Shuttermode with 360 continuous rotation servo

[sag007]

Hey Guys,

I have a large cover on my pool that I have installed a high torque 360deg continuous rotation servo on to open and close it.
I would like to enable shutter on this cover now and have added buttons to it for local control but Im having issues using this type of servo in shuttermode.
This servo is a 12v unit and is also 360 degree continuous rotation. With this servo the pwm range is 155 to 490, however the stop/dead zone is actually a pwm of 300. I have enabled shuttermode 5 & 6 with the following settings but this fails;
SetOption80 1
ShutterRelay1 1
ShutterMode 5/6
PWMfrequency 200
SetOption15 0
ShutterPwmRange1 155 490
ShutterOpenDuration1 10.0
ShutterCloseDuration1 10.0
ShutterMotorDelay1 2.0

My thoughts are to ultimately have at least one proximity switch at one end so I can reset the cover each time it is closed and then drive for a set time period when opening. Also to be able to control it with local hard wired buttons and/or soft buttons through HA.

Any suggestions would be greatly appreciated, even to know this isn't possible helps.
