CMY 575 rotg Tab2 error

Im having an error with my gobo wheel 2 rotating tab error... Im not seeing where i could be getting the error from. I thought maybe it was the teflon washer so i changed that out. and now it seems like i'm just taking it apart and putting it back together for the hell of it just to have it read ROTG TAB2 ERR.

If anyone could help me out with what it could be it would be greatly appreciated... I've taken it apart just to put it back together atleast a dozen times changed out the motors and cleaned the sensors made sure the sensor tabs were reaching the sensors... I just don't understand what i'm missing...

my email is it goes directly to my phone since i'm never anywhere near a computer all day long.

thank you so much
