This Belt and Pinion actuator is a great example of how easy it is to convert your machine into a belt drive system.

This easy to build and effective system can take your builds to the next level! This design is strong and accurate and could be the solution/upgrade that you've been looking for!

The aim of this design is to build a simple, cost effective (under $1000) and relatively compact large volume (m3) 3D printer that will use a pellet extruder to create art/design objects using shredded recycled plastics.

Low profile rack and pinion linear actuator design

The Ooznest OX CNC Machine Kit is based on the OX CNC Machine designed by Mark Carew, and it incorporates many upgrades from this community. The plate designs in our kit are based on the originals. However we have added our own touches to increase the performance and design of the machine. To complement Mark's build videos, we have made a complete written instruction manual, with IKEA'eske assembly diagrams.

The OpenBuilds Sphinx 55 - 500x500 Lead Screw Machine

This is a Sphinx variation, aimed to minimize footprint and maximize workarea. Work in progress.

This is a rework of a previous build I did on here, a mostly printed cartesian CNC. Initially intended to just be an update to that, but so many things changed including the linear motion and every single part has been modified significantly that I felt as though it deserved a whole new build.

Crypto Mining rigs with vslot rail

Rigid variant of the C-Beam sphinx platform

Working progress.

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.

Current progress uses existing openbuilds bearings, but also uses 8mm shafts (custom)

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.

I'm conducing guitar loudspeaker cabinet fabrication technique research (material type/thickness, mechanical joints, adhesives, etc) and how these relate to cabinet/speaker coupling and enclosure resonance with respect to psycho-acoustics. Basically, does one speaker cab sound better than another and why?

After use of the i3 Prusa 200x200x180, the volume increases to 300x300x450 on the V-Slot and driven by a Megatronics V3

The Tiger Paw will be a 1000mm X 500mm Cartesian style CNC with the Minimill attached to the end. It is named the D&R Tiger Paw because my son, Daniel, and myself, Richard, will put this Tiger strong and fast machine together. Our goal is to have a Tiger strong build with a Paw print that wouldn’t take up a huge amount of space in our garage.

Hopefully this will be a quick guide to one way that you can add a laser to an existing CNC router.

This will showcase the build of my Rawcnc 1.5. A rigid cnc router from the Swedish company Rawcnc, featuring a rather cool linear motion system, rack & pinion and steel reinforced X-axis capable of milling aluminum.

CNC Mini Mill build with some mods after following standard build on Youtube video.

Using most of the parts of the MiniMill, and adding a few other parts (cost < $200), transforms the MiniMill into a very capable machine. Final build area as shown is 10.25" x 16". With a custom Y-plate, I will take it to 10.25" x 20-24".

A quick little mini mill build

The OpenBuilds team has redefined the belt and pinion concept. By using standard OpenBuild components were able to improve on this system in ways that will save on cost and enhance its engineering capabilities.

Minimill bundle, but with an extended X Axis

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

The search for an affordable hobby 5 axis machine.

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.

Some enhancements of the basic mini-mill

Gantry style rigid build

This is my latest printer build. The second printer I've built using V-Slot.

Large format CNC router with a 1500mm x 3000mm cutting envelope (5 x 10 ft) strong enough to cut wood and aluminum constructed from 20-series and 40-series aluminum extrusions. Complete Project Log w/ Pictures: https://goo.gl/photos/Co81AvGwVijE2zow9

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.

Another MiniMill, different to the OpenBuilds version and potentially more flexible because of the design.

C-Beam based CNC with Rack & Pinion (for the X Axis) and lead screws (for the Y Axis)

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

Next up will be the electronics package. My parts bins are overflowing with boards so this may be the hardest decision to make of the entire build.

All-in-one OB Minimill

I am building a simple home brewed printer. I have a background in industrial automation so I figured how hard could this be. The mechanical build was pretty smooth as was the electrical side. Now just getting plastic out the hotend is my stopping point.

I will post soon some more details.

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

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

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

Wanna quet an nice looking device done by my hands

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.

I have been working on this project for something like 3 years on and off, sometimes leaving it for a few months. Now I really want to finish it. For me, the mechanical part was the easy (though long) part because I get to use about 17 CNC machines and MasterCAM and I am a machinist. The hard part is the electronics part. Had a few problems getting Windows to communicate to the X5 Mini via the USB cable but found something on the Smoothie forum and got the machine moving.

You are about to read the evolution of my 3d Printer build.

A 3-axis flying gantry (4'x4') mechanical kit is assembled. A 3D printer is used to make cable chain for tidy and cheap wire management. A BeagleBone Black development platform with Machinekit software (LinuxCNC) is configured to control a Xylotex motor driver box connected to an Openbuilds Ox direct-drive pulley and belt motion system. A vacuum dust-collection system is designed, CNC-routed and installed. A steel table is made to mount the table onto.

This slider uses an 500mm OpenBuilds C-beam and the design is such that the effective length of the slider is slightly less then twice the length of the C-Beam. It can be used both motorized or not.
