I’ve never got the actuator to actuate out of the frame.
I had the v2 actuator and couldn’t understand why I couldn’t get it to actuate out of the frame while pulling on the cable. If you push the housing instead of pulling the cable it should work.
I later bought the v2 actuator but because of the design of my frame and actuator the cable was at a sharp angle going to the actuator. It was constantly pulling the cable so wouldn’t stay down. I ended up filing part of my frame to straighten it up. This solved that problem but didn’t’t stop the post rotating in the frame or binding when I tightened the clamp. Someone made me a 25mm deep double bolt clamp. Now everything works fine.
