Get Moving with New Software from OpenBuilds

If you’re reading Hackaday, you’ve probably heard of OpenBuilds. Even if the name doesn’t sound familiar, you’ve absolutely seen something on these pages that was built with their components. Not only is OpenBuilds a fantastic place to get steppers, linear rails, lead screws, pulleys, wheels, and whatever else you need to make your project go, they’re also home to an active forum of people who are passionate about developing open source machines.

As if that wasn’t enough reason to head over to the OpenBuilds website, [Peter Van Der Walt] recently wrote in to tell us about some new free and open source software he and the team have been working on that’s designed to make it easier than ever to get your creations cutting, lasing, milling, and whatever else you could possibly imagine. If you’ve got a machine that moves, they’ve got some tools you’ll probably want to check out.

BlackBox CNC controller

“OpenBuilds CAM” is a web-based tool which imports SVG and DXF files and creates toolpaths for all sorts of cutting, whether your machine does the business using a beam of angry photons or a simple drag knife. The resulting GCode can then be plugged into “OpenBuilds CONTROL”, which as you may have guessed, does the actual controlling of the piece of hardware connected to your computer. There’s no worries about vendor lock in here either, CONTROL will talk to any Grbl-compatible board.

But what if you don’t have a board? Well, it just so happens that OpenBuilds offers a very slick new piece of gear they’re calling the BlackBox. This beefy CNC controller includes a laundry list of features that [Peter] says the team is very excited about, including stepper drivers powerful enough to run NEMA 23 motors. As an interesting note, they’ve actually made the enclosure for the BlackBox out of cleverly solder masked PCBs; a fantastic trick we don’t see often enough.

The video after the break shows the CNC router version of “Hello World” using CAM and CONTROL, and should give you a pretty good idea of the typical workflow. If it looks familiar to you, it might be from our previous coverage of LaserWeb, a similar web-based project spearheaded by [Peter Van Der Walt] a few years back.

How To Make Your Own Springs for Extruded Rail T-Nuts

Open-Source Extruded Profile systems are a mature breed these days. With Openbuilds, Makerslide, and Openbeam, we’ve got plenty of systems to choose from; and Amazon and Alibaba are coming in strong with lots of generic interchangeable parts. These open-source framing systems have borrowed tricks from some decades-old industry players like Rexroth and 80/20. But from all they’ve gleaned, there’s still one trick they haven’t snagged yet: affordable springloaded T-nuts.

I’ve discussed a few tricks when working with these systems before, and Roger Cheng came up with a 3D printed technique for working with T-nuts. But today I’ll take another step and show you how to make our own springs for VSlot rail nuts.
