Ok so getting back in the groove of things I have some screen shots of my two current models.
First the one with the lead screw mounted on the back similar to joe's design, this is still very rough and I am just trying to get an idea of where to locate things. I dont think there will be much of a difference between mounting the beatings vertically or horizontally.
The pictures show mounting holes for a nema 23 stepper, but because the screw will be belt driven i should be able to shave that down quite a bit.
The second shows the cut out that would be needed to run the lead screw inside the y axis. I am not skilled enough to do a stress analysis of this model so I suppose it will be best to leave this idea for now.
I want to get the x and y situated before I start on the z axis. I may have some more time to work on this tonight and if so will post updated images. |
