‘Member StarCraft? Ooooh, I ‘member StarCraft. The original game and the Brood War expansion are now free. A new patch fixes most of the problems of getting a 20-year-old game working and vastly improves playing over LAN (‘member when you could play video games over a LAN?) And you thought you were going to have free time this week.

About a year ago, [Mark Chepurny] built a dust boot for his Shapeoko CNC router. The SuckIt (not the best possible name, by the way) is an easy, simple way to add dust collection to an X-Carve or Shapeoko 2. The folks at Inventables reached out to [Mark] and made a few improvements. Now, the renamed X-Carve Dust Control System. It’s a proper vacuum attachment for the X-Carve with grounding and a neat brush shoe.

I don’t know if this is a joke or not. It’s certainly possible, but I seriously doubt anyone would have the patience to turn PowerPoint into a Turing Machine. That’s what [Tom Wildenhain] did for a lightning talk at SIGBOVIK 2017 at CMU. There’s a paper (PDF), and the actual PowerPoint / Turing Machine file is available.

System76 builds computers. Their focus is on computers that run Linux well, and they’ve garnered a following in the Open Source world. System76 is moving manufacturing in-house. Previously, they’ve outsourced their design and hardware work to outside companies. They’re going to work on desktops first (laptops are much harder and will come later), but with any luck, we’ll see a good, serviceable, Open laptop in a few year’s time.

Remember last week when a company tried to trademark the word ‘makerspace’? That company quickly came to their senses after some feedback from the community. That’s not all, because they also had a trademark application for the word ‘FabLab’. No worries, because this was also sorted out in short order.

Clear The Air Around Your CNC Router With A Custom Dust Shroud

December 18, 2016 by Dan Maloney 11 Comments

Using a CNC router is a dusty business if your material of choice is wood. Sure, you can keep things tidy by chasing the cutter around the table with a shop vac, but that sort of takes the fun out of having a machine that can make cuts without you. The big boy machines all have integrated dust collection, and now you can too with this 3D-printed CNC router dust shoe.

Designed specifically for the X-Carve with a DeWalt 611 router, [Mark Edstrom]’s brush is a simple design that’s almost entirely 3D printed. The shroud encloses the router body and clamps to the mounting bracket, totally surrounding the business end of the machine. The cup is trimmed with a flexible fringe to trap the dust and guide it to the port that fits a small (1-1/4″ diameter) shop vac hose. The hose is neatly routed along the wiring harness, and the suction is provided by a standard shop vac.

Files for the cup are up on Thingiverse; we suspect it’d be easy to modify the design to work with other routers and dust collectors. You might even find a way to shroud a laser cutter and capture the exhaust with a DIY filter.

Inventables Releases Improved X-Carve CNC Router

September 1, 2016 by Brian Benchoff 37 Comments

Introduced last year as an improvement on the very popular Shapeoko CNC router, the X-Carve by Inventables has grown to be a very well-respected machine in the community. It’s even better if you throw a DeWalt spindle on there, allowing you to cut almost everything that’s not steel. With a recent upgrade to the X-Carve, it’s even more capable, featuring the best mods and suggestions from the community that has grown up around this machine.

The newest iteration of the X-Carve features higher power drivers, better rigidity, and a heat sink for the spindle. That last item is an interesting bit of kit – routing takes time, and a 1¼HP motor will turn electricity into heat very effectively.

In addition to the 500mm square and 1000mmm square routers previously available, there’s a new, 750mm square machine available. All machines feature a new electronics box for the X-Carve, the X-Controller. This ‘brain box’ is a combined power supply, stepper driver, and motion controller built into a single box. The stepper drivers are able to supply 4A to a motor, is capable of 1/16 microstepping, and has connections for limit switches, spindle control speed, a Z probe, and outputs for vacuums or coolant systems. The underlying controller is based on grbl, making this brain box a very solid foundation for any 3-axis CNC build. The ‘brain box’ format seems to be the way the hobbyist CNC market is going, considering the whispers and rumors concerning Lulzbot selling their Taz6 brainbox independently from a 3D printer.

The new X-Carve is available now, with a fully-loaded 1000mm wide machine coming in at about $1400. That’s comparable to many other machines with the same volume, unlike the Chinese 3040 CNC machines, you don’t need to find an old laptop with a parallel port.

Hackaday Prize Semifinalist: CNC Becomes Pick And Place

September 28, 2015 by Brian Benchoff 25 Comments

In the 80s and 90s, building a professional quality PCB was an expensive proposition. Even if you could afford a few panels of your latest board, putting components on it was another expensive process. Now, we have cheap PCBs, toaster-based solder ovens, and everything else to make cheap finished boards except for pick and place machines. ProtoVoltaics’ semifinalist entry for the Hackaday Prize is the answer to this problem. They’re taking a cheap, off-the-shelf CNC machine and turning it into a pick and place machine that would be a welcome addition to any hackerspace or well-equipped garage workshop.

Instead of building their own Cartesian robot, ProtoVoltaics is building their pick and place around an X-Carve, a CNC router that can be built for about $1000 USD. To this platform, ProtoVoltaics is adding all the mechanics and intelligence to turn a few webcams and a CNC machine into a proper pick and place machine.

Among the additions to the X-Carve is a new tool head that is able to suck parts out of a reel and spit them down on a blob of solder paste. The webcams are monitored by software which includes CUDA-accelerated computer vision.

Of course a pick and place machine isn’t that useful without feeders, and for that, ProtoVoltaics built their own open source feeders. Put all of these elements together, and you have a machine that’s capable of placing up to 1000 components per hour; more than enough for any small-scale production, and enough for some fairly large runs of real products.

You can check out some of the videos for the project below.

X-Carve, The Logical Upgrade To A Shapeoko

March 3, 2015 by Brian Benchoff 33 Comments

When it comes to small CNC carving machines for hackerspaces and extremely well-equipped garages, the Shapeoko, or something like it, has been the default machine. It’s dead simple – a Dremel attached to linear rails – and is useful for everything from milling PCBs to routing complex woodworking project to plotting designs with a pen. Now, [Bart Dring], the guy behind the Buildlog.net lasers and Inventables have teamed up to create the next generation of carving machines. It’s called the X-Carve, and while it’s fully compatible with the Shapeoko 2, it adds a few improvements that make for a much better machine.

The X-Carve does away with the Dremel-based spindle and replaces it with something that can produce torque. There’s a 24VDC spindle in the stock arrangement that will give you speed control through Gcode. There is, of course, adapters to fit the Dewalt and Bosch routers most commonly used in these types of machines.

As far as the gantry goes, the X and Y axes are makerslide; no change there. The Z axis leadscrew has an optional upgrade to Acme threaded rod, an improvement over the M8 threaded rod found in just about every other DIY machine kit. The entire machine is basically all the upgrades a Shapeoko should have, with stronger corners, NEMA 23 motors, and increased rigidity.

There are a few versions of the X-Carve, ranging from an upgrade kit to the Shapeoko 2 to a fully loaded kit with a square meter of machine space. The big, high-end kit ships for around $1250, but a smaller kit with 500mm rails, NEMA 17s, and threaded rod lead screw is available for around $800.

[Bart] and [Zach], the founder of Inventables sat down and shot a video going over all the features of the X-Carve. You can check that out below.
