Combination of things
5.Has your product ever worked properly?
Never got focused images.
6.What problems are you experiencing?
After you guys sent me a replacement motor control board, the servos all work now. However, the image that results is very out of focus, even after using the autofocus function in the focuserExample.py script. The image is so blurry that nothing can be made out. Do I have to make some manual adjustments to the lens before it will focus correctly?

Here is an example picture:

Thanks a lot,

Alex
7.What attempts at troubleshooting have you already made?
Reset camera (R) and ran autofocus (ENTER) in the focuserExample.py script.
8.How would you like us to help you?
I am probably doing something stupid, but I don’t have much experience with this.

Hi,

Sometimes, you need to manually adjust the focal length of the lens, because the stroke of the motor is fixed and there is a certain focus range
