The Maslow $500 CNC kit
No doubt about it, the Maslow CNC is unique. Let’s start with the detail that got your attention. Yes, the price of the Maslow really is $500. Actually, it could be had for as little as $350 if you have a couple of sheets of plywood, a few 2×4’s and a couple of bricks laying around. More about those bricks later.
Next, let’s state the obvious. You get what you pay for. The Maslow is a very simple CNC controlled machine that’s designed for cutting plywood. It comes in kit form, but, looks like it should be simple to complete. You also need to supply your own router. And, being a Kickstarter Project, like all crowd funded projects, there’s potential risk for sponsors. It’s a plus that this team has a track record of delivering on their projects. And, as is the norm, these are projects in the final development phase and so you’ll wait a little while before you can get one.
How does it work?
As you see in the photos of the prototype, it’s pretty basic. Driven by small motors, gears, and chains, a router is moved through the cut in X/Y directions at a slow feed rate. Based upon a hanging plotter design, it’s vertical rather than horizontal. That makes its footprint compact compared to the acres of space a 4×8 horizontal machine takes up in a shop. After checking with the developer, apparently, it’s not hard to make a smaller version, if that’s your choice.
That points to another consideration. At this level, it doesn’t hurt to be a bit geeky to take this on. As always in CNC digital woodworking, you create your drawings in a CAD program and prepare the files for machining with CAM software. But, if you’re on a tight budget there are websites that can do this or free CAM programs available to generate the G-Code that’s needed to run on the Maslow. To run the machine, you need a computer — a laptop should do.
Keep in mind is that there’s no way you can compare the capabilities of the Maslow with what you can do with a serious CNC router. With a solidly built CNC, a woodworker can do serious 2D or 3D machining of solid wood with better than .003 accuracy. The Maslow’s design and simple construction make it best for cutting plywood, MDF and other panel work. Expected accuracy is just .016 or better. That’s about 1/64”. Though hardly precise by CNC standards, it should work for plywood projects without super accurate joinery, jig making, etc. Potentially, it might be good enough for one of my favorite digital woodworking tasks for a CNC: making patterns that you can use for shaping on a router table for repeatable, reasonably accurate, wood furniture parts.
Watching the YouTube videos I got curious and called up the Maslow’s young designer/engineer, Bar Smith for more details. Because the team is located in Port Townsend, near my Seattle area home, I plan on visiting them in the next few weeks to see the machine in action. Looking forward to it. I’ll let you know what I find in future posts.
Now, about those bricks I mentioned earlier. Being a vertical rather than the traditional horizontal CNC machine, you don’t have gravity working in your favor. So, the added weight of the bricks helps push the router into the material being cut and keep the chains tensioned. I told you it was a simple machine.
