For the frame I know there is a lot more to be done on it. I understand of what you said about the thicker top rails and I will make a note of that.

As I said before am really new to all of it and I was under the impression that all motors will be the same to have easier setup. But if that is not the case I would be glad to go with something smaller for the Z axis. When its comes to the drivers and power supply I rather buy these with the advice I get from you all. It will be a bit more money but will be faster to have the build started up early next year.

With the ball screw, yes I do want speed, and I will put those you suggested in my list of stuff I will need. But when it comes to the 20mm and 25mm ball screws I don't know how to cal such.

The belt I was more thinking of that but I hit a stop when assembling and tension of such came into play. I don't know how to design that section of it.

I will also put that spindle into my list. When that time comes for me to buy anything I will post up my list to make sure I have everything in order.

When you say other electronics, I did not dig into it due to the fact that, I taught when I buy a kit I would attained all of this. But as you mentioned, there always compromised in at least one area. So I will need some help with that if you all don't mind. When you say the controller, do you mean the breakout board?
