Some of the things that I have done to my 1510 Workbee Installed Linear rails and bearing blocks with drawings. Installed Ops console Made conversion plates for extruded aluminum to casters Extended z axis travel by a couple inches with steel plates. As of now in the process of installing Lead screws across the 1500mm length.

Machine based on Sphinx 55 built with linear rails.

Heavily upgrading my 1200x500 Shapeoko 2... ...er, wait, scratch that... Building an all new machine, roughly the same size, that should be more rigid than a Shapeoko 3!

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

My take on a non affordable slider.

This project shows how to use Openbuilds Vv slot extrusions and wheels to retrofit a Lulzbot Taz 4 or 5 printer. These modifications improve layer consistency, eliminate nozzle and bed sag, and allow for larger toolhead mounting.

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.

DIY scratch build consisting of gas pipe, skate bearings, 12mm birch, 3/4 maple v-core ply, Nema 23's, and arduino and CNC shield with DRV8825's.

My original Tevo Tarantula kit was ok..... I had issues with the X gantry staying level. I got rid of the wheels and replaced them with linear block bearings. I still had some issues with the X gantry. I swapped out the plastic parts with aluminum which was much better. Still not what I want yet
