It is a simple project - a focus system for a taken lens and anamorphic adaptor. I have three pots. The first one I use as a manipulator. The second is used to get the position of the continuous rotation servo motor#1. The third pot is used to control the position of the other continuous rotation servo - motor#2. Motor#1 rotates the taken lens and motor#2 rotates the adaptor.
Old lenses are very stiff. I've tried Doman, but it has problems with CCW speed, then I've tried JX, but they consume to much current.
By the way, what do you think about JX coreless servos like PDI-HV7223MG?
