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.

This is an automatic bartender- a BarBot, designed to be made with off-the-shelf OpenBuilds, V-slot and low-cost 3D printer parts.

I really like the 4th axis I purchased a few years back, but when I went looking for it again the suppliers who once carried it no longer do. Anyone know who makes it? Center hole receives collets. I own a ShopSmith so I am using a 5/8th rod and can mount it's chucks onto this machine. Also I like the use of the skateboard wheels, they are adjustable and one could use more sets over a longer axis. The Sherline z-axis is not my first choice, I just had a spare.

Cut Area: 825 x 1340. Max Cutting depth: 2 inches. Arduino based control with Nema 23 and Nema 17 drive. 8mm leadscrew and 2GT belt drive. 400W 48V quite cut spindle.

OTiS (Off The Shelf) is 500mm cartesian CNC that can be built with all off the shelf parts from OpenBuildsStore. It features C-Beam actuators and a V-Slot frame.

OKMI 3d Printer based on CoreXY

This will be my first build ever! Looking forward to it , just gotta finish the new workshop first then I'm on it!

D-Bot with a Replicate controller.

I wanted a machine that could easily switch between 3D Printing and Laser Engraving

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 calculator work inside with a spezail count format - Fraction as Mantisse + Dezimal exponent .. in summ 9 Byte.

I wanted to try a different way of operating the Z Axis so I setup a tower using 40x40. In the end it worked excellently and can easily print 60mm/s with 150mm/s travels. The coreXY is a very cool kinematic, and you can get some pretty great speed and accuracy. The main issue is the fact your Steps/mm are doubled, so the lower end motors don't like it at high speeds.

Fast, Large build area, CoreXY design

To begin the "Build" I have ordered a few parts from OpenBuilds to get started. They are arriving today; according to "tracking". I cant wait! Praise Jesus! This 85 yr old man is getting a "New " life. Hallelujah and amen. Because I am building this on an existing machine, I have to be careful; so I will order some parts then see what I don't need (such as a base); along with parts that I may need to adapt it to the machine. It should be fun! "Caint wait!"

Just now in the planning phase of my build. Waiting for some parts to come in to see what I am going to build off of. Print area going to be close to 300x300x350. Trying to decide if I want it enclosed. I do want to print ABS... so probably so.

This is a small CNC mill/router specifically for manufacture PCBs. This is based on the corexy gantry setup. The plan is to have a small, light self-contained machine that can be used and easily but away when it's job is done.

CoreXY based CNC Laser machine.

CoreXZ implementation on 3d printer using Openbuild and RobotDigg parts.

A blend of modular aluminum and steel bracketry built to yield fine cuts in hardwood and aluminum. An open table with a shiftable pin-fixture concept will allow the operator to shift longer than Y-travel work-pieces, such as doors, along the Y-axis of the table. This machine has a 44" (X) by 24" (Y) by 8" (Z) travel with water cooled VFD spindle motor, t-slot ext work table, cable carriers, side guards n dual y drives. Total weight (w/base-stand) is about 600lbs.

The QuorXZ doesn't magically appear. It's gestation takes time, careful attention, and requires many parts. However, when it is ready, a magical, mechanical instrument is born....(and when you finally say its name, it sounds a little bit like "corks").

First CoreXY. Simple Square build, hopes for faster movements.

My first construction after many years buys ready devices.

A Large CoreXY build that can just barely get in through a doorway, aiming for under $1000. Build Volume approximately 18in x 24in x 26in.

The whole system is powered by 12V / DC power. Process it into Pellets or Granules to use it with your 3D Printer or Filament Extruder. Our self-developed steppermotor Controls allows you to optimally adjust Feedrate for your Situation. Forward, Backward and Stop is integrated for easy operation. The Speed can be continuously regulated via rotary switch.

This is an inexpensive build, large volume 2225 cubic inch, CORE XY 3D printer providing decent speed with precise and repeatable precision with expandable features.

CoreXY build

A cartesian build with a build dimension of 200x200x750mm. I will be using a dual extruder, heated build plate, and a screw drive for the z axis.

This SphereBot is based on the EggBot which is an open-source art robot (drawbot) that can draw on spherical or egg-shaped objects.

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.

It all started after my prusa i3 build inspired me to experiment with resin 3D printers because I want to learn if they are worth it and if I can design my own printer.

Based on the work of Carl Feniak and his C-Bot. A robust Core XY style 3D printer that has a clean parallel belt implementation and whose dimensions are adaptable to meet builder's needs. The use of open builds V-slot and other open hardware make customization easy. Utilizing a 300x300 build plate this derivation utilizes three lead screws, synced to a single motor via gt2 belt

Work in progress large volume CoreXY printer

I will be attending the 2017 Midwest RepRap Festival (MRRF) with a small team of printer enthusiasts with a goal to fully assemble a Core-XY D-bot onsite during the event. This is our first attempt at building a D-bot and we will be learning things as we go. Our hope is to have the entire machine assembled, wired, and functional (at least to the setup and testing phase) before the end of the show. Please attend and watch us in person or visit our feed channel during/after the event.

A humble first time attempt at building a 3d printer from scratch

I need a large build plate without spending 10-20k for a "store" built printer.

This is a work in progress

DIY Pano Head

This is going to be a more or less detailed how to build BetterBot. Pictures and more (decent) text are to be added.

This 1500mm tall Delta is a work in progress. The triangle corners are water jetted from 1" 6061 Aluminum, and are welded to 1" square tubing. The 1500mm OpenBuilds 20x20 V-Slot extrusions are held into the corner brackets by two stainless steel set screws per bracket. This printer will need to be reinforced with wall brackets due to the combination of height/materials.

We wanted to create a rapid prototyping machine with excellent 3D printing, laser cutting and engraving, and light CNC router work capabilities.

This is my journey on building a rack and pinion Ox variant called the F-117 CNC.

Dual X-Carriage CoreXY. Not impossible, but probably the only one. Use the link to Thingiverse "Hlidskjalf" for parts and downloads.

PPR = Portable Plasma/Router. A ~30x30"work area with leadscrews. Work surface is below support members. Can be placed ONTO cutting surface.

This is my first major project.

This Project is meant to teach introductory robotics and arduino styled micro-controllers to HS and MS students.

This is my own modified version of the D-Bot printer. I wanted to spec this printer to be able to print exotic materials at high accuracy with little to no compromises and maximum reliability.

For the x and y Axis you set the zero point with a limit switch, but how can you get the zero position for the z Axis? You have different thickness of material to mill and when you change the tool, you have also a other z Axis positon. With the Sensor, you can define the zero position of the piece automaticly.

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.

Corexy, with possible head change (3d, cnc, laser)

H-Bot mechanics 3D printer. Build volume - 300x300x300mm dimensions: 560x500x500mm

A CoreXY D-Bot 3d printer using gantries as wheel-carriages.

I have based this build on the OX build so I will not be going into too much detail of specefic assembly modules as they asre so well covered by Mark Carew already, but will go through the complete build on video. I will be addig additional tutorials on steppers and the other electronic parts as needed though as this project is sponsored by RS Components in the form of most of the Electronics and this is also the key focus of my YouTube channel www.youtube.com/c/thebreadboardca.

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.

Designed from the ground up as a low cost, highly scalable delta printer. This printer has been built as small as carry on luggage size, up to an 18in wide print surface and is capable of larger. Approximate cost is low to mid $500 range start to finish, including electronics for a basic model.

My version a Cartesian style 3d printer, an attempt to eliminate frame vibration and movement and to use up materials left over from other projects.

A Rostock style delta bot with the parts which are typically 3D printed made from medium density fiberboard (MDF). It uses a home made hot end.

Just an idea right now but will attempt a prototype in the near future. Not sure if this has been tried before or not.....

This is my second Ox with a working area of 14" x 14" x 5" I wanted to build a small sturdy potable CNC router and this OxZilla has the nice upgrades !

Use of V-Slot for frame and rails with option to use identical 500mm uncut lengths: 8 * 20x60 x 500mm 8 * 20x40 x 500mm 7 * 20x20 x 500mm (2 cut into four identical 125mm pieces for filament holders) Use of uncut 500mm rails obtained through use of 12 joining plates for use as spacers. Alternate approach is to trim two 20x40 and 1 20x20 rail by 6-8mm each. Build volume ~400mm cubed (with dual extruders). Use of only openbuilds components! Currently in design phase...

CNC router

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...

A System of 3d printed parts to use along with your projects aluminum extrusion to cut your pieces of v-slot to length manually.

The name of the printer is G&C Printer from Good & Cheap Printer. My goal was to design an printer that was good print quality and was cheap. The total cost of the printer is about 490€.

Here is a nice little simple build that will help to free up some extra space on your work bench. If your like me you need all the room on your work station you can use, so this is great to have.

A fully aluminium printer made from off the shelf components, no printed parts.

i had som left over parts and i dit like to test the corexy control so this is wat i came up with. sorry bad englich.

A compact, enclosed Core XY design, based on off-the-shelf parts.

I ran across the OX and knew it was the one I wanted to build. Some of the things I wanted to include was make it bigger and a little more solid than what the original plans called for. So here is where I am at so far. It will have a cutting area of 48" x 48". The waste board support frame will have more support rails. The Y axis will have (3) 20mm x 60mm rails instead of the original (2) that is called for. 1/4" aluminum OX plates. And a few more odds and ends.

An X-Y Stage created from two self contained acme screw linear actuators. This build was published as an example of how many of the OpenBuilds Parts can be used.

I am very grateful to Mark Carew with passion and imagination. Therefore, the machine is good, but making the website there too daedanhaeseo The end of the same either way to invisible homework. Thank you for allowing openbuilds team submitted to the challenge once again for those with a passion that I feel like in Korea, I want to be a great help.

Creating a CNC mitre (45°) cutter, for picture frame cutting. Starting with an OX, but inverting various parts and adding a material table, with a stepper-controlled measuring guide.

Yet Another Openbuilds Router, my version :-)

A work in progress. working to refine the print head/carriage to integrate a bed level probe directly into the print head.

I am building a H bot style printer so this design will not be finished any more than it is.

I like this design a lot. It's very stable, very strong and with the EX2 enhancements, it prints like a champ.
