    I have these Octopus III servo control boards and using their Octo III remote board to program the controllers there appears to be an option to control the sped of the servo but I can't figure out how to do it.

    There is absolutely NO info on how to do this in the literature they give you or even mention of this other than something on the board itself that it is possible.

    The turnouts I'm using are N scale Peco code 55 Electrofrogs with the spring intact (which I want it to be). Anyone that has these know what the procedure is with those 3 buttons on their programming board??

    Are these still available, 2 dealers claim they aren't?

    If not, what else is available for servo turnout control??

    You might try LitchfieldStation. I recently bought boosters, circuit breakers and a hex frog juicer from them. It sounds like the servo controllers and a number of other items are going out of production, at least for a while.....

    Thinking of Duncan and hoping for the best for him. He has been a huge contributor to the hobby.

    I know you aren't too interested in DIY but the ones I've posted about ( HERE ) can be made in under 30 minutes for under $8 and that includes the servo and a switch to throw it along with LED route indicators. The controller has a wide range of control over the throw but doesn't have any control over the speed of the throw. I'm betting someone smarter than I am could add that also.

    Thanks, but that won't work for me. I set up the control panel for a single pushbutton switch & a hole for a single bi-colored LED and that's all. And there are 60+ of them (count based on xovers are one instance)

    I see these Pololu controllers, but those are PC command line/script driven which is another factor (more confusion and complication).

    Understand, I could see how that could be done with a latching relay instead of the DPDT toggle switch I'm using but don't need that myself.

    Did you get the throw speed figured out? It is explained in their instructions here...

    .... although I'm wondering if the wording is exactly right as far as the button sequence,

    I decided to sell what I have. I'm going with Berrett Hill out of Maryland.
