Check out our recommended products tabs for an ideal set up, but note the following ARE NOT included with your order:
- Computer or laptop
- Router*
- End mills or bits
- Work surface (e.g. MDF sheet)
- Screw drivers, standard bits or drill for assembly
Please Note: Power supplies are 110V only, (North America). If you live in a country with 220V/240V power, our standard LongMill MK2 power adapter must use a transformer with a rating above 300 watts to convert your power to 110V/120V. Routers that we supply will be 110V only (North America). If you live in a country that uses a different voltage, please purchase a router in your region.
For routers, we recommend the Makita RT0700/RT0701. It’s reliable, powerful, speed-adjustable to a large range (10-30K RPM), and its uniform outer body allows for versatile z-axis mounting. We’ve been using the Makita on our CNC machines for years. The LongMill MK2 comes free as standard with a 65mm router mount, which is compatible with the Makita RT0700/RT0701 and most variations of this router design.
Some photos may contain items for illustrative purposes, such as routers, work surfaces, dust shoes or additional shelving. There may also be cosmetic differences between the machine in the photo and the production version of the LongMill.
We designed the LongMill to be the best hobby CNC router in its class, offering rigidity, and reliability. With large extruded aluminum rails, fully supported Y-axes, 1/4″ steel gantries on all axes, high power NEMA 23 motors, and high precision MG-12 type linear guides on the Z-axis, the LongMill MK2 is the most powerful CNC router in its class at its price point.

FAQs
Choosing an LongMIll vs an AltMill
https://youtu.be/7-sgkZQwWMk
What materials can it cut?
The LongMill is primarily designed for cutting wood but is capable of cutting foam, plastic, and soft metals such as aluminum and brass.
Where can I buy end mills and other tooling?
End mills and bits are available on sale on our website as well as online such as Amazon and Ebay, or at your local hardware store such as Home Depot or Lee Valley.
What software can you use with the LongMill?
The LongMill is compatible with dozens of free and paid CAM software. The LongMill is compatible with standard G-code. You can check out our resources page at www.sienci.com/resources and look under the software tab. 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.
Will there be 4th or 5th axis support?
In the immediate future, there will not be 4th or 5th axis support for the LongMill. If you would like to implement an additional axis to your machine, we encourage users to try creating their own and sharing it with the community!

My first experience with a CNC machine and I feel I made the right choice. Sienci Labs is a helpful company that was very quick to respond to my inquiry. I have made several items from various 2d to 3d designs and after a short learning curve, the machine is reliable and fun to use. From routing to using the laser, I am sure it will keep me busy for years to come.

I really like the machine. I had some difficulty in getting the y axis to move in tandem with each other. It took me three assembly/disassembly tries before I got it to work. A little frustrating but necessary. It currently is working fine. Your online resources helped in working through the problems. I have the laser on and trying to learn it. I have completed a sign as a gift using the router and a Christmas ornament using the laser. Overall I am extremely happy with your products. What would be on my wish list? A more powerful laser to cut down on time. I have a full time job and can only work at night and weekends so a 10-12 hour job is tough to run. All things being taken into account, you have a great product and I am/will be recommending it to my friends and associates. I would purchase your product again.

Ordered my mk2 30×48 machine after doing a lot of research online. The ordering process is easy and when the boxes arrived everything there(no missing pieces). The packaging was next to none(awesome).These guys know what their doing! Assembly was a breeze, between the detailed instructions and the videos it was a piece of cake. I’ve started making signs but this machine has opened my creative side and the sky’s the limit with what I can do. Exciting times ahead :o)
The Longmill Facebook group is a wealth of knowledge and everybody is helpful.
All around a great experience and I would (and have) recommend Longmill to friends.
Keep up the good work!

So far I love the CNC. the best part of the experience is your customer service! I had a small issue with the CNC and was given instructions on how to fix it. Also, and more importantly, my laser wasn’t working correctly (user error). Ikenna FaceTimed with me to help me understand. Best customer service, period. I have recommended you to friends.

I was hoping to get it sooner as I have two knee surgeries back to back. So I haven’t had a chance to get it built before that started. It was held up at customs. As soon as I can, I plan on getting busy with it. I’ve been a cnc machinist and programmer for 34 years and I’m looking forward to using the machine. I teach delmia software and camworks. I have made a post for use with Delmia makers software and I’ve been working to make a full simulation with kinematics in Delmia. I also bought the Vcarve pro software and learning that too. I plan on trying to purchase your 4th axis and maybe another machine….pretty excited to use it. Otherwise everything has been fine so far.

This machine is all that it claims to be. I was impressed by how solid and how precise the manufacturing is. It was easy to assemble due to the very complete instructions provided. I have not needed any customer service regarding this machine so I have no opinion about it from experience. So far I have made a small name plaque, a box jointed drawer for holding my cnc accessories, dog bowl stands and a logo medallion. I also have the laser attachment. I have etched tiles and coasters with it and also put a grid on the cnc spoilboard. I still have a lot to learn and plan to make a great variety of things.
To be fair there are a few minor issues I came across. The laser module physically interferes with the dust collection attachment at some positions. It took quite a bit of adjustment to get the x-axis to not bind at the far left side. It may take several attempts to get the wiring positioned so it does not bind or interfere with operation. All these have satisfactory solutions so would not “break the deal”.

Have to say it was as easy as advertised. This was my very first CNC and it took may over a year to decide. I’m a bit land locked for space so some of the larger tables didn’t work, also my budget to consider. So my requirements were smaller footprint, but also larger than the desktop models – the 30×30 is perfect for me. I initially wanted to spend around $1000, but then review/options/size pushed it to $6000. That’s when a friend said “Maybe don’t spend $6k on your first CNC”, I’m glad i took his advice. I found the Longmill and what really sold me was the lead screws over belts, ease of installation(videos are great), the support is fantastic, and the price. My biggest hurdle
so far is my education of CAM processing. I’ve used Fusion 360 for a while in the CAD space for 3d prints, but the CAM is new to me. Selecting the correct tool paths, bits, speed/feed rates. I use gSender, had add-ons like auto zero touch plate and dust boot. As for as the Longmill’s performance I’ve done some minor engravings, but nothing as a finish product yet. If I had any wishes for modifications it might be a wingnut or something for the limit switch bracket on the Front Y axis – that was a pain with my lack of dexterity, and not a biggie but the usb controller connection on the opposite side of the connections restricted an under mount of my controller. Having one side with no connections would allow it to seat against a wall/side of my table.

Hi Chris, I bought this machine for my neighbour, stretch, who has put most of it together and built a solid bench for it, but unfortunately when we put the first screw into the front foot, the back foot lifted up off the bench by about 10mm.
This highlighted a slight bow in the bench top, that was preventing the machine from being able to be fixed down without bending the rail.
So he had another crack at building a flatter surface, but he wasn’t happy with his 2nd attempt either. Now I’ve inherited the task, and I’m in the process of cutting out a sturdy flat base on my 2.5m x 1.5m
Australian made multicam cnc router.
If you check back in with me in a couple of weeks I’m sure he will have tried it out by then,
Cheers Joe

The machine and the customer support have all been excellent. I have been running it hard with little issues. Assembly was simple enough with the instructions you provided. Thank you.

So totally impressed with Sienci Labs and the machine I purchase, I recommend this company if one is in the market for a bench top CNC!

Once I got it all set waste the fort I was doing my waste bored my router burnt up, but so far everything else is going good
David Lee (verified owner) –
Very Nice Machine! Followed the instructions and everything went together smoothly. Works very well.
Jurgen S. (verified owner) –
The cnc came faster then expected,
Assembly was easy
Have not done any projects with the router itself,
Have done a few engraving’s with the laser
George M. (verified owner) –
Very well made and easy to setup. The instructions are very clear for assembly. I was up and cutting quite fast. I have a bit of an advantage that I’ve been in the IT world going on 25 years, so using gsender was a breeze.
For someone that does not want a big learning curve, I suggest trying out Easel. It has a simple web browser interface. The driver for the controller works flawlessly. It does not have the depth of features like VCarve, but if you are looking to do mostly simple carving – it will do the trick.
I would also recommend getting the induction sensors. I know it’s not “required” but for the simplicity of being able to click home to send the spindle back to point zero is a time saver.
All in all – great machine (and Canadian made!).

This is my second longmill and I continue to be impressed by not only the machine but the high quality customer service as well, if you are looking for a great quality machine don’t look any further the longmill is for you.
Doug Davidson (verified owner) –
None of the four corner feet were tapped in all four holes, I had to tap them myself like I saw on your video. The Ttracks never got shipped, I called and the nice lady I talked to fixed it very fast. All and all no big deal and I am happy with the machine. Not a new CNC guy, this was an up grade
Terence Chester (verified owner) –
I took a week to slowly built the machine, taking care with every step, and it paid off. The machine seems to work perfectly; I used the levelling program, and have made the samples you provided. I can see no problems so far. I am experimenting with the various software programs, and have decided on Carveco. I’m glad I chose the smaller machine, it fills my small hobby workshop just fine. I am very pleased with the product.
Brendon S. (verified owner) –
Very good quality machine with multiple applications great for the cost!
Mike (verified owner) –
As a new CNC owner, I took a lot of time researching the different brands available within the “Desktop” category and finally chose to invest in the LongMill. With being new to this, I relied heavily on existing reviews and was a bit skeptical, but am glad I made the decision I did.
Unit did take the 5 weeks to deliver and their customer service was very polite when calling to obtain status on the unit. Albeit, 5 weeks is a long time to wait when looking at a new toy and if you are impatient like me, it feels like forever. The one upside to this, it that it provides a very good opportunity to decide on software, download and install it, and start making designs to understand tool paths, cut depths, etc prior to the machine arriving.
When the machine arrived, assembly started and I was super impressed with the packaging and all of the resource materials available to move you from step to step. Machine was assembled within about 5 hours and I was able to test one of my design that day.
Highly recommend that if you are considering a CNC to move forward with the LongMill. The only regret I have is not getting the 48×30.

Other than Z Axis lead screw coming loose and falling through twice and ruining 2 projects everything has been working fine . I keep that lead screw fitting tight to the point of stripping it out and it still fell off twice. Not from motor side but lead screw side
Lynette Hoaglund (verified owner) –
Overall I love this machine. I don’t believe you can find a machine that is comparable at this price point. It done some unexplainable things when I first started running it but now seems to be operating as it should. However, I am still having trouble with getting the Vwheels adjusted and keeping them adjusted? I get them adjusted to where I believe they should be so that I can turn them by hand with a little effort but, after a short run they tighten up to where turning them by hand is impossible and they begin to make a squeaking noise while in operation or they loosen up and you can free wheel them? I’m sure it is something I am doing wrong but I can’t seem to find that sweet spot to where they stay in adjustment. Any advice on resolving this issue would be greatly appreciated.
