CNC Pro V3 - Professional Open Source CNC

THE PROFESSIONAL OPEN SOURCE CNC

Stop Wasting Thousands on the Wrong Machine.

Professional Machines

Start at $10,000+ and require tons of experience to operate.

Hobby Machines

Cheap components are quickly outgrown or fail, forcing expensive upgrades.

Reliable

Quality components mean less downtime and more creating. No more replacing worn-out parts every few months. Built to industrial standards with readily available replacements, your CNC Pro V3 keeps running year after year.

SMALL BUT MIGHTY

The CNC Pro Mini Mill

The Mini Mill configuration is great for users in need of a compact and affordable CNC that is capable of machining metals, but still has a relatively large working area. An optional epoxy granite base provides improved vibration dampening when taking aggressive passes in harder metals.

Standard Build: 16" x 16" working area (customizable up to 36" x 36").
Space Efficient: Fits on a 24" deep work bench.
Metal Capable: Machines aluminum, brass, and mild steel.

CAPABLE AND AFFORDABLE

The CNC Pro Router

When configured as a router, the CNC Pro offers a large working area at an extremely affordable price.

Exceptionally strong and durable, the router is ideal for users primarily machining wood, plastics, foam, composites, and sheet goods. It also works great for occasional machining of soft metals, such as aluminum.

Working Area: Up to 50" x 50".
Primary Materials: Wood, plastics, foam, composites, and soft metals (like aluminum).
Build Cost: Extremely affordable for the capability.

HEAVY DUTY PERFORMANCE

The CNC Pro Gantry Mill

Ideal for milling metals, the CNC Pro Gantry Mill is our largest and heaviest machine. Featuring fully machined 9" x 2" aluminum Y axis rails and a steel reinforced epoxy granite base, the Gantry Mill is exceptionally strong.

The Gantry Mill also tips the scales at up to 1,400 pounds (depending on configuration). This added weight helps dampen vibrations when machining metals, and provides an excellent surface finish.

Working Area: Up to 36" x 36".
Metal Ready: Capable of machining harder materials like mild steel.
Heavy Duty: Fully machined 9" x 2" Y axis rails. Steel reinforced epoxy granite base.

TESTIMONIALS

See what CNC Pro users say.

"I have another CNC, that's a commercial machine. And I've had several other CNCs in the past. The CNC Pro is as good as any CNC that I've used. It provides excellent results, was a fraction of the cost of my commercial machine build, and it has been very reliable."

"This was my first CNC, and I had never used one before. I was nervous going into it, because I'm not that techy. But the Knowledge Base has been a tremendous resource. The machine does everything I would hope for and more. And it quickly paid for itself."

Ramon

"I've been using my Conqr CNC to make aluminum molds for fishing lures. It's super efficient and the detail I get is phenomenal. Way better than my old machine, and much higher quality components. Plus, you can't beat the value."

FAQs

Answers to common questions.

The CNC Pro can be configured as a router, a mini mill, or a gantry mill. You can build the CNC Pro in any size up to a 50" x 50" working area (36" x 36" for the Gantry Mill and Mini Mill). Plus, you get all of the part files with the free plans. So you can easily customize the CNC Pro for your specific use case.

It really depends on your build. One of the great things about the CNC Pro is that you can customize nearly every aspect of the machine. Which means that every build is a little bit different.

However, to give you a better idea of how much it will cost, we priced out the cost to build a basic CNC Pro Router in the most common size (with a 30" x 30" working area).

As of this writing, a basic mechanical kit for this configuration will cost around $1,200.

However, this does not include electronics or a spindle. Please also keep in mind that, this is a rough estimate. Prices may fluctuate over time, and there are regional differences between the cost of some parts. Also keep in mind that Gantry Mill and Mini Mill builds will be more expensive, because they have fully machined Y axis rails.

All of the components needed to build a CNC Pro are listed in detail, in the Bill of Materials included with the free plans. In the Bill of Materials, we provide lots of notes regarding selecting different components, as well as links to example vendors.

Most of the components needed to build a CNC Pro are widely available off-the-shelf parts. However, you will need some custom made plates. Part files for these plates are included with the free plans, so you can make them yourself. Or you can order these plates ready-made through our on demand manufacturing network.

You get: (1) all of the part files needed to make the proprietary plates; (2) a bill of materials that provides lots of detailed information about the components you will need and where you can source them; (3) a detailed build video showing how to assemble your CNC Pro; and (4) access to the CNC Knowledge base which includes dozens of videos dedicated to helping you configure and use your CNC Pro.

We've tested machines utilizing each of these setups, and each of these setups can work. However, we prefer ball screws for any axis with a cutting length 50" and under, and rack and pinion or a rotating ball nut assembly for any axis longer than 50".

Timing belts (particularly the smaller belts often used in hobby machines) are not well suited for CNC routers or mills. They work well for situations in which minimal forces act upon the machine (ex. laser cutters and 3D printers). However, timing belts are less than ideal for CNC routers and mills, because of the forces acting upon the end mill during machining operations.

Timing belts are also prone to slipping, which causes lost steps and ruined parts. They further require significant maintenance. Both because they must be kept under sufficient tension to operate properly, and therefore, must be routinely tightened. But, also because they are consumables, often made from rubber, and will see significant wear under heavy use.

However, the biggest issue with timing belts is their lack of mass and rigidity, both of which are important for vibration dampening. Timing belts simply do not have the mass and rigidity needed to aggressive machining operations. As a result, when using hobby grade machines with timing belts, you will likely be limited in your feeds and speeds, as well as the quality of surface finish you can expect.

Lead screws can work well for many applications. In fact, most manually operated mills utilize lead screws. However, lead screws are prone to backlash. This isn't an issue in manually operated mills, because machinists are trained to account for backlash. But, at least at this point in time, robots aren't nearly as capable at accounting for backlash. Also, most hobby grade CNC machines utilize tiny 8mm lead screws. These lead screws are significantly undersized for mill and router applications, and are prone to whipping at higher speeds and longer lengths. To give you some perspective, our ball screws have roughly 4 times the cross sectional area of an 8mm lead screw (roughly 202 mm² vs 805 mm²).
