Moving lights - fine movement?

Hello, is there any plan to support fine movement e.g. for Martin MAC 250 Krypton, the lamp is using two channels for tilt and 2xpan. I am not able to create fine movement to set them to Stop position. The movement is not continuous and it looks distucting. Any ide how to solve that? Thanks

Hi,

the EFX engine should use both channels for pan&tilt (e.g. 16bit positions). Obviously, there might be a problem somewhere. I don't understand exactly what are you
doing. Can you describe it in more detail, eventually post your workspace?

I know that preview area may be edgy sometimes, but that should not translate to real fixture (again. unless there's a bug somewhere...)

EFX works OK. I'm using simple scene with predefined tilt/pan channel value (Stop position). When I want to switch between EFX and my Stop position then the lights are not moving fluently.

Since Pan/Tilt are considered LTP in QLC+, the movement smoothness should come from the head itself. I can see following causes of the problem:

1. the movement speed channel has weird value (I haven't played with Kryptons, so I don't really know what the values do, though a friend of mine has a bunch of them).

2. there is some fading involved, despite the channels being LTP, and the fading is coarse.

3. something else :)

So: check your pan/tilt speed setting, try to exclude the channels from fading in Fixture tab fade button (http://htmlpreview.github.io/?https://r ... nager.html)

If that fails, post your (full or simplified) workspace so we can try to reproduce.

Here is my console. To reproduce: run "top movement" and then "stop pos" button. You will see, how the movement is uneven.

There may be some fading - but i dont understand what you mean by fading and LTP.

I see your problem now.

The question is: Your stop scene has 6 seconds fade in set, and doesn't contain fine pan/tilt channels; problem: fading is course.

The issue is that while EFX work with 16bit channels (PAN/TILT), Scenes do not (I'm not 100% sure, but from what I checked it seems so). So even if your stop scene contained pan/tilt fine channels, it would not help - pan coarse and pan fine would be faded independently and in parallel.

Quick solution for you, although not as flexible would be to use vector mode of the mac's - set channel 16 (pan/tilt speed) to something from the fast->slow range and set fade in to 0. Don't forget to set pan/tilt speed of your efx to 0 (tracking mode).
The easiest way to do it is to create "tracking on" scene (channel 16 @ 0, head will move as fast as possible, speed is controlled by QLC+) and "tracking off" (channel 16 @ e.g. 230, speed of movement controlled by mac itself). Add tracking on to triangl collection, and make new collection for the stop pos button (stop pos3 + tracking off).

I don't have any mac 250 available, so I can't check it with real fixture. I don't even have any moving head here now, so these are more or less guesses. I will try to bring a real head here, so I can check it properly.

Thanks, with tracking off it works good.
