The Machines Are Getting Cheap. The Toolpaths Are Not.

Desktop 5-axis CNC machines are arriving at sub-$10K prices, but simultaneous multi-axis CAM still costs 20-40% of the machine price per year. Buyers should ask harder questions, and machine vendors should look at open-source CAM.

Something big is happening in desktop CNC. I don’t think most people see the problem hiding inside it.

I work on the CAM workbench in FreeCAD. A lot of people have been sending me Facebook and Kickstarter links to a new wave of desktop milling machines. I’ve spent years thinking about how toolpaths get made and what they cost. So when I look at these machines, I don’t see what the Kickstarter videos show. I see a gap. This post is about that gap.

The trend#

For more than a decade, desktop CNC meant three axes. A spindle moves in X, Y, and Z. It cuts what it can reach from above. Fine machines. Real limits. If you want to reach the other sides of the part, you need to rotate the part or the spindle.

Now watch the axis count climb.

Four-axis is going mainstream right now. The two biggest desktop CNC campaigns in Kickstarter history closed within weeks of each other in late 2025. The Makera Z1 raised $10.2 million. It’s four-axis ready and starts at $899. The Nestworks C500 raised $12.2 million with an optional simultaneous fourth axis. Three-axis machines still dominate the installed base, but four-axis is where the growth is.

Five-axis is the wave behind it. Pocket NC proved a desktop five-axis machine could exist back in 2015. The trade press called it “5-Axis 4 Grand” because the idea was absurd until it wasn’t. Then, in a single twelve-month window from mid-2025 to mid-2026, four desktop machines claiming true simultaneous five-axis launched or pre-launched: the InfiMaker K1, the IFMAKER M5, the Xhorse WM-100, and the TOPFAB TF500. Every one of them is priced between $5,200 and $8,600.

To understand how strange those numbers are, you need the old numbers. Entry into five-axis machining used to start around $150,000 and climb fast. When Haas released the UMC-500 at roughly $166,000, the industry considered it disruptively cheap. That was 2017. Nine years later, companies are promising the same capability, albeit at a much smaller scale, for the price of a nice laptop and a vacation.

Tormach deserves a mention here. Years ago they bet there were customers who wanted machines far cheaper than commercial iron but far better than hobby routers. They were right, and they built a real business in the $10,000 to $40,000 range. Part of how they hit those prices was building PathPilot on open-source machine control. Keep that thought. We’ll come back to it.

One honest caveat before we go on. The five-axis wave is, right now, a wave of campaigns. Almost none of these machines have shipped. Pocket NC is still the only desktop five-axis with a delivery track record. The trend is real. The machines are still mostly vapor.

The promise#

The marketing for all of these machines makes the same promise: this will be as easy as 3D printing.

That’s not my paraphrase. “The first desktop CNC that’s as easy as 3D printing” was the literal tagline on the original Carvera campaign in 2021. The 2026 machines escalate it. One-click CAM. Toolpaths from a text prompt. “No CNC background needed.”

Each machine ships with its own “studio” software. The demo videos are genuinely impressive. Smooth five-axis motion. Beautiful surfaced parts. The target customer is an artist or a maker, not an engineer, and the message is clear: press start and walk away.

I want that future to be real. But there’s a chain of dependencies the videos skip over.

The catch#

A machine can only cut what its toolpaths tell it to cut. Toolpaths come from CAM software. So the machine’s utility is limited by the CAM you can afford.

The bundled studio software is where this gets uncomfortable. Nobody outside these companies has verified what the applications can actually do, because the machines haven’t shipped. Look closely at what the demo videos actually show. It’s almost always 3D surfacing. Take a mesh, wave a ball endmill over every point of it, and a figurine emerges. Surfacing is beautiful, and it’s also the easiest toolpath to generate automatically. One generic operation. That’s why the “easy as 3D printing” pitch works — for that one kind of part.

Functional parts are a different problem. A bracket has flat mating faces, bores at dimension, tapped holes, and a tolerance stack. Machining it means choosing the right operations, ordering them correctly, selecting the right tools, and sequencing the setups. No text prompt gets you there. This is the work CAM software actually exists to do, and it’s the work...
