Setting slider limits in the Second Shooter brain (i.e. Calibration)

This one seems pretty obvious. The KOS allows for calibration to set the limits of the slide (as well as pan and tilt). Seems like this basic functionality is sorely missing from the Second Shooter brain. At least being able to set limits for the slide to avoid crashing the platform into either end of the slider.

The Second Shooter uses only 2 or 3 key frames, using the controller. You would set those key frames within the area of operation, you will not crash. The step of forcing a calibration range, that really is not needed was removed from Second Shooter to make it faster and easier to setup and use.

I agree with Matthew 100%. We just received our Second Shooter and were disappointed to see that you can't calibrate the limits of the slider to avoid crashing into the ends. We have a traveler (19'' of travel) and obviously want to use the maximum length of the slider. When programing a slide, we often find ourselves bumping into the pulley wheel which causes an error on the controller and resets all keyframe information... which means you have to start your moves over again. Its a real pain and a waste of time, not to mention you could damage the unit if you're not careful. Message to Kessler guys: You need to update the firmware and put back an optional calibration setting for those who prefer it.

Setting a start and end key frame is virtually the same as setting the start and end calibration points. It is a duplicate step that would need to be redone any time the motors are powered down or shift. The Second Shooter controller is meant to be a simple, intuitive, and quick way to setup and program a simple move that provides the functionality that most users need.

We also have the kOS software (http://www.kesslercrane.com/kos) that can be used that allows for more complex control, and also uses axis calibration. Thanks.

Thanks for your response Chris. Here's the thing:

Calibration is something you normally do once when you power up the unit. However, you can easily set the start and end keyframes literally dozens of times during a shoot. Having to pay attention to where the cart is and having to inch it along the track every time you get near the limit so as not the hit the end is by far much more time consuming and just a real pain. And this it not even considering the times where you do hit the end because you mistakenly pressed the wrong key or underestimated the cart's velocity. When this happens, the controller "crashes", shows an error and you have to reset it thus losing all your keyframe data...

Now how is that to take your words : "simple, intuitive, and quick way to setup and program a simple move" ? Sorry, but I don't agree with your analysis.

Why can't you have the best of both worlds? In the settings menu, simply add an OPTIONAL calibration mode. Those who want to "free ride" the cart with no limits AND those who prefer setting a limit and not have to worry about slamming their cart into the pulley wheel will be all the happier for it.

And isn't that what you want: happy customers :-)
