ML Pan Problem

Just to understand the problem a bit more... When you try to control these cheap MLs from the ML Controls Screen (not the light hack) they do work, but for some reason when trying to control from the Lighthack box initially they are non responsive. 

My initial thought would be that it might be that the light hack is sending a value (more granular) to those fixtures which is causing a problem with them, but when you use the more course control of ML Controls, then they avoid those problematic DMX values? Are the 8 or 16-bit pan/tilt fixtures. I wonder if it is something like that. What is the actual fixture and what fixture profile are you using on the console?

"150W MOVING HEAD Mini BEAM SPOT LED" is all the booklet reports.

I think you are right. Some other things I have noticed are a definite inertia when the pan control is used on the Lighthack: IE When I turn the encoder, the ML moves in a granular fashion (as though the fine pan isn't working). And, when I stop turning the pan continues! Very weird. You point it to a spot and then it continues moving for a short time!

As my Lighthack seems to do a good job with a variety of other MLs we operate, I'm not sure how to deal with issue.

Fortunately for this show I'm using some effects on four of them and they are behaving. 

A few things to try:
1) Try using a 8-bit pan/tilt profile on the fixture and EOS (if possible)
2) Try swapping the fine channel (pan 2, 1) and tilt (4, 3) -- I've seen these messed up in cheap fixtures before.
3) Make sure you're using pan/tilt with those fixtures instead of XY or XYZ...

I have got these to work in an effect for "Annie" opening in a few days so dare not touch them.

Which brings on an interesting question: Where does EOS save fixture profiles? In the show file or in a separate place that all show files access. What I am wondering is, if I save my show file to something like "temp" and then experiment with the profile for these MLs. and mess it up, then open the proper show file will those mistakes now be in the show file?

The profiles are saved with the show file. So you could save a copy and then tinker with that other show file. However, I would do something extremely obvious in your temporary copy so that you don't accidentally get the two mixed up... Mostly to prevent the situation where you go home with the temporary file loaded, and then come back in the next day forgetting the main show file wasn't loaded and start making changes.

I can see how that could happen. I've renamed the whole show file "DJFX_EXP" for editing at home. I've changed the Pan from 1, 2 to 1, 3 and tilt 2, 3 to 2, 4. I'll try these Monday and let you know.

your Pan and Tilt numbers make no sense.

You are mixing Pan & Tilt into each other. Seeing this is a planed error, in my eyes.

Not sure on this. The instructions call for Pan on 1 and 3 and tilt on 2 and 4. I have other MLs that do the same. I experimented using 1 and 2 for pan and 3 and 4 for tilt which went totally haywire. Is there something in there I'm not seeing?

It is extremely RARE to see them not paired up as 1/2 and 3/4 -- but I guess on some cheap / knock off fixtures it is possible. I've never worked with any fixture where the course/fine controls were not directly next to each other. It is worth doing some testing to see if one is more reliable than the other -- a trust-but-verify situation.
