You did it! You just purchased A CNC. If this is your second (or 3rd or 4th :P ) CNC than you know what your getting into! If this is your very first step into the CNC world then you're probably feeling excited and a bit nervous! I remember when I got my first CNC. That feeling of excitement when UPS pulls up to the house and drops it off. Taking that first picture of the unboxing for Instagram. Painstakingly going through the instructions making sure I assemble it just right. Then, taking a step back, looking at what I just built, and thinking "Ok, how do I make this thing work?"
In this post, i'll be referring to the Onefinity CNC, as this is the current CNC I have, but this will be helpful for most every CNC on the market.
Ah, a proper spindle. If you've been doing your research on CNC machines you've inevitable seen many posts about getting a spindle. Since I'm one of the few with a machine, I'm obviously getting tons of questions about it. And the 'can this run a spindle?' was one of the top requests. So, without ever using one, let alone ever seeing one in person with my eyes, I made a leap of faith and purchased one from amazon. I've created a video all about that HERE (Link to come once I actually edit the video). I'll sum up the video by saying this: It is super quiet and it is not worth the hassle for 95% of you buying the machine. If you are brand new to CNCs, stop right here and skip to the next section. A spindle is not for you. If you are more 'seasoned', a spindle may be for you. I've realized why very few hobby cnc machines officially support it. You have to wire EVERYTHING yourself. And by that I mean, it literally comes with no wires. Wiring 2 and 3 phase stuff that could potentially KILL you is probably not something they want to promote...and only a finite amount of people will actually use one, so it's not worth the liability, support, and $$ to promote one. That being said, it will be really hard to go back to the ear deafening sound of a router now that I've run a spindle.
A router or spindle are great at spinning around but they wont cut anything without a bit inside them. There are countless options in this, each with their own specific purpose. I've already written up a pretty lengthy blog post previously on my preferred bits and that applies to the Onefinity. You can check that out by clicking the button below.
Collets. A Collet is an adapter to hold different sized bits. Every bit has a cutting diameter and a shaft diameter. The Makita router (and most routers) comes with a 1/4 collet. This means that you'll only be able to use 1/4 shanks (the smooth shaft part that goes into the router). Some smaller bits (like a 1/16 or 1/32) only have 1/8 shanks and will not work in the standard collet. You'll need to purchase a 1/8 collet. A great place to buy very good collets is Elaire Corp. I linked a button to their Makita selection below.
Since the default configuration of the Onefinity CNC is open on the bottom, once you attach it to the table you'll want to provide a sacrificial wasteboard as a carving surface and a place to hold down your material. I'm kinda biased here...but I've designed one that most people refer to as the "Myers Wasteboard" (or mEyers if you can't spell my name right). I think its the best one you can get, but i'll leave that up to you. All you'll need is a piece of MDF and your machine will do the rest of the work. The file is specifically designed for the Shapeoko 3 but since it has very similar cutting sizes, it will work perfectly for the Onefinity CNC as well. There's plenty of info about this out there so I'll link the relevant stuff below:
3: Cam, fence, and L clamps. To go along with my wasteboard I designed a bunch of different clamps. I've created a blog post and YouTube video to explain them. They work really well and leave no marks on your material. Also, since they are low profile and made from mdf, you don't have to worry a about running into them with a bit and breaking the bit or the clamp. The video and files were designed for the Shapeoko 3, but will perfectly apply to the Onefinity (and any other CNC) just as well.
5: CAD (Design Software).
I have made a bunch of videos showing how to use Carbide Create (free). I'll be doing more on other software in the future. Check out my Carbide Create series below.
6: A Computer
You'll need a computer for one of two reasons (or both in some cases) for CNC machines. The first is programing the CAD (design) software. The second is actually sending the gcode created from that CAD program to the CNC machine (by using CAM software (motion control)). For most hobby cnc machines you'll need to be teathered to the cnc via a usb cable during the whole cut. For the Onefinity CNC machine, you do not thanks to its controller with built in cam software. For designing CAD, you'll want something a bit more powerful (especially if your designing 3d files and not just 2d). For running CAM, usually a inexpensive computer will do just fine as its just streaming a small set of data over usb. I'll link my two favorite computers I personally use. Click the pictures to purchase.
7: USB Stick
8: Joystick (Another Form Of Jogging)
There are many ways to jog (move) a cnc machine. Most included using the mouse and clicking on a computer screen. Some machines have the ability to connect a game pad to enable jogging. This is a nice feature as you can stand directly in front of the machine and watch it move rather then watching a screen. The Onefinity allows the use of game pads. I linked two below that I've personally used and tested (clcick the pictures to purchase). The blue one is a wired one, the silver one is wireless (I personally recommend going wireless!).
Once you get cutting it's not really ideal to stand in-front of the machine for hours (although its NEVER recommend to not monitor the cutting process, you never know what could happen!) Fortunately we live in an always connected digital age. There are two ways you can remotely monitor the cut. One way that is specific only to the Onefinity is plugging in a usb webcam to the controller. If you do this, a box will pop up on the screen (that you can access from any device on the network) with a live video feed from that webcam. It's a really cool feature. I used two webcams (one a 720p and one a 1080p) and they've both worked perfectly. I'll link them below, click on the pictures to purchase.
The unfortunate side of cutting on a CNC machine is dust. Lots and lots of dust. Some material is worse than others. MDF is particularly bad for your lungs, and cutting it creates A LOT of dust. The Onefinity CNC supports (and all preorders get) the Suck It Dust Boot. This allows dust collection right at the point of cutting. Now you'll need a vacuum to suck up the dust. Unfortunately most vacuums are very loud. Add that to the fact that the routers are really loud and it's especially uncomfortable for your ears. I've had a shop vac in the past. They work well but are over 80 decibels. While researching other vacuum alternatives, I found Fein. They are German made, have the quality of Festool vacuums and are much cheaper. The best part is that its less than 50 decibels while running. It's one of the quietest vacs on the market and is still going strong 3 years later!
11: PPE (Safety Equipment)
12: Touch probe
The basic principle of this type of probe is that the continuity of an electric circuit is broken when the probe touches a feature in the XY plane at a given Z position or touches a surface in the Z direction at a given X & Y. This lets the machine know where the starting point to cut on the material is. While a touch probe is not a necessity, it makes finding zeros more automated. Most any touch probe will work with the Onefinity. They will be selling their own branded probe.
Finally, you'll need something to cut. The materials you can cut on a CNC would be wood, acrylic, plastic, chipboard, aluminum, brass, linoleum, brick, hdpe, pvc, and many more.
Hopefully this post was helpful in what to expect when you purchase a new CNC. If you have any questions, feel free to write them in the comments. If you can think of anything to add, send me a message and I'll edit this post.
I'm happy to say I have the Onefinity CNC in my shop! Made by the people behind Suck It dust boot, it's an all axis ball screw machine in a modular design that only took me less than 15 minutes to breakdown in my shop and move, set up and cut in my friends shop. Remember when you put together the Carbide 3D Shapeoko and it took a full day...or worse, the Inventables X-Carve and it took 5 FULL DAYS! From unboxing to cutting you'll be done in less than an hour (it took me 15 minutes). Moving the other machines takes two people. You can move and set up this one by yourself. The beauty of this machine is when you want to move it, you can move one rail at a time. You don't need a truck or large suv to move the Onefinity. I took it over to my friends shop in my wifes car.
I'm a huge tech nerd so anytime you put wifi in something I'm all in. The controller is something special. It's basically a computer inside. Gone are the days where I have to hook up a usb cord from my computer to the controller on my cnc machine and tie it up until the piece is finish, or worry that my computer or usb might go to sleep in the middle of the cut and I lose hours of work. Also, who want's to take their expensive laptop in the shop to get dusty or drop it? Once you have your design done and you save the gcode file, you simply put it on a usb stick or log into the controller via your network (if you choose to do this, wifi/internet is NOT a requirement for it to run) and transfer the file. Simply zero your work piece via the touch screen and click start. If you've used cncjs or ugs you'll love the feature that shows the simulation of tool paths while it's cutting. The Onefinity has that feature built in as well. You can monitor your cut and it's movements while it's cutting. That's really handy when you're trying to avoid cutting into your clamps.
The awesome part of optionally connecting it to your network is the ability to use your phone (or tablet) to control the machine! I always have my phone on me and love the fact I can control it from wherever I am. If you hook up a usb webcam (any of the shelf usb webcam will work) a screen will show on the controller page of the camera's view. You can watch your machine cut directly from the screen! This is perfect for those long jobs when you want to head back in the house to catch an episode of Tiger King on Netflix but still want to monitor your cnc for any 'mishaps' that may happen. You basically created your own cnc baby monitor.
The controller also has hook ups for VFD (for when you want to graduate from a trim router to a spindle) built right in. I have a usb gamepad controller hooked into mine for when I want to jog the machine while not directly in front of a screen. Almost too many options for jogging and control.
There's a larger z height than I'm used to on this machine which allows me to cut thicker stock. And if I raise up the rails I can put as thick of a stock as I'd like underneath. I could even potentially place it on top of a completed table and carve in a design. That's a huge up sell if your created custom furniture.
The Linear bearings are sealed so there's no need to worry about dust entering them. I constantly had to clean my v wheels and the rails that they road on to keep them smooth before. Ever have a belt snap in the middle of a paid job or a rubber v wheel break in half? You either have to start all over or wait to get a new belt or v wheel from amazon. With ball screws that problem goes away. As for maintenance, after a certain amount of hours on the machine, simply apply oil in the ball screw hole and that's it. I've seen way to many complain about making my wasteboard and it not drilling the holes all the way through. 99% of the time the problem was the stepper motors skipping steps because the belt was loose.
Belt stretch is real. When you get your new machine or new belt you account and adjust for the belt. After time rubber will loose its elasticity and stretch. This will cause your circle to come out ovals. Ball screws eliminate that problem too.
Since the controller has built in cam, you'll just need to provide your own CAD program that can create files. I've tried Carbide Create, Easel, Fusion 360, Meshcam, Solidworks and Vetric Aspire (Vetric is my go to) so far. All work just fine. I intend to try out Carveco soon. It's highly likely that those will cover 90% of the users out there. Basically, If your CAD program creates gcode, you'll more than likely be able to run it one the Onefinity.
The Onefinity uses the proven nema 23 motors just like the xcarve and shapeoko 3 does.
Rapid movements are increased up to 700 inches/minute on x and y and 400 on the z. Bottom line, it's pretty fast for a hobby CNC. Faster than what I'm used to.
I've been using the machine for a couple of months now and I've had zero issues thus far with rigidity. The rails have been doing a great job keeping things rigid. I'm cutting at faster IPM's than I have thus far. I could basically use the rails as a pull up bar and there wouldn't be flex.
Overall, I think the Onefinity is a great addition to the hobby / desktop cnc scene. It offers the higher priced machine features that more expensive machines carry at an affordable price (which I EXPECT to be priced in the same ball park with xcarve and shapeoko. We will find out for certain in May 2020).

The following are some YouTube Videos of the Onefinity CNC machine.
You guys know me for my work with the Shapeoko 3. It's been a good machine but with some caveats. Belt stretch and breaking, Z movement loosing steps, very heavy to move by yourself, and needing a computer to be constantly tethered to use it.
In comes the Onefinity. Created by the people who make the Suck It dust boot, this machines solves all the major faults of the Shapeoko and Xcarve. X, Y, and Z Axis use ball screws standard. Linear Bearings on all axis, no belts anywhere to be found. The controller is so powerful that it runs its own built in software so no computer needs to be connected to it to send or run files. Finally, no computer is needed in the dusty shop.
I'm one of the first 'influencers' to receive this beast so make sure to be following me on Instagram, Facebook, and YouTube. I'll be sure to post lots of videos about the machine and its capabilities. Check out their announcement video below.

Changing brushes on DeWalt DPW 611 compact router
When your router won’t turn on, nine times out of ten, it’s because your brushes need changing! Here’s how to fix this problem in ten easy steps. Although this tutorial is for the Dewalt, it will also apply to the Bosch, Ridgid, and Makita routers as well. Since this is a widely used router for the Shapeoko 3 and Inventables XCarve CNC desktop routers, it's always good to have a few extra brushes on hand.
What you’ll need:
T-20 torx driver(preferred) or flathead screwdriver & some sort of pointy tool or hook for spring
