CAD is done!!! Most all the orange plastic parts are already printed. The white arms will be laser cut on Monday. All the vitamins have been ordered in duplicate (gotta replicate) and are racing towards me as I type. I am so excited. This thing might breath as early as next week. It was 20 days ago that I seriously started thinking about making a 3D printer that has no linear rails and low center of mass. 10 days ago I hit upon this basic geometry that allows a delta robot to actuate the elbow instead of the shoulder. 10 days in the future I hope to have this thing done with enough documentation to enter the Gada Prize.
Here is some Youtube candy of my machine. Note: I have all the parts that you see made except for the white arms. Vitamins should arrive end of this week or early next week. I can already tell you that wiring is going to be the biggest hurdle. Firmware could also be a challenge since I have never modified firmware before. The geometry is easier than a Rostock so I will probably just steal their codebase and change the geometry. I hope it is that easy.)
I am putting a 15" round platform on Simpson and he can reach almost every inch. Under the glass I am going to put a 12x12" silicone rubber heater bed. (I understand that it will stick off some.) I am quite sure that this is over kill but most every position on the platform is reachable so why not use it.
@qharley: This isn't real for me yet. I feel so fortunate. I am jealous of what you have already achieved. I am trying hard to emulate you.
