Announcing Cura 2.7

Announcing Cura 2.7

We are proud to announce the latest stable release Cura 2.7. Our software team worked really hard to improve the user interface, cramp it up with new features and fix some bugs.

The feedback we received following Cura 2.7 Beta was really helpful and we could not have made the stable version without you.

 

So, what is new in Cura 2.7?

Ironing has been implemented. Ironing, aka NeoSanding from our super-user @Neotko pushes a heated nozzle over the top layer with a significantly reduced extrusion rate to fill in any gaps and make the top surface incredibly soft. You can find it in the experimental section.

Print thin walls. You can now print walls up to half of your nozzle size. I wonder if this would mean @Labern will get some competition with his minuscule power drill. [link]

Prime tower purge volume. By fine-tuning the amount of filament you prime when wiping the prime tower, you reduce the chance of your prime tower failing during your print by preventing under extrusion. Interested to give this a chance? You can find the setting under ‘prime tower purge volume’ under ‘dual extrusion’.

SolidWorks plugin. This plugin enables SolidWorks format files to be directly imported straight into Cura. They are automatically converted into an .STL and you can use Cura to prepare your file for 3D printing.

Extruder per feature. Assign print features like walls, infill, skin etc to a specific extruder.

Some examples:

This model was printed in an experimental combination; black ABS with an outer skin of blue TPU 95a. This can be used for practical purposes, such as increased grip on a handle.

A print core with a 0.8 mm nozzle has been assigned to print infill and inner walls here, while a 0.4 mm nozzle has been assigned to print all other features with more detail. This combination ensures significantly reduced print times.

Assigning an extruder using a different color allows for aesthetic effects with minimal material switches. This item is printed in red PLA, with a top surface in black PLA.

You can find a full list of release notes via this link.

More information about Cura 2.7 is in our blog.

Besides going in-depth with the new theme it also explains some pretty nifty improvements we made to PVA supports which can lead up to 30% time saving on the gyro model, and 40% PVA savings.

Ready? Download Cura 2.7 here.

And as always, we would love to hear from you. Give us your thoughts and experiences and we'll give you more Cura!

Please fix the anti-virus definitions...I had to battle it out with my anti-virus software to install this. Thank you

[LePaul 331]

Ok well this qualifies as really odd.

Installed 2.7 (did not install beta on this laptop)

Setup a print and "Print with Octoprint", which has always worked good.

Once bed was to temp, it immediately raised bed and tried to commence printing. Didn't try to purge material (which it couldn't, the nozzle was at 49C)

Thought it was a fluke but tried it again....did the same thing again.

What is the GCode flavor set to? Did you change your start gcode at all?

[LePaul 331]

Oh let's check....it had been Marlin but the upgrade might've changed that.

Yes...it went to Ultimaker2

I'll set it back!

[leliep 28]

Thanks for making it available, but on my MacBook with MacOS Sierra 10.12.6 it always crashes during startup. This behavior was already with the beta version and it persists after reboot. Right now I am working with Cura 2.6.x, but would like to change to 2.7

Thanks again, -pl

Just to whome it may concern :-)

The SolidWorks Plugin is also working with SW2013 parts & assamblies...

Hello,

I downloaded the 2.7 CURA version for windows, installed it, but it won´t launch..it starts going, but crashes..

[leliep 28]

Today I was able to start Cura 2.7 once and send a job to my UM3. When the print was finished, Cura had crashed.

When I try to start it again, it always crashes now.

When I open the Cura package and start MacOS/cura, I get the following message in the terminal window:

The only one that I have is one from the night before, please see:

Right now Cura can be started without a problem, so the problem ist sometimes there and sometimes not. Strange.

Seems the problem has nothing to do with the CA trust, because right now it works despite the CA error msg on the console:

Could it have something to do with the Cura printer access?

I was able to start Cura 2.7 from another fresh account on my MacOS based MacBook and prepare a print without any problem, not yet connected a printer.

As soon as I then tried to connect Cura to my UM3 (via ethernet, local network with 192.168.10.x) address, Cura crashed immediately. Was able to reproduce this several times.

I have a cura stderr.log from this event, can send it to whom it concerns... (too long to post here)

[IdleGoose 0]

I'm sticking with 2.6.2 With 2.7 I had more starup fails than previously, and unable to print via USB. (Yes, i also tried uninstalling 2.6.2 and reinstalling 2.7 clean) Let me know if you would like system specs or other information.

[leliep 28]

Further testing leads to the conclusion that the (original Apple A1433 EMC2590) Thunderbold Gigabit Ethernet Adapter is crashing Cura 2.7 on my MacBook pro with MacOS 10.12.6 (no problems with Cura 2.6): when I connect to the network via my Thunderbold Gigabit Ethernet adapter, Cura crashes after several (about 6) seconds, producing a formidable stack dump.

This behavior ist reproducible on intent.

Using the network via WiFi or via an USB-Ethernet Adapter is working w/o any problem.

I just did a fresh install of Cura 2.7 on my new Macbook with macOS Sierra (10.12.6). It seems like Cura is automatically creating an 'AppData' folder in my home folder. The folder contains a 'Local/cura' folder with the log files 'stderr.log' and 'stdout.log'. This folder and files are always recreated when Cura is loaded.

Is this intended or just a hard-coded Windows path?

That's a bug you found there...

Ok, then I will open an issue on GitHub...
