets you run a network check, and if there’s an issue with your Wi-Fi, the app offers suggestions to help. And, instead of lost passwords and sticky notes, it even reveals your password with a single tap and lets you text or email it to friends.

Just gets better
OnHub automatically updates with new features and the latest security upgrades, without interrupting your connection. In the future, OnHub can support smart devices that you bring into your home, whether they use Bluetooth® Smart Ready, Weave, or 802.15.4. We also plan to design new OnHub devices with other hardware partners in the future. Stay tuned for news from our second partner, ASUS, later this year.

Starting today, OnHub is available for pre-order for $199.99 from online retailers in the U.S. including the Google Store, Amazon, and Walmart.com. It will be available for sale in retail stores in the U.S. and in Canada in the coming weeks.

At the end of the day, we want our Wi-Fi to just work, so that we can do all the things we love to do online. Here’s to Wi-Fi with the reliability, speed, and security you want at home, without the frustrations you don’t.

I saw this elsewhere, but it's worth repeating...

Just connect your Google router to your Google fiber connection and connect to it with your smartphone or laptop running a Google operating system and Google browser. Visit your Google home page (using Google's DNS servers, of course) to read your Google Mail, or perhaps catch up on the news with Google News, or use Google+ to see what your friends are up to, or get a little work done on Google Docs. Should you do some Google searches and end up on some non-Google sites, don't worry - you're still safe under the watchful eye of Google AdSense and Google Analytics. What have you got to be so paranoid about?

Someday soon we will all be making the conscious choice, "do I want to have my complete information and records with one company, or do I want to have three or four companies have 70% of my information apiece?"

@srsly: I really hope you're right but I don't see much evidence of this happening so far. Far too many people are far too happy to put all their data in the hands of a single company with no thought of the risks.

I trust literally zero products Google makes anymore, I'm not about to hand them my physical router. Buyer Beware.

It’s Time to End “Traditional Gay Marriage”

1 Share
One of the nuttier arguments against same-sex marriage — and there’s a hotly contested battle for that distinction — is that gay people already have the right to marry. If they want to, they can marry someone of the opposite … Continue reading
