This is a modified build C-Beam XLarge. 1000mm C-Beam used for X and Y axis, and the Y Axis moves the X bridge, not the material being worked.

The C-Beam Prefab Untitled is designed as the cartesian compliment to the C-Beam XL. With the exception of requiring a couple more 1000mm C-Beams and lead screws, the build requires a minimum of additional parts. The primary intention of the build is to maximize the cutting envelope while still staying within the sweet spot for C-beam rigidity. This design can easily be modified and allows for further custom structural components to be cut with the initial build platform.

I started this build about 2 weeks after the c-beam hit the store. I purchased a single bundle and ordered a TinyG to run it. where I work I have Hardware, Software and Mechanical engineers and they all got sucked into my project. they want one to do prototyping at the office, once they see mine...

My Experiences building the C-Beam X Large. Maybe you can pick up a few pointers from my ramblings and experiences if you are considering building this machine.

A Modified and augmented Ooznest C-Beam Machine Plate Maker.

I never thought owning a CNC machine was possible until I stumbled upon the Openbuilds site. After viewing numerous builds I was drawn to the Ox by Mark Carew but ultimately decided on a build of similar design, Halloumi by Savvas. It's a C-beam design driven by Nema 23 steppers with Acme lead screws. Like Savvas I will be fabricating temporary plates to get up and running then use the machine to mill the final plates. The material I'm using for the temp plates is solid surface (Avonite).

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.

Building a larger C-BEAM CNC Machine with no previous experience.

I’m making a desktop CNC machine based on the C-Beam platform. It will be driven by Tr8 Lead Screws, and initially made from 12mm birch ply plates.

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

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

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.

1000mm x 1000mm C-Beam XXL CNC with external drivers and high torque Nema 23 motors, 2.2KW Spindle with VFD.

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.

Machine based on Sphinx 55 built with linear rails.

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.

Per the special notes its a variant of the C-Beam, Machine.... I have noticed that alot of people build a CNC router to cut parts for other larger CNC machines.. eg Delta Printers etc....plus this will enable me to cut parts for model RC plans UAV's etc...

This build is inspired by the Lulzbot Taz printers and makes use of the new OpenBuilds C-Beam

This is a 1-Axis CNC Glass Grinder. It uses a hobby grinder to miter a precise angle on the edge of a piece of glass.

Concept for a Prusa i3 made from Cbeam Extrusion. X & Y using GT2 Belts, Z using Acme Screws Goal is to build a simple. and very Solid Printer Single Z Motor to keep the Z Screws in Sync. (Might require Geared Nema 17) 12" x 12" x 12" Build volume Nema 17's

SLA resin printer based on a gen3/4 iPad Retina display. The design intent is to create a printer with the highest resolution possible with a lower cost of entry compared to DLP projector based SLA printers.

A C-Beam router made almost entirely of standard parts. Electronics include an xPro v2 board and NEMA 23 motors. Cuts are made with a small 300W DC spindle. A pressure foot is used to minimize the need for workholding.

The UltiBots CB3030 CNC uses C-Beam, V-Slot and an extruded aluminum T-Slot work table. This allows 6mm T-Nuts, step clamps and blocks to secure materials to the work surface. The all metal design makes the use of a mister possible.

The build is based on a 500mm C-Beam and the SeeMeCNC FlexVat. The C-Beam is both the linear motion and a structural element of the design. The frame that holds the 45 degree first surface mirror and the build vat can slide up and down the C-Beam to accommodate projectors with lenses at different elevations.

This is a CNC Line Boring Machine for our cabinet shop. It drills the holes every 32 mm for the adjustable shelf pins in the cabinet side pieces. I chose this option over purchasing a multi-head boring machine that requires 11 drill bits - Left & Right hand twist - that also requires a lot of strength to plunge that many drill bits into the wood to be drilled.

Work in progress.. but nearing completion :)

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.

classic router with a ab table

This easy to build actuator is configured to have not only strength, but accuracy! This low profile option offers endless possibilities, and we cant wait to see how this actuator is implemented in your build ideas!

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.

A short description of the dust shoe I made for my machine.

Based on the popular C-beam / V-wheel design, with the largest available work area, relative to machine size. Screw driven with anti-backlash, integrated drag chains, Carbon fibre gantry plates, Openbuilds BlackBox Controller (USB), Transformer & kill switches, with internal wiring, limit switches & Nema 23 motors.

The idea is to make a simple effective ventilator, studying the concept of using a simple push process with and actuator.

A Sphinx build to inspire and encourage all those who want to get started with cnc to check out Opensbuilds line of machine bundles and hardware.

This modified C-Beam, is a compact, powerful and affordable desktop CNC.

A compact, strong machine with very high Z clearance, yet can still mill aluminium easily.

A design in progress, to 3D carve two-part Aluminium injection moulds for Soft Plastic Lures and Lead Jigs, so I can prototype some of the concepts rattling around in my head. All Openbuilds parts where possible, 1000x500mm footprint, 0.8kw Water-cooled Spindle?, High Torque Stepper?,Smoothieboard?, I still have no idea. As a newbie to the CNC world, any wisdom would be welcome to take this from just a idea into reality so I can start playing with all this awesome stuff. Thanks in advance

Here are a few helpful C-Beam actuator ideas that will help you get a start on your builds

Been using the Ox now since 2015, so decided I should move on to C-Beam :-)

C-Beam XL build using TinyG V8.

Rigid variant of the C-Beam sphinx platform

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.

I'm building a machine specifically for doing 4th axis work on woodwind instruments.

I want build a frame that is as sturdy as possibility while at the same time keeping it as compact as possible. working area will be approx 1200mm x 600mm

So we have new plates, stronger motors, belt drive reduction, but what should we do with them? In this article you might find the answer you were looking for as we took an “old” C-Beam machine and started to upgrade the X/Z body and added more torque and precision to the Z-axis.

This is my first CNC router build. I want to gain basic CNC building experience so I can go on to build other items such as a frosting or pancake printer.

The reason for building this CNC is to help me in my guitar building hobby. (telecasters)

The STEAM Crane 3d printer uses the new C-Beam linear rail. It is being developed for an after school / summer camp program for kids. All of the electronics are housed in the base and the wiring is routed down the channels of the c-beam. This is done to contain as much of the loose wiring as possible, hopefully keeping it safer for kids.

The new C-Beam kit expanded to 1000mm . extra support built in for the extents of the travel.

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 Router using 1500mm lengths, 48x48" build area, and rack and pinion movement.

One meter square. Short and stout.... reminds me of a Sumo Wrestler. A temporary and adjustable configuration I have devised to cut my own plates. I have kicked around ideas for about a year and the C-Beam extrusion has made this attempt to realize my ideas irresistible. This is just one step towards bigger and better things!

feel kind of bad calling this a build because of pretty much everything is off the shelf parts. I'm writing my own sketch right now for the motion but there is a version or 2 floating around on the net based of this design. I will post my code once it's done.

C-Beam build using the small C-Beam gantry plates only.

Short description of my assembly and use of the C-Beam bundle from the Open Builds Part Store.

The Mule is a 3-axis CNC inspired by the OX CNC by Mark Carew. This machine borrows the OX's sturdy frame and upgrades the X and Y linear actuators through the use of three 500mm lead screws (as opposed to the belt system of the OX). The result is an inexpensive, sturdy, and powerful design built for cutting tough materials such as aluminum.

This unit is made with openbuild v-rail and c-beam. using direct drive with lead screws. Nema23 motors

First venture into cnc machining I decided on the C-Beam .

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...

I am in the design phase of my CNC. I would like to thank everyone who has placed resources on the site. I am using it to the up most! I will update as I continue the design and share my progress.

Here is the consolidation of my woodworking shop, a CNC Router!

Cheap Ballscrew Ox CNC Router.

C-Beam basic package doubled in size.

This CNC utilizes the C-BEAM extruded aluminum for the "X", "Y", and "Z" axis. The gantry will move similar to the OX along with the "Z" except I am incorporating the C-BEAM instead of the 20x60 V-RAIL. To make the system as strong as possible I am using two C-BEAM rails back to back. The "Y" axis will encompass two sets of roller on both side of the C-BEAM extruded rails for added strength. All of the plates for this were created using the C-BEAM machine I completed several month ago.

C-Beam inspired CnC Router (1000x750) Approx 90mm of Z travel

Machined Aluminum MagBall Carriages

3.8 W laser add-on for C-Beam machine. Can easily be swapped with the router.

My first build was with the basic C-Beam Build. I soon found the z clearance a little constricting So I added 2 500 mm actuators to support the x axis rail . I also left off the front and back y axis support rails for easy cleaning. I mounted the base of the machine to 1/2" mdf with 10/32 screws and blind nuts.

C-Beam Machine upgrade using linear rails to increase machining size by 2.5 times and increase rigidity

This is a variant of a typical OX (Mark Carew inspiration) router using C-Beams/8mm Acme rods to drive all three axis. I went with a 1000mm x 1000mm frame size. Useable space is 28" (711mm) X 26" (660mm) with a Z axis work travel of approx. 3.25" (82.5mm). A TinyG is used as a controller along with Fusion 360/Chilipper as the software for generating and running gcode files.

This is a C-Beam build, fairly heavy duty, and 750mm x 750mm. Should be a good, sturdy machine that's relatively easy to assemble.

Larger format FDM printer using C-Beam linear stages

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.

Pretty happy with the build, had some difficulty with the software loading up the settings due to me using the wrong com.

I am a newbie and this is my first build. After hours and hours of research I decided on the C-Beam. I will be changing one or two things but I will basically be building this as per Mark's video.

Overview of my experience building the C-Beam Machine XL from OpenBuilds, along with updates as I move along and get it going. My application is for creating plates needed for lab functions, 19 rack bay covers, and whatever else arises.

Another C-Beam Sphinx but a little larger,

The C-Beam Evolution is an evolving machine. The MkII is inspired by Kyo's C-Beam Spinx but currently uses my own design of plates made of 8mm acrylic (X-axis ends) and 6mm polycarbonate (Y axis ends). The plates were made on the MkI but I hope to be able to make 6mm aluminium plates on the MkII for the MkIII.

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.

Build log for my first CNC machine, a C-Beam Plate Maker

This built is to convert an existing 500x500 C-Beam Machine into 1000x1000. Inspired by several builds including C-Beam Machine : (http://www.openbuilds.com/builds/c-beam%E2%84%A2-machine-plate-maker.2020/) and Gino's build : (http://www.openbuilds.com/builds/c-beam-gtc.3250/)

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

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