Autodesk Moves EAGLE To Subscription Only Pricing

January 19, 2017 by 410 Comments

EAGLE user? We hope you like subscription fees.

Autodesk has announced that EAGLE is now only available for purchase as a subscription. Previous, users purchased EAGLE once, and used the software indefinitely (often for years) before deciding to move to a new version with another one-time purchase. Now, they’ll be paying Autodesk on a monthly or yearly basis.

Lets break down the costs. Before Autodesk purchased EAGLE from CadSoft, a Standard license would run you $69, paid once. The next level up was Premium, at $820, paid once. The new pricing tiers from Autodesk are a bit different. Standard will cost $15/month or $100/year, and gives similar functionality to the old Premium level, but with only 2 signal layers. If you need more layers, or more than 160 cm^2 of board space, you’ll need the new Premium level, at $65/month or $500/year.

This is a bad deal for the pocket book of many users. If you could have made do with the old Standard option, you’re now paying $100/year instead of the one-time $69 payment. If you need more space or layers, you’ll likely be up to $500/year. Autodesk also killed the lower cost options for non-commercial use, what used to be a $169 version that was positioned for hobbyists.

The free version still exists, but for anyone using Eagle for commercial purposes (from Tindie sellers to engineering firms) this is a big change. Even if you agree with the new pricing, a subscription model means you never actually own the software. This model will require licensing software that needs to phone home periodically and can be killed remotely. If you need to look back at a design a few years from now, you better hope that your subscription is valid, that Autodesk is still running the license server, and that you have an active internet connection.

On the flip side of the coin, we can assume that Eagle was sold partly because the existing pricing model wasn’t doing all it should. Autodesk is justifying these changes with a promise of more frequent updates and features which will be included in all subscriptions. But sadly, Autodesk couldn’t admit that the new pricing has downsides for users:

“We know it’s not easy paying a lump sum for software updates every few years. It can be hard on your budget, and you never know when you need to have funds ready for the next upgrade.”

In their press release, they claim the move is only good for customers. Their marketing speak even makes the cliche comparison to the price of a coffee every day. Seriously.

[Garrett Mace] summarized his view on this nicely on Twitter: “previously paid $1591.21 for 88 months == $18.08/mo. Moving to $65/mo? KICAD looks better.”

We agree [Garrett]. KiCad has been improving steadily in the past years, and now is definitely a good time for EAGLE users to consider it before signing on to the Autodesk Subscription Plan™.

Variable Thickness Slicing For 3D Printers

November 3, 2016 by 25 Comments

With proper tuning, any 3D printer can create exceptionally detailed physical replicas of digital files. The time it takes for a printer to print an object at very high detail is another matter entirely. The lower the layer height, the more layers must be printed, and the longer a print takes to print.

Thanks to [Steve Kranz] at Autodesk’s Integrated Additive Manufacturing Team, there’s now a solution to the problem of very long, very high-quality prints. It’s called VariSlice, and it slices 3D in a way that’s only high quality where it needs to be.

The basic idea behind VariSlice is to print vertical walls at a maximum layer height, while very shallow angles – the top of a sphere, for example – are printed at a very low layer height. That’s simple and obvious; you will never need to print a vertical wall at ten micron resolution, and fine details will always look terrible with a high layer height.

The trick, as in everything with 3D printing, is the implementation. In the Instructable for VariSlice, it appears that the algorithm considers the entire layer of an object at a time, taking the maximum slope over the entire perimeter and refining the layer height if it’s necessary. There’s no weird stair stepping, overlapping layers of different thicknesses, or interleaving here. It’s doing automatically what you’d normally have to do manually.

Nevertheless, the VariSlice algorithm is now one of Autodesk’s open source efforts, just like the Ember resin printer used in the example below. The application for this algorithm in filament-based printers is obvious, though. The speed increase for the same level of quality is variable, but the time it takes to print some very specific objects can be up to ten times faster. Whether or not this algorithm can be integrated into Cura or Slic3r is another matter entirely, but we can only hope so.

The Future Of Eagle CAD

July 5, 2016 by 110 Comments

Last week, Autodesk announced their purchase of CadSoft Eagle, one of the most popular software packages for electronic design automation and PCB layout.

Eagle has been around for nearly thirty years, and has evolved to become the standard PCB design package for electronic hobbyists, students, and engineering firms lead by someone who learned PCB design with Eagle. The reason for this is simple: it’s good enough for most simple designs, and there is a free version of Eagle. The only comparable Open Source alternative is KiCad, which doesn’t have nearly as many dedicated followers as Eagle.  Eagle, for better or worse, is a standard, and Open Source companies from  Sparkfun to Adafruit use it religiously and have created high-quality libraries of parts and multiple tutorials

I had the chance to talk with [Matt Berggren], former Hackaday overlord who is currently serving as the Director of Autodesk Circuits. He is the person ultimately responsible for all of Autodesk’s electronic design products, from Tinkercad, 123D, Ecad.io, and project Wire, the engine behind Voxel8, Autodesk’s 3D printer that also prints electronics. [Matt] is now the master of Eagle, and ultimately will decide what will change, what stays the same, and the development path for Eagle.

The EAGLE Has Landed: At Autodesk!

June 29, 2016 by 82 Comments

The selloffs continue at Farnell! We’d previously reported that the UK distributor of electronics parts was being sold to a Swiss distributor of electronics parts. Now it looks like they’re getting rid of some of their non-core businesses, and in this case that means CadSoft EAGLE, a popular free-for-limited-use PCB layout suite.

But that’s not the interesting part: they sold EAGLE to Autodesk!

Autodesk had a great portfolio of professional 3D-modeling tools, and has free versions of a good number of their products. (Free as in beer. You don’t get to see the code or change it.) By all accounts, the professional versions of their tools are very professional if you can afford them, and the trial versions are still useful. This makes EAGLE slot very nicely into their business model, filling a hole (PCB design) in their toolchain.

What does this mean for those of you out there still using EAGLE instead of open-source alternatives? (We haven’t used EAGLE since KiCAD got good a couple years back.) Beats us! Care to speculate wildly? That’s why we have a comments section. Go! In the mean time we hope to have more info for you directly from Autodesk soon so stay tuned to the front page.

RetroFab: Machine Designed Control Of All The Things

May 14, 2016 by 10 Comments

On the Starship Enterprise, an engineer can simply tell the computer what he’d like it to do, and it will do the design work. Moments later, the replicator pops out the needed part (we assume to atomic precision). The work [Raf Ramakers] is doing seems like the Model T ford of that technology. Funded by Autodesk, and as part of his work as a PhD Researcher of Human Computer Interaction at Hasselt University it is the way of the future.

The technology is really cool. Let’s say we wanted to control a toaster from our phone. The first step is to take a 3D scan of the object. After that the user tells the computer which areas of the toaster are inputs and what kind of input they are. The user does this by painting a color on the area of the rendering, we think this technique is intuitive and has lots of applications.

The computer then looks in its library of pre-engineered modules for ones that will fit the applications. It automagically generates a casing for the modules, and fits it to the scanned surface of the toaster. It is then up to the user to follow the generated assembly instructions.

Once the case and modules are installed, the work is done! The toaster can now be controlled from an app. It’s as easy as that. It’s this kind of technology that will really bring technologies like 3D printing to mass use. It’s one thing to have a machine that can produce most geometries for practically no cost. It’s another thing to have the skills to generate those geometries. Video of it in action after the break.  Continue reading “RetroFab: Machine Designed Control Of All The Things” →

Autodesk Open Sources Ember 3D Printer

September 29, 2015 by 20 Comments

If you’ve ever been interested in what goes on inside a (roughly) $6000 DLP stereolithography printer, you might want to check out the recent announcement from Autodesk that open sources their electronics and firmware for their Ember 3D printer. The package includes the design files and code for their controller (which is more or less a BeagleBone black with a USB hub, and more memory. It also has two AVR controllers for motor and light control.
