I built this cnc using 2 z axis actuators thinking it would minimize deflection and it seems to be very sturdy. I used 2 1500mm c channels for my x axis, 1 1500mm c channel for my y axis, nema 23 stepper motors, dm556 drivers, 2 24v power supplies, smc5-5-n-n controller, 9mm wide belts, and the Hitachi m12vc router. So far it's working very well with a few hiccups. Programming the controller was a learning experience but I'm very happy with it.

A CNC machine with an expansive 30x30" work area, supporing a router, laser, simple plotting and work monitoring camera. Control includes a tethered control box, game controller style jog control, and relay controlled AC outlets for all appliances. Accessories include a 3D printed dust shoe, a complete spoilboard and hold down system, an XYZ touch probe and multiple vacuum retention boards to support full profile routing.

Modified C-beam Machine. Taller (30 cm) C-beam uprights in gantry, and longer 750 mm frame in Y direction. XL gantry plate on X (and Z?). Y will have additional 700 mm SBR16 rails as extra support and slightly raised bed to fit above stepper motor. Approx. machinable area of 370 x 370 mm.

Upgraded Sphinx Cbeam using 3/8 aluminum plates and linear rails / ballscrews

My Machine is based on the OX CNC designed by Mark Carew as well as the ooznest kit, and it incorporates a bunch of my own details and revisions to increase performance and robustness. It has become way more beastly than I originally planned!

A no-nonsense CNC mini mill to get the job done.

Small Mill type CNC machine, using C-Beams and V-Slot rail, bundle packs as a starter point. I needed a smallish desktop machine to fit a pretty narrow use case for my business, but the machine itself has larger applications to the OB community. Currently I will run the Dewalt 611 router on the Z axis, but have plans to add in a brushless RC style motor. So this design does have room to go either way easily.

The TACIT RONIN CNC is a fully enclosed C-Beam platform intended for flood coolant cutting of Carbon Fiber and G10 composites.

A small system with a big bite. Design achieves a good balance between machine size vs. build area, rigidity and ease of construction all while keeping build cost as low as possible.

I got lucky enough to purchase aluminum extrusions and linear motion components (and nuts/bolts/etc) at scrap metal prices when a bunch of industrial automation equipment was decommissioned. The only problem is that the aluminum extrusions are not metric sizes... they are the 1.5"x3" 80/20 series. It has presented a few challenges but nothing too bad.

I love the C-Beam XL concept, this build is my custom version with the goal of increasing rigidity for metal milling.

Yet another build of an improved C-Beam Machine, improving stiffness, size, versatility, and strength without increasing costs much.

Upgrade your Minimill with an off-set Z Axis Motor

This is my first public build. Please be kind. We upgraded our C-Beam to the C-Cbeam X-Large. I want to give special thanks to Moag and the OpenBuilds team for making this happen.

This is my first foray into CNC machines, after much review I decided on the C-Beam machine as it seemed easy to work with and will enabled me to build more and larger machines as I gain knowledge. I am planning on building the machine largely unmodified from the reference design. I will be building the machine an axis at a time as I need to spread out costs over time.

This is the story of my progression from the JGRO cnc router design to using the OpenBuild system. In the process I think I have learned some things about cnc routers and the accuracy required to make a good build.

With the focus always on larger builds I wanted to focus on a desktop PCB milling machine that fulfills the average users desktop needs at an entry level cost. Design considerations will allow expandable capabilities to include 3D printing and any other functions a small form Cartesian robot can perform. The current iteration has a desktop footprint of approximately 15.5" X 14.5".

This is my first CNC router build, so I started with the OpenBuilds C-Beam Machine XLarge mechanical bundle, including four high torque stepper motors. I took my time with the mechanical build, sought and found some great help for my control system, and designed and built a custom cabinet to house everything.

I built a CNC Router using 3/4 MDF, 1/8 aluminum angle for bearing races and various other odds and ends. I learned a lot about how not to build a CNC router. I found Openbuilds.com and decided to build a C-Beam for my first build. The long term idea is to use this machine to build custom plates for and OX type machine and a 3d printer.

build is in process the machine went together perfectly no issues at all but the software is another issue I have been trying to get the thing dialed in it is driving me nuts I'm still in the process will update if I ever get it figured out

Low cost, apple crate framed CNC.

This will be a chronicle. It's my first CNC build so, I will be making many changes as I learn from my mistakes. I will pass on any tips or tricks i learn along the way. This build is an OX Hybrid. I decided to use the open rail with the V wheels and not to go with the V Slot. (I'll let you know how it works out.)

Stable solid, hope can cooperate with coolant in the future.

This machine is fantastic. Teamed up with Fusion 360, Inkscape, and GrblPanel, I'm well on my way towards making at least one Christmas gift this year. I had some frustrating times during the build, mainly with getting everything to go together square, but overall it was fun. I can see that I'm going to need to be a bit creative in order to max out the work area for this machine so that I can produce the product I bought it for, but it will be able to do so much more for me as well.

My very first attempt at a CNC build. Based on the OpenBuilds C-Beam Machine, small tweaks will be made to tailor it for my goals: machining G10, aluminum & some carbon fiber for use with multirotor and motorcycle parts. I am looking forward to the day when I am comfortable enough to bring the ideas in my head to the tip of the end mill in a smooth fashion...

C-Beam Machine for PCB milling

Used Laguna Swift 4X4 CNC mill with Water-cooled Spindle and RichAuto serial pendant retrofitted with OpenBuilds/Blackbox/Interface

Hello all, wanted to share my custom build that I planed to do. My idea was to drill foam blocks to make molds for my projects. The CNC will be 1500-1500mm with a higher Z-Axis. So I redesigned the Gantry Plates that will be cut out at some other place. I hope you can share your opinion on my project.

My first openbuilds submission, plain old c-beam machine. Seems like I've spent more time fighting the forum here redirecting in circles than actually building the machine. I'll try to add more pics if I ever find a path out of this corn maze...

My very first CNC Router build. It's completely scratch built.

This is my interpretation of the OB Minimill, what I've changed so far, and what may continue to change as my requirements change.

First time CNC user having a good time with a MiniMill

I used the cad designs for the c beam to find a solution to my initial sourcing problem. I figured that I could use 2x 20x20 and 1x 20x80 Profil to create a c beam actuator. I sourced all of the profiles from a local machin builder and t-nuts and screws in my local hardware store. Some parts are currently in 3d printed pla for testing reasons.

Z-Axis upgrade with linear rails, SFU1204 Ball Screw and full aluminium construction.

I put this together to cut aluminum. Chips get everywhere! Cover your lead screws. Put the mill inside an enclosure. DON'T mount electronics (especially the power supply) inside the enclosure, chips will get into it and short it out. Remove the manual jog wheels, they contribute to chatter (something about having a mass on the end of the lead screw causes vibration). I cut at 14000 RPM, 0.05 inch width of cut, 0.05 inch depth of cut, 30 inches per minute and just barely avoid chatter.

Home Made CNC Router from Scrape

C-Beam Plate cutter with Raspberry Pi V3, Arduino Mega2560 and Camera. Remote login & operation via SSH with cnc.js server, mjpg server on the Pi.

So for a summary its a great kit that was easy to build, could not be more happy.

This is my first attempt at building a spindle based CNC machine. The intention is to mill PCB boards and mill delrin blocks. The device was built with an Emergency Stop that actually cuts power to the spindle and motors. This is a post build write-up and consists of finished photo compilation and CAD renderings.

This is a slightly-modified OpenBuilds minimill with some more Y travel and a v-slot table.

This machine is controlled by a Mach3 BOB. I USED Nema 34 stepper motors and a 3kw, water cooled spindle. I’m in the process of adding a vacuum table with 4 zones. I have an X-carve so I use Easel to create G-code for the large machine. I’m currently looking for a way to stabilize the Y-axis. It wiggles a little, so I want to add another linear rail high on both sides.

This is a design for a desktop CNC machine. It may be a router or laser. I am undecided as to the final design.

Contained within are links to our OpenBuilds sponsored C-beam Machine live build taking place at MRRF 2018 (Midwest Reprap Festival) on March 24 and 25, 2018. There will also be some build images and a few 3D printed STL items that were added.

Reusing parts to build a CNC - planning stage

Fixed Gantry CNC with good accuracy and rigidity but for a higher price than the usual CNC's on the site.

I ordered the OpenBuilds MiniMill from the OpenBuilds Parts Store http://openbuildspartstore.com/ They were out of Motors and Electronics when I ordered so I had to source these items elsewhere. But it turned out well doing it this way.

Minimill bundle, but with an extended X Axis

This is my first build and I've been waiting to do this for a very long time.

The new MiniMill from Mark and Sonny is a great little machine.

This will be a CNC milling machine. My goal is to make this mill for the minimum cost I can while not sacrificing quality. In hope of staring an educational YouTube channel on CNC milling and 3D Printing. Along with when to use both.

Currently i am reworking the frame still with current available parts just going to buy material to make the y and the z axis from openbuilds. The x axis is now going to be mobile similar to a 3d printer style.

This is a C-Beam based router with V-rails used for the bed, a Sherline spindle with Jacobs chuck, closed loop stepper motors on every axis and an offline 4-axis CNC controller. A U-channel was created to guide the drag chain on the X-axis.

My first ever build. Straight C-beam with tinyg controller a few do-dads and some make do choices. Non-metric length lead screws to save long lead time. Jog knobs to cover the extra length and also practical. My old Bosch Colt never had it so good. Build out work remains, wire dressing, drag chain, vacuum, permanent base, etc.

A modified C-Beam Build with a few Addons

I'm new to this whole process, so this is a build by a newbie for newbies.

The parts are now very reasonable.
