Machine information

[Harjit Singh]

I'm finishing the head design for a machine and have a few questions. I've looked through the Wiki, and through the group history but don't have a clear picture. I'm hoping people will reply, and when I have my machine running, I'm happy to collate the replies into a table and update the wiki with the info.

1. What is the head pickup Safe Z Pos to maximum head down distance? 
In the picture below, this is shown as Z=-15.

2. What is the head pickup Save Z Pos to part pick up distance? 
In the picture below, this is shown as Z=-7

3. What is the head pick up Save Z to tip changer distance?

4. For the down looking camera, what is the focal length?

5. For the down looking camera, how far above the PCB top is it? 

6. For the down looking camera, what are the dimensions of the PCB area it can see?

7. For the up looking camera, what is the focal length?

8. For the up looking camera, how far below is it from the PCB top? 

9. For the up looking camera, what are the dimensions of the area that is in focus?

10. For the up looking camera, is the image warped (because of the lens focal length)?

11. Is your machine homing fiducial the same height as the PCB top?

If you have pictures of the machine, and images of what the down looking, and up looking cameras see, please include those.
