Definable Pan and Tilt Limits

Post by MattKlasmeier » Mon Jun 22, 2009 4:21 pm

Would it be possible to have a way to define the maximum and minimum points of travel for a moving light? I have run into several instances where I need to keep a fixture from traveling the full range of travel. Most recently it was a Right Arm. If I let the fixture travel to it's maximum travel it would dump the iris. What I would like to see is a way to set the Max and Min in patch. In patch it would be possible to define it max and min for each pan and tilt. One would set the negative tilt and the positive tilt range based from zero. This would allow for asymmetrical limits and hopefully still allow for the UCM to work.

If you go to patch by output and double click on the setting for the Pan Hi (or Tilt Hi) you can set a min and max there that should do exactly what you want to do. I've used this before and it worked great!

This does work but it is a pain to set. The console deals with everything in degrees. I want to be able to set the limits in degrees too. This way I can go to the fixture pan it and see that + 70 is the max and - 85 is the min. Then take the two numbers and set the min and max for tilt. Then repeat for pan. I like the process for setting offset I wish it could be the same for pan and tilt limits.

I'm not saying that dealing in the Universal Abstract Control model wouldn't be easier. The last time I had to do this I took the fixture to where i wanted the max, switched to patch by output and saw what value in % I needed to set it for. Was pretty easy.

It does work but there are a couple of limits - first it would be nice to have to option to enter the value for min/max in 0-255 in addition to as a percent.

Second, Matt's idea of setting using the abstract model seems like a good one. This would also, hopefully, result in the user not being able to set a value out of bounds and would update the limit values in the Large Bubble.

In the current method the output is limited but the user has no feedback that a max has been reached. For example, tilt to 95deg, check the value and limit the output. On the Live screen the user still can enter a tilt of 100deg - the fixture only goes to 95deg but the Cue says 100deg. For some cases this is perfect. There are other case where what we want is to limit the range of values input.

This is much like the offset command to create a "new" home position. Sometimes you are correcting for a strange hanging position and you need to redefine home so 0deg tilt is really 0deg tilt. Other times you aren't trying to redefine your coordinate space you are simply creating a better "home" position that is not straight down.
