Movingheads move a bit shaky

[Kevin88]

I have 6 Chinese 60 watt movingheads and when doing a movement on a slow speed via the move fx the move a bit shaky like something is holding them en than going again. Its not completely smooth. When I move them with a different controller on low speed they don’t seem to do the same. Is this something that could be off in the profile?

I made a profile that works good in the visualizer but that makes them go crazy when use them in real life. They start shaking wild when loaded and I don’t have any control.

The profile I made myself on the wmx works fine but that have the movement as mentioned above.

I wanne try some different profiles to see if I can get the gold a go movement out of it. This starts with speeds around 30% and lower. It looks like it’s more there with the figure 8 movement. Like it’s not using its full 16 bit.

Question: is this a profile thing or maybe just the fixtures? Its a bit weird all 6 doing it

It could be a "faulty" profile, when the 16bit channel (micro or fine) channel is not configured correctly, i.e doing 2x Pan & Tilt instead 1x Pan & Tilt (8bit) and another µPan & µTilt (16bit) for correct configuration. So even when using the "hi res" channel mode, you actually using still an 8bit profile.
You can only verify by loading the profile into the Profile Builder and check if it is 16bit enabled or not.

Another issue could be your "connection"....is it wireless or do you use DMX cables? Wireless can also be erratic (unpredictable) when it comes to smooth connectivity.

Hi Axell,

Thanks for replying.

The cable thing isn’t the case for sure case just connect one light the same problem occurred. Always use everything wired. In general I’m not a huge fan of everything wireless.

The profile I use does have 2x pan 2x tilt with the 2nd set to fine for each. Gone try it this evening in the profile builder to see but I assume the 16 bit is on. But to be fair it looks like it’s moving on 8 that shaky movement is what I’m seeing.

load a new project (HOME -> SETUP -> PROJECTS and then NEW...and NEW again)
Patch ONE Mover to DMX address #1
make sure using the same Channel Mode on the fixture as loaded profile mode on Wolfmix
Select and activate your MoveFX pattern (i.e. Circle) and adjust a REAL sloooow Speed (i.e. 3%)
Now switch to HOME -> SETUP -> DMX Values and monitor the Pan/Tilt and µPan/µTilt channels numbers (according to the Manual) and verify that Wolfmix is sending data on these 4 channels (counting up and down, where the 2nd (µ) Channels will move much faster).

I’ll try to see if it works making a new profile in the profile builder and see if this is any different.

Any idea why a different profile I build make the heads shake wildly?

[axell]

no, i need to see the profile you did to analyse what makes the head shake.
eventually (also) a double assignment of pan/tilt can lead to such reaction, but i am not sure

Hi Axell,

Found the problem why the head was shaking its was a default setting in one of the channels.

BUT

The movement is still weird… you know what’s the most weird? When I move only the pan in the dmx value screen slowly it’s more smooth than in the move FX engine is there a way to send you videos?

It doesn’t add up it’s almost like the fine pan works against the normal pan in the fx engine.

Yes when I make both the pan the same it starts working in 8 bit but it isn’t fighting against the direction of the movement. This is super weird. Do you know any solution? It’s as if the pan wants left and the fine pan goes right what makes this friction movement that makes it go back a little.

When now tried super slow it’s like when the fine pan starts from 0 again the head goes back a little so end of the step basically. Same happens with tilt on super slow. It’s like the fine pan or tilt works a little against the normal

I even found this doesn’t happen at a speed of 23% but comes again higher or lower. But this is also depending on the size of the movement

I’ve made a video how can I get this to you?

[axell]

To look at a video does not help, as I only see what you told me already. I can't see anything else.
To FIX I need to see the PROFILE you are using...just export the profile and upload here, so I can have a look.
(it would also help if you would tell me the brand and model of the fixture you have problems with!)

[Kevin88]

Well the video kind of shows its signal related cause 2 same fixtures on the same side are doing exactly the same pause at the same time. And on the other side the same thing.

I found that it looks like the pan and fine pan aren’t lined up correctly. I’d happens with different profiles. Like the fine pulls back the pan. I’ll send the profile I’ve used in a bit but I don’t think there is a problem in the profile after all.

The head goes back a little when the fine channel starts from 0 again.

Fixtures: Hong Yi Stage Lighting HY-GP60

I’m only talking about the movement now. The wild shaking default was in the profile cause i found that one default setting was on 127 instead of 0

I’ve tried a other fixture and looking very close it seems like I’m seeing a bit of the same behavior. It looks a bit smoother but it’s a wash moving fixture so it’s a bit harder to notice. When setting the fine channel on test 0 it’s gone.

The problem seems to be that the pan/tilt and fine are not perfectly lined up. So the fine is a little behind pulling back the movement a little. Is this something heared before? I would love to send a video to see it.

[Kevin88]

This is the profile but i don't think the problem is in there because like i said i've check with 2 profiles and a 3th for only movement and its basiclly the same.

I don't see it in easyview to be honest.

Here is a link to a video of the behavior.
