I use a servo for operating aperture. First I connect servo and aperture by a steel cable.
And I test. But The servo moved the aperture with all it's strength but it didn't move at all.
I find a lots of issues to be overcome with aperture system. So I decide to changing operating system.
1. Friction between the parts(MDF)
2. A low level of adhesion between the parts and steel cable.
