Design study for axis columns and stepper motor sleeve



This is a very preliminary design study for a paired column section and stepper motor sleeve of one of the three vertical axes required for a Delta Robot.


This is a segment of the herringtone rack that slots into one of the three slots on the column.



This is all very tentative.  I am trying to learn what fits together with a minimum of fuss.  I've found that if I have shapes in my hands I can see their possibilities and what wants doing with them a lot easier than if I just look at them on a screen.  Hell of a situation for someone who trained as an architect, don'tchaknow.  :-D

Delta robots? I'm not sure the advanatage over a more traditional approach. It will definiatly be heavier on the proccessor but we're nearing a point where proccessor cycles don't matter, at least not on this scale. So what are the advanatages of delta robot platforms over more tradition al methods?

That advantage that I'm most interested in is that all three axes are mechanically identical. That makes printing parts and keeping spares much simpler.

Another advantage is that all three of the axis motors are statically mounted, so the moving mass is quite small.

Tell me how you do that?
