PleaseNote: 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 their 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 dimensioned drawings all of the machines, please download our PDF document. If you’d like to see some tables that our community members have built for their own machines, we’ve got a page on it here: Community Table Builds. If you’re looking to properly size a space to put your machine or are making a dedicated table, ensure that you leave enough room for the LongMills control box and any other peripherals that you might be using like a laptop, monitor, keyboard, etc. The control box is roughly 150mm x 280mm, has holes so that it can be easily screwed or mounted to any surface, and has a USB port on its left side which allows you to connect your computer to control the machine.
FAQ
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!

I love my LongMill CNC!! The kit was complete and packaged well. Setup was easy thanks to the detailed video and written instructions. I was creating the same day as setup!! Already putting away funds for my 2nd system! Everyone at Sienci is amazing and responsive. After many hours of research before purchase, I know that I made the best decision with Sienci! And thanks to the incredible CNC network out there for all the support and tips! This is an open, sharing community and it helped me dramatically reduce my learning curve. Thanks, Sienci!!!! TB

I love the machine. It runs very well and was really easy to set up though looks intimidating. The Gsender program is great too, I haven’t dove really deep into it but being able to see my work on a screen helps out a lot. A huge help is the auto zero system with the newer plate that came with the kit. Very happy with the purchase. Customer support was excellent as well when I got stuck at one point.

Just like most things in today’s society, there are lots of choices when it comes cnc machines to choose from. Ultimately the Sienci machine fit my needs, price, and the support associated with it. I appreciate a small business that makes helpful videos and responds to questions, whether it be on Instagram, or the forums.
I am full-time custom acoustic guitar/ukulele builder, and this machine will start replacing a lot of my delicate needs. The quality of everything is great, as well as the instructions to put the machine together. I can’t really say I’ve experienced many issues yet, and the only thing that sometimes doesn’t work is gSender. It is quirky sometimes when it decides to stop in the middle of a cutting job with no reason. Otherwise 9/10 stars!

Did my first project the soap dish holder turned out great. Finished it last night. Started this week but I had a couple hiccups so I stopped ran it through last night and everything worked good so don’t know exactly what happened eager to get started on the next step, I’m not real computer literate but I’m learning as I go

The mechanicals are well built however I had intermittent problems from the start. I thought it was my lack of knowledge but it turned out to be a defective power supply. My machine has now be down for two weeks waiting for a replacement. Due to the intermittent nature of the problem tech support was pretty responsive. I have had my machine for a couple of months but haven’t been able to really put it to use.

I’ve had my Longmill MK2 beginners kit for a few months now, and really enjoy using it.
Not to say I didn’t have a learning curve, because I definitely did.
I gouged wood, broke bits and ran over hold down clamps like I think anyone would with their first machine.
Having an assortment of bits and the vacuum attachment right out of the box was huge and allowed me to actually make a few things, like a tray and a really nice looking v-carve without waiting to get bits. It was great!
About the machine.
Again, right out of the box the machine looked very strong. The beams are huge!
The instructions were excellent, although some of the photos could be better, but overall the assembly was easier than I initially assumed it would be.
After getting to know Carveco and gsender things have improved significantly.
I would give my Longmill a 5 Star review because every claim that is made has been true.
Thanks for living up to your name!

Quality is excellent and value can’t be beat. There are some tweaks that I am learning the hard way – properly tramming the router, tuning the gantry wheels just right, and I had an arduino board die on me suddenly – Sienci supported it 100% and replaced it quickly.

Cnc works great .. good stiffness.. assembly was straight forward and worth the cost savings it offers over other desktop cnc routers on the market and it makes troubleshooting mechanical issues easier as I was very familiar with the construction of the machine.. the one thing I would mention to anyone looking at cnc is get familiar with the software before you receive or build machine. For most people the design aspect of cnc will be the biggest hurdle. After all it’s a 3k paper weight if you can’t program. Program’s like carveco or v carve are user friendly but without a background in cad or blueprint interpretation I could see it as being a learning curve….. but we’ll worth it…. my first project was a clock with some v carving reliefs…. very satisfying

The kit went together as directed. I have not been able to get the probe to work properly. I must be missing something in the set up or use. I have been using the manual method to set the starting point. The learning curve is reasonable with some frustrations and a pile of scrap material but the end results are what I wanted. It has been fun and enjoyable.

I enjoyed putting this together. I really appreciate that I didn’t have to pay the shipping for the MDF that I was able to pick up locally. That kind of logic really boosted my confidence in your company. The written instructions were very clear and the video demonstrations were well done. Between the two, I felt confident I was putting it together correctly.
