Fixture troubles

FM Former Member
I've built a LED par 64 fixture
when I use the FX generator all I get is one color. I think it's a problem with the fixture I have built
Could some one build one for me to see
Channel 1 = dimmer
0-152 = dimmer
153-242 = strobe
243-255 = full on
Channel 2 = Red
Channel 3 = Green
Channel 4 = Blue
Channel 5 = free

Thanks

Why do you have a free channel? What do you think you are, Ch**vet?

Bad joke. We discovered a fixture with an open channel for what amounts to no apparent reason.

I don't have the time to build you a profile. I barely have time for this.

First, I'm not going to question your fixture. It may be fine. Does it work with a hardware controller? If yes, then it's not "you".

Sounds like the profile is the issue, and there is the possibility that the FX generator may not like what it's seeing right now.

Suggestion, since you've built your own fixture and you have that open channel:

Make channes 1, 2 and 3 Red, Green Blue respectively. Put your strobe on 4 and dimmer on 5. It makes more sense logically.

Regardless, that's not the issue.

Regarding your re-doing the DMX instruction set for your custom fixture:

I don't know exactly how the FX Generator works, but my thoughts are that it should read the profile for the lights selected, and then it should be able to essentially treat this the same as anything else that is similar in functionality.

My thought process with RGB mixing lights is "RBG values to determine color first" and then throw dimming in at the end, not as an afterthought. Clearly you haven't treated dimming as an afterthought, and I like how you set the last bit of the dimmer/srobe channel as full on, which is great for panic mode operations: slam channel 1 full on and you got lights. Seriously, that's a nice little function, so you've done a bit of thinking about this. Back to my opinion the only thing I want on a dimmer channel is dimming. During an event if I need manual override, the last thing I want is to remember anything. I don't find myself needing to override dimming when I'm using DMX, at least so far. As we know, stuff can change.

Again, just my opinion. Take it as you will.

Leaving out the issue with the FX Generator, do your lights otherwise work properly with MyDX? I guess I should have asked that in the previous post. It's always important that the light is working as expected first. If that doesn't work, there's no way one should expect the FX Generator to work properly. The FX Generator has to have the profile working correctly as well.

So, I guess the rundown for things to confirm:
1: Are the lights behaving properly in MyDMX.
2: The creation and testing of a profile. Then further testing with the profile in MyDMX.
3: FX Generator.

Also, how many of these things to you have? Seems a bit silly to use the FX Generator with just one fixture(or at least a color changer)

The lights operate perfectly with MyDmx
Only when i use the effect generator is there something wrong (only get blue)
Blue is the only color that shows up in the fx generator screen
So I'm guessing thats where the problem is
This is what I have:

10 led pars
10 color changers
4 moving heads
4 scanners
8 octopods
4 lasers
and various others

I'd definately have Jingles do a look-over on your profile work. It's so easy to make silly mistakes on your first attempt. It may be as simple as that.

It could quite literally be that the FX Generator doesn't know what the heck to do with your fixture.

My opinion on how to re-assign your channels is based on other fixtures I have, which are, to be precise are the Color Fusions, an the 64 LED Pros, which are very similar in functionality. Both do use 7 channels. 1,2&3 are RGB respectively, there is a dedicated dimming channel, but I think the Color Fusions use channe 5 for that while the 64 LED Pros use channel 7(in 7 channel mode). I'd really have to find the manuals to find out how similar or disimilar they are.

Not to try to make extra work for you, but could you post up some screen shots or something so we can see what you'd doing? I have issues with the FX Generator as some things don't make logical sense to me, but I'm still learning it.

The good news is that the fiture is working in MyDMX. That's positive. Does the 3D Visualizer reflect accurately what the fixture should be doing?

Cool. Glad to hear it.

It's too easy to make mistakes with profiles for those just starting out. Even for more seasoned guys like myself, it's still easy to make an oversight. So far, I'm made profiles for my Chauvet lights and they work fine, and Jingles checked my Q-Spot 150 main profile, which I then hacked to work in the other modes that fixture offers.

Crisis resolved. All is well. Enjoy!
