Opening up the settings in MakerWare


[Rich Olson] really likes MakerWare and the Makerbot slicer – the software package that comes with every Makerbot – but sometimes he needs to change a few settings. Makerware doesn’t allow the user access to 90% of the setting for slicing and printing, so [Rich] did something about that. He came up with ProfTweak, a tool to change all the MakerWare slicing and printing parameters, giving him precise control over every print.

ProfTweak handles common settings changes such as turning the fan on or off, adjusting the filament diameter, changing feed rate options, and turning your infills into cats. It’s a handy GUI app that should work under Windows, OS X, and Linux, so if you’re running MakerWare right now, you can get up and running with this easily.

One thing [Rich] has been using his new software for is experimenting with alternative filaments. With his Makerbot, he’s able to print in nylon, the wood and stone PLAs, flex PLA, and PET. That’s a lot more material than what the Makerbot natively supports, so we have to give [Rich] some credit for that.

An interview with [David] of Ultimaker


After interviewing the creator of Slic3r and the folks at Shapeways, [Andrew] is back again with his adventures in 3D printer videography and an interview with [David Braam] of Ultimaker

About a year ago, [David] looked at the state of the art in 3D printer control and Replicator G. While Replicator G, along with Pronterface and Repetier-Host both convert 3D models into G-code files as well as control the printer while its squeezing plastic out onto a bed. [David] thought the current state of these RepRap host programs were janky at best, and certainly not the best user experience for any home fabricator. This lead him to create Cura, a very slick and vastly improved piece of host software for the Ultimaker.

Cura isn’t just a fancy front end on an already existing slicer engine; [David] created his own slicing algorithm to turn .STL files into G-code that’s immensely faster than skeinforge. Where skeinforge could take an hour to slice a complex model, Cura does the same job in minutes.

There are also a bunch of cool features available in Cura: you can rotate any part before sending it to the printer, as well as pulling voxels directly from your Minecraft world and sending them to your printer. Very, very cool stuff, and if you’re running a Ultimaker or any other RepRap, you might want to check it out.
