I recently upgraded to the Ronin RS3 but I have the focus motor from my old RS2. I tested the focus motor on the new ronin and it worked. But with the green light blinking instead of being lit continuously. This is a problem? Can it damage something?

It should be fine

How'd you get the motor connected to the RS3? I recently bought the rs2 focus motor as it was sold for the rs3/rs2, but I can't even get the motor to give any light at all.

Same Qas above: How'd you get the motor connected to the RS3?

I want to buy it, but I'm not sure how it works and whether it will work at all...
