Description

Turn your ideas into a reality with the LongMill Benchtop CNC

We designed the LongMill to be rigid, reliable, and easy to put together. With larger extruded aluminum rails, fully supported Y-axis, 1/4″ steel gantries on all axes, and high precision MG-12 type linear guides on the Z-axis, the LongMill is the most powerful CNC router in its class and price point.

Photos shows the latest 30×30 version. 12×12 and 12×30 photos coming soon.

The LongMill helps you take your woodworking and fabrication to the next level. Its range of workable materials include: any species of wood, a variety of plastics, soft metals like aluminum and brass, and a variety of machinable foams and waxes for model making or metal casting.

The LongMill and it’s software works on any computer and connects using standard USB. The total machine working area can be configured as 12″ x 12″, 12″ x 30″, 30″ x 30″.

Every kit comes with all…

  • Hardware, rails, lead screws, and gantries
  • Motors, drivers, and electronics
  • Software (downloadable from our website)
  • Instructions (downloadable from our website)

Assembly only takes a few hours, and can be done with a set of wrenches, allen keys, and a flat head screwdriver. There is absolutely no soldering. We’ve spent hundreds of hours designing and testing the LongMill to ensure that this machine is easy to put together. If you can put together IKEA furniture, then putting together the LongMill will be a breeze.

You will need to get…

  • Your own wasteboard/spoilboard (found at your local hardware store)
  • A router (purchase one from us, use one you already have, or find one at your local hardware store/online)*

*Routers that we supply will be 110V only (North America). If you live in a country which uses a different voltage, please purchase a router in your region. LongMills will come with a power supply that supports both 110V and 220V.

For routers, we recommend the Makita RT0700/RT0701. It’s a reliable and super powerful router that we’ve been using on our CNC machines for years.

Here are some other compatible routers we recommend

  • Bosch Colt
  • Dewalt 611

Don’t see your router listed? Let us know the diameter of your router so that we can make a router mount for you. If you do not send us a diameter we will ship you a mount for the Makita RT0700/RT0701 (65mm).

Please note that routers/spindles which are

  • Over 2.7kg/6lbs
  • Wider than 75mm/3″

May not be compatible (but we’ll try to make it work)

Wasteboard/Spoilboard

What makes this machine unique is that it is designed to be mounted directly to a wasteboard/spoilboard (we recommend using 3/4″ MDF) or other flat surface.

3/4″ MDF is readily available at virtually all hardware and lumber stores such as Home Depot and Lowes (you can even get them to cut it to size).

The LongMill is proudly made in Canada in a way which supports local, growing businesses.

Machine size

These are the approximate dimensions of the machine (without the base). We recommend having a few inches around the feet of the machine to allow for space for wires, electronics, and other bits and bobs. Please note that dimensions can vary slightly.

LongMill 12×12: 23.8″(l) x 23.9″(w) x 13.6″ (h)
LongMill 12×30: 23.8″ (l) x 43.3″ (w) x 13.6″ (h)
LongMill 30×30: 43.5″ x 43.3″ (w) x 13.6″ (h)

Add-ons

You can include add-ons to improve the functionality of the LongMill. These are optional add-ons.

We recommend using the Makita RT0700/RT0701 router 110V ($150CAD) with your LongMill. This router comes with speed control from 10,000 to 30,000RPM and has 1.25HP of power. This router is compatible with up to 1/4″ shank tooling and can be used with a 1/4″ to 1/8″ collet adapter for use with 1/8″ tooling.

The Z-axis independent dust shoe ($45CAD) allows you to attach standard vacuum hoses to your CNC machine, allowing it to suck up dust as it’s cutting, making clean up easier and keeps dust out of the air.

This dust shoe is adjustable in the Z direction, and the front bristles and vacuum hose can be easily unclipped to make it easy to change bits.

The Z-axis touch plate ($35CAD) allows you to “zero” the Z axis against flat surfaces. This makes it easy to very precisely find the distance between the tip of the tool and the surface of your material quickly.

The End Mill Starter Pack ($60) comes with a basic set of end mills to get your started. Each pack comes with:

  • 1/4″ Spiral Up Cut End Mill
  • 1/4″ Spiral Down Cut End Mill
  • 3x 1/8″ Flat End Mill
  • 3x 1/8″ Ballnose End Mill
  • 1/4″ to 1/8″ Collet Adapter

Warranty

The LongMill has a 90 day warranty once it’s received.

We want you to have a great experience with your machine, so if any parts are found to be missing or damaged, please email us. We will ensure that you receive the support you need to restore your LongMill to operating condition or provide a full or partial refund.

You may cancel an order if it has not shipped yet, please contact us if you wish to do so.

We’ll be hosting webinars and creating additional resource videos to help you learn to design and program your CNC machine.

What system requirements are there?

You can run your machine off virtually any modern laptop made in the last 5 years running Windows, Mac OS, and Linux.

We’ve tested our machine with Intel Celeron and AMD Phenom processors with less than 2GB of RAM with no issues (although it is a bit slow).

For any other downloadable CAD or CAM programs that don’t run on the cloud, please check with the software creator for minimum system requirements.

What spindles or routers can I use?

While we recommend the Makita RT0701/RT0700, you can also use other trim/palm style routers. You will be able to let us know what tool you want to use and we will send you the appropriate mount.
