Intensity Ramps and Servo Motors

[Charles Belcher]

One way or another, I intend to use 2 servo motors to move a snowman's head and mouth via xLights.  I purchased a ServoDog from LOR and it works off of DMX just like their regular AC controllers--so data is easy.  I am already jumping off of a controller's DMX bridged output nearby.

The DMX value of 128 is "neutral" on my ServoCity motors and I need to ramp up to 255 and down to 0 to move the servos from the neutral position.

I read a few posts on the forum and people seem to be experiencing different results of "fading" or ramping up and down.

So, I need the channel to sit at 50% or neutral until I want movement, then I need to ramp up or down from that point to move the head and/or mouth around.

Ideas?

Use the dmx effect with a value curve.

Keith,

I watched your explanation of the DMX effect in your video training series, but you qualified your explanations saying that Gil was at that time working on changing it.  Not having a DMX fixture to watch, it is a little hard to know what all the controls do or don't do.

I thing it was in the v46 video I went over the dmx model and effect using value curves.
You can also use the on effect on a single channel model and use the brightness value curve. Same result.

I don't think he needs to use the DMX model....it's geared towards moving heads.  Keith's original reply was correct....use the DMX effect.  It's like the most simple effect in the whole program.  You map a model to the number of channels you have and then the DMX sliders control each channel.  I don't see why a video is needed to figure that out.
