Stronger frame for Prusa i3 MK2(s), MK2.5 and MK3 3D printer

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

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".

I built the original machine using plywood plates, and always intended to upgrade those parts to more durable ones. I decided to go with acetal as it's a lot easier to cut than aluminium. I used fusion 360 to model and rebuild the original machine. Once I have assembled everything and feel confident it all works I will release the plate designs here.

Upgraded Z-axis for Sphinx-style CNC using ball screws and linear rails.

Replaced the original Z-axis for a shapeoko with a c-beam upgrade. This upgrade required a nema 17 mount and a quiet spindle mount I printed with a 3D printer.

Somewhat Simple Lead screw conversion for an OX CNC.

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.

Upgrade your Minimill with an off-set Z Axis Motor

This is my first public build. Please be kind. We upgraded our C-Beam to the C-Cbeam X-Large. I want to give special thanks to Moag and the OpenBuilds team for making this happen.

Using criticall OpenBuilds components to upgrade the rigidity and reliability of an X-Carve 1000mm build.

This is a pure cbeam build to maximize envelope and rigidity. All the parts used are available from open builds.

Currently completely imaginary

Another (R)OX CNC something like build, in French please ! Pics Heavy !
