DIY Shapeoko 3 Enclosure

Setting up a desktop CNC brings along two additional problems that need to be resolved – noise and dust. [Nick] upgraded from a Shapeoko2 to the Shapeoko3 and decided to build a fresh dust and noise proof enclosure for his CNC , and it turned out way better than he had anticipated.

When trying to build something like this, aluminium extrusions seem like the obvious choice for the structure. Instead, he opted for low-cost steel frame shelving units. The 3mm thick steel frame results in a nice rigid structure. The top and bottom were lined with 18mm thick MDF panels. For the two sides and back, he choose 60mm noise dampening polyurethane foam lined with 6mm MDF on both sides, and held together with spray adhesive and tight friction fit in the frame.

The frame was a tad shallower and caused the spindle of the Shapeoko3 to stick out the front. To take care of this, he installed an additional aluminium frame to increase the depth of the enclosure. This also gave him a nice front surface on which to mount the 10mm thick polycarbonate doors. The doors have magnetic latches to hold them close, and an intentional gap at the top allows air to enter inside the enclosure. A 3D printed outlet port was fixed to the side wall, where he can attach the vacuum hose for dust collection. The final step was to add a pair of industrial door handles and a bank of blue LED strip lights inside the enclosure for illumination.

It’s a simple build, but well executed and something that is essential to keep the shop clean and dampen noise.

X-Carve, The Logical Upgrade To A Shapeoko

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 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.
