Q Light Controller+

Hi All

Been using QLC+ for 3 years and now wanting to get a bit more advanced and up the game of my light show

My first big question. I have 4 Chauvet Intimidator 255 irc movers, 540 degree pan 270 degree tilt. So I can set up my XY pad to be just crowd facing (forwards) how do I work out what this area is (virtually) or would I need to set them up and work it out physically moving the xy pad.

What I have currently they all seem to centre in the top right section of the XY Pad screen rather than the centre.

Thanks and hope you understand what I have rambled.

Hi,

I wrote a long post but it got lost somewhere. So here is short version:

1. PAN: 540 degrees correspond to 255 DMX steps (or 65535 if you use the fine channel). 1 DMX step ~ 540/255=2.11 degrees.
2. TILT: 270 .... 255... 1 DMX step ~ 270/255 = 1.06 degree
3. If you lay the head on the floor, tilt DMX 128 is most probably pointing upwards., pan 128 is poiting forwards. You have to check with actual head.
4. if you want front axis centered 180 deg range of movement:
PAN: 90 degrees is 90 * (540/255) = 90 * 255 / 540 = 42.5. Left end is 128 - 42.5 = 85.5 ~ 86, Right: 128 + 42.5 = 170.5 ~ 170.
TILT: since 128 is upwards, that is your top end, and since 270 is not full circle, it goes only 45 deg below horizontal axis. That means your TILT range is 128-255.

Now final adjustments:
- if your head is mounted/placed in another direction than laying on the floor pointing front face (display) to audience, you may have to either (a) reverse the ranges,
(b) enable reverse pan/tilt on the device, or (c) swap PAN and TILT axes.
- the same if it happens that the lights goes in opposite direction than intended/expected - you have to reverse some axes.

Reversing axes: PAN: left is 128 + 42, right is 128 - 42, TILT: the range is 0-128 instead of 128-255.
Swapping axes: when you mount the head sideways, the PAN is actually vertical movement, and TILT is horizontal. If you have some heads mounted normally, and some sideways,
it may be useful to swap pan and tilt on the sideways head, so all PAN channels control horizontal movement, and TILT vertical. In that case though, some PANs will have range of
270, and some 540. Similarly for TILT.

You can apply the ranges in the XYPAD, or you can apply them globally in channel modifiers.

Note that PAN is twice as fast as TILT, so to make e.g. your circle EFX even, width must be 2* height (horizontal ellipse).

If you get lost in the computations ask more questions.

Jano ... shorten your breath ...
@OP: use channel modifiers = limit the area where your movers can beam at... Simple and effective
