Design Study: Rail Inline With Ball Screw

[Bravin Neff]

One of my ideas was to place the ballnut inside the box section I envisaged for the gantry foot. This would give enough depth for the screw covers to telescope within the gantry. The main advantage of placing the screw outside the footprint of the frame is to keep it away from the incredible amount of flying detritus these machines produce.

It's a good point. I've been looking at various bellows and related covers that exist on the market to help with debris, and there is a surprising amount that exists.

Rather than looking for bellows search for "Wire Reinforced Hose" and suddenly there's a huge supply of reasonably priced material suitable for the same job.
