Low profile rack and pinion linear actuator design

High Quality CoreXY with focus on quality and optimized printarea versus physical size of the printer.

Create a ball screw carrier with out BF BK bearing blocks.

It startet in May with some leftovers from a cnc router build. Now in the middle of December its 99% finish. Everything is lowcost, spend about 1600$ so far.

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.

This build was very complex due to the fact I wanted to create a low cost larger than normal CNC. I did not want a MDF or plastic body. I wanted it to be able to do more than most CNC routers this size on the market.

This is a simple cantilevered 3D Printer. It is designed around the OB V-Slot linear rails. I am trying to simplify this as much as possible, all rails will be 250mm long and only one will require cutting (it will be cut in half). The printer will use all OB wheels and gantry plates where applicable, all other plates can be either Laser Cut or 3D Printed (files will be provided for both). I am not set on electronic as of yet, but plan to use a single control board...no Arduino/Ramps control.

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.

This project is focused on developing a low-cost, portable and open-source FDM 3D Printer.

I made a cam slider prototype with adjustable rotation to get experience for my CNC milled slider in planing.

The Routy GT2 300 BSX CNC Router is a Low Cost CNC build. It performs the same as the larger Routy's from OpenBuilds but doesn't break the bank!

Making a bellows to cover a C-beam to prevent swarf from gumming up the works.

Low cost Laser Engraver build using all off-the-shelf components.

This will be a DLP 3D Printer designed around an Openbuilds Frame and rail system. It will be a collaborated effort between myself and Ben Smith. We will be building two prototypes.

An easy simple Tape Dispenser, spawned out of necessity, and shared for the fun of it...
