My apologies if you speak the Queen’s English since that title probably has a whole different meaning to you than I intended. In fact, I’m talking about Git, the version control system. Last time I talked about how the program came to be and offered you a few tutorials. If you are a dyed-in-the-wool software developer, you probably don’t need to be convinced to use Git. But even if you aren’t, there are a lot of things you can do with Git that don’t fit the usual mold.
The Prusa i3 Mk 2 is the hotness in consumer-grade, quality 3D printing right now. And things just keep getting more interesting. We caught up with Josef Průša at Maker Faire Bay Area this weekend to see the multi-material extruder in its final form. It’s an upgrade to the Mk 2 which allows a single hot end to print in four different materials, be it different colors or different types of filament.
A plasma cutter is probably top of every metalworker’s short list of dream tools. From freehand curves to long straight cuts, nothing beats a plasma cutter for getting the creative juices flowing. Unfortunately, there’s also the jet of superheated metal blasting through the workpiece to deal with, which is the reason behind this shop-built plasma cutting workstation.
[Regalzack] looks like he had a couple of design goals in mind for his table. A solid work surface isn’t a great idea for plasma cutting, so he designed the top as a grid of replaceable steel slats. Underneath is a hopper to collect the slag, both for neatness and for fire safety. The table top and hopper live on a custom-built wheeled steel frame, and the lower shelf provides plenty of room for his Lincoln 375 plasma rig. With hooks for cables and a sturdy ground clamp tab, the whole thing is a nicely self-contained workstation. The video below shows the build and some of the fabrication techniques [Regalzack] used; we were especially taken by the clever way he cut the slots for the table slats.
