That's where I got the basic idea. I just made a gantry that would hold the X and Z axis's that I already had and went with that. Works pretty good, but if I had to do it again I would have rotated the gantry 180 degrees so that the Z is closer to the centerline of the gantry and made a stronger X so that it didn't flex like this one does. 3/4" would be better for the rails then the 1/2" that I used. |
