Transfer the T-slots linear bearings to OpenRail? #2

Hi G3rard, did you consider OpenRail for a linear bearing in the project? Looks like it is easily sourced, open hardware, and works well with standard aluminium extrusion 20x20.

In the OpenKnit project it would go easily with minimal changes, but to the bottom of needle beds. In this case a redesign would be necessary to the plexi cutouts, or maybe only to the 3d printed plastic pieces.

Anywho, I will - sure as hell - be building your design, once I get my head around a proper linear bearing.

Thank you for sharing!

Hi Michal, I know the linear system I'm using it's not the best option since the aluminium of the profile wears with the contact of the steel of the bearings, but is the one I had access to and also the cheapest one I could think of, and it's not that bad. Using OpenRail or similar is a great idea, I think I'll be testing that in a near future but now there are some priorities to be developed. Thanks for your thoughts! gerard
