probably as big as you'd want it...

Need to build a machine that accurately positions objects for processing by a computer vision algorithm? Here is an example of a machine that does that for a ball trajectory application. The black anodized V-rails work well for applications in optics and imaging where the machine needs to stay out of the limelight.

A 250x250 mm Delta Printer utilizing a Duet Wifi controller and a Titan Aero direct drive extruder.

This is a major redesign to the Z-axis of an otherwise stock Shapeoko 2.

The purpose of this machine is to mix two parts of conformal coating with different viscosity in exactly 1:1 ratio and distribute the fluid on to PCB to seal and make it waterproof.

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

The Story of the Scecina Memorial High School 1510 BUILD will unfold through a series of 10 minute Episodes. Each episode will consist of video showing how to assemble some aspect of the 1510 overlaid with a discussion about Technology, Art, Philosophy... and Life the Universe and Everything. Episode two is soon to follow. If sufficient interest ensues, the episodes may continue beyond the building of the 1510 to relate its use in the making of the Art.

All metal frame 500mm bed Delta 3D printer

The machine is a stock Lead CNC, with the Black Box controller and StepperOnline 269oz NEMA 23 motors. I'll be using the DeWalt 611 from Openbuilds, as well.

This is an automatic cocktail mixer made with 8 small peristaltic pumps. this is driven with the touch screen or over wifi. the controller used is a raspberry pi with a Apache webserver

The Feedback Fractal Project (Project) - building "A Monument For Our Time." As its intent is to build a monumental sculpture, the Project will produce an object d'art. Yet, once begun, the Project has evolved a life and character of its own. I continue to follow the thread woven by the materials, the processes, and the people that come to it and in the end the work will not only be a faithful rendition of an image and a concept, it will also be a tapestry of the story of its making.

i had the ox build and wanted to do a more beeffer style so i went with a workbee style machine ..

Upgrading my CNC router to run on ball screws. Me and the belts where not getting along.

Getting an accurate scan of a golf ball can be difficult with general-purpose 3D scanners. This purpose-built golf ball scanner uses a very accurate Keyence LK-081 laser displacement sensor with an Open Builds linear actuator for the vertical axis and a Sherline CNC rotary table for the turntable. Scan detail is determined by the sample step size and can be set arbitrarily based on desired scan time.

This is my first build attempt, a large form (4x4ft.) 3 axis 4-motor CNC router table, . The build components are Baltic birch plywood, stepper motors, SBR linear bearings, and ball screws, LinuxCNC, Mesa controller.

I know this build is a little off category here at OB, but I wanted to share it with the community (as well as other coffee lovers) and show however vast the possibilities are when OB hardware is involved. This is a powered stand intended to operate a manual coffee grinder. It is compact, light, portable and uses simple drive components (B&D Cordless Screwdriver). I will post two version, V-1 (Beginner skill level ) and V-2 (Intermediate skill level). Both accomplish the same results.

How to build an Independent Dual EXtruder (IDEX) 3D printer from OpenBuilds parts.

Super solid core xy build inspired by the e3d tool changer

DIY design and build of a roughing 2' by 3.5' CNC router

This is a lead 1010 build that I wanted to have a little fun with. I purchased the whole Lead 1010 kit, and felt like studying a few shortcomings of the original to see if I can improve it or just have some fun with it.

Build features include a double c-beam gantry (bonded & mechanically fastened), linear x rails, custom gantry end plates, a custom linear rail & ballscrew Z axis, and custom lead screw tensioning plates. The primary goal was to remove twist from the 1500mm gantry & stiffen the Z axis.

My goals for this build were to eliminate slop and flex while also allowing easy serviceability.

Hobby project

Modular and Scalable CoreXY Printer with all metal parts.

a dual extruder build using direct drive for flexible filaments

This is the build of a cartesian 3d printer made of an old Anet and Geeeteck, some 2020 alu profil and linear rail. Powered by a Rumba with a Nextion screen. It should be modular and accept dual Extrusion and laser engraving.

Cartesian style CNC with a working area of around 360mm x 360mm x 120 mm (X, Y, Z) using Linear rails and ball screws. The linear rails are (Hiwin?) HGR 20mm x 520mm and the ball screws are SFU1204 (12mm lead 4mm) of around +/- 430 mm. The base structure is made from rectangular aluminum profiles of 70mm x 45mm x 3mm (thickness of walls).

Machine with 12,5Nm closed loop steppers or servo steppers

PeeNaPle_V1.4b is a BoB controller board for 3D Printers, CnC and cartesian machine, using the latest Teensy_4.1

A beefed up minimill, ready to gnaw on some aluminum! HG15 linear rails, a thick heavy column, bellows and easy fixturing and tramming.

Anti-Twist Design, larger lead screws, enhanced M8 wheel sets.

The idea was to use materials from previuos failed projects into a succesful one. I have build this tiny but powerfull CNC machine mainly using the universal gantry plates for the X and Y axis. Also another innovative part is the fact that I assembled the Z gantry with 2 aluminum sections of 20X40 and one aluminum seccion of the 20X20. I used NEMA 17 stepper motors with GT2 pulleys. This was designed on Fusion360

This is a K-Cup sealer i constructed does a fine job

Ball screw drive, linear rail CNC Kit

Attached to a scroll saw you can cut nested wooden spirals with this jig. Make two, three, four ... interlocking spirals that unwind/unscrew. Fascinating toys or art objects!

Building a printer that can fit inside and operate at ~200 C oven temperatures

I have tested my Opt Lasers laser module on a "open" frame for some time. Decided that I want to test a corexy setup and combine it with a boxed/enclosed design - my goal is to get high precision + a safe setup with protection from the laser light + a fan to extract the smoke/exhaust..

Had left over parts from cnc plasma build.

All metal CoreXY 3D Printer Design with triple z, kinematic bed, and scalable corexy mechanism.

I decided to start designing this printer, this will be my solution for a more rugged printer that you can use as workhorses...

I have not too much space and need a portable solution, and tired of cleaning the electronics I decide to put everything inside a box and this is the result.

This is based on core XY kinematics. First of all, we designed a CAD model. Most of the required parts are designed by us in solidworks software, and some parts are downloaded from a web platform ‘grabcad’. After that we assembled those parts and inspected them in solidworks. The designed CAD models are frame of 470mmX392mmX545mm SBR linear guide rod, linear guide holder, lead screw, motor mounts, pulley, bed mount, idler block, timing belt clamper.

long overdue overhaul of 1000 x 1000 machine

LEAD 1010 PLASMA Add-On is a great modification you can do for your LEAD 1010 to convert it into a metal cutting monster machine!

I designed and made this from scratch. The frame is welded steel filled with sand, and most of the other parts are aluminium. It's controlled with a DIY ESP32 controller running GRBL_ESP32
