Three things needed to be fix:

• All setpoint are without ".VAL" at the end of a pv.
• No real fix, current we can change it after initialise motor class but will have to reconnect to it, may not work with standard blue api.
• The three angles pitch roll and theta are not standard motors, they only have set and feedback and it is not stopable.
• Created a SetReadOnlyMotor to capture this.
• Filter wheel is not motor
• Made a FilterMotor device for p99selections
