We experimented a little with these linear slide bearings as well and moved from there to creating barrel type rollers that would ride in the extrusion but the barrel rollers allowed for too much play. It was necessary that they did not wiggle at all on the rod. They just had too much play in them to allow for any kind of precision when it came to an H-Bot. We ran into the same issue while working on an H-Bot design. I know what you mean about having to shim the linear bearings.

I am going to check them out in more detail asap! Wow! You have been working on a lot of cool projects. It's very cool how quickly you can put together a machine using V-Slot as an actuator along with these mini carriages. We wanted to make it as small as possible so that it will work along the same principle as a block and rail system as well as being the mounting blocks for the modular system. We are using it for some of the modular machines. You can see a couple of uses for that particular plate/wheel design on the KickStarter page gif. So, not only can you use it on the 20 x 20, but you can also use it on the 20mm edges of the 20 x 40, 20 x 60, and 20 x 80 as well. We have been working on creating the smallest possible carriage that we can that will ride on any 20mm width edge of V-Slot. Thanks for your reply and your input! As a matter of fact, we are working on a smaller wheel type. We hope that you will help make this tool available to everyone by spreading the word and helping to bring V-Slot to the world! The Internal V Track allows for multiple Dual V Carriage Mounting Configurations and Orientations while the same structure allows for the well known T-Slot type modular building systems. OpenBuilds V-Slot is sure to offer the most builder/designer friendly experience on the market. One of the many benefits V-Slot offers is its sleek, tight design with no protruding arrows or other obstructions to get in the way of an ultra-minimalistic low profile build. We hope that all will benefit as a low cost completely Open Source alternative to T-Slot extrusions.ĭesigning and building linear actuators that are integrated into the structural frame itself is now a reality! [ These are just the tip of the iceberg of things that can be done with this system. In short, its an aluminum extrusion with a built in v groove for linear motion! It has a lot of cool applications as you can see here: We here at the OpenBuilds Team have come up with a cool new tool for makers and we wanted to share it with the RepRap community!
