Design Study: Rail Inline With Ball Screw

[Bravin Neff]

I would. That's what it is. Do you still think it's a thin wobbly plate? Im not being combative, it's an honest Q.

Then it's perfect and you should build it just as you've drawn it :D

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.

Honest answer, if 9mm is good in that design you can use less, triangulate and make it lighter whilst still being stronger and more rigid.
Or triangulate and make it far stronger and more rigid for little added weight.
