I´m having problems with one of my 2 chrosziel cdm-100 motors. 1 is set on focus and calibrates normal and functions normal. The one set on Iris (tried zoom as well) calibrates and functions for about 30sec and then stops and I have to restart and calibrate again and then same problem reappears... I´m using movi controller on a movi pro. The motors are connected to the movi pro fiz directly. Anyone have any idea?
