Movingheads move a bit shaky

[axell]

The profile "looks" OK (Pan / µPan / Tilt / µTilt are OK)
2 (3) more possibilities.....
a) verify the Pan/Tilt channels set in the profile are exactly as in the Manual. Sometimes i could also be PAN/TILT on Ch1+Ch2 and then µPan/µTilt on Ch3+Ch4
b) check "Programs" channel (ch 11) to have a No Function with the DMX default of 0 (not 25 which it is now - it eventually activates an undefined Macro with a higher DMX value as 0)
c) Using MoveFX Speed not faster as 30%-35% max. Small Movers are not the fastest and often cannot handle the Speed Wolfmix is able to send.

And I would -again- check if the Wolfmix indeed is sending out the erratic Pan/Tilt values by reading the DMX Values for Pan & Tilt, if they send values up and down in the same way as the Moving Heads are moving back and forth (stutter). If Wolfmix is sending the values steadily from low to high numbers, then there is something wrong with your Movers, where Wolfmix is sending the right data.

Thanks again.

The values going up and down in the dmx value menu like they should.

The other points are checked but doesn’t seem to be the problem reason. It’s obvious when the movement is slow not when it’s fast.

I’ve pin pointed the problem in a miss alignment in the restarting of the fine channel. So when the fine channel starts from 0 or 255 it’s not in line with the normal pan/tilt so it gets pulled back. Not sure if this is something that can be fixed.

This shows it pretty clear: https://youtube.com/shorts/_zeR5jB17R8? ... 3-bJLS4fg4

is there any "automation" effect which restarting the movement that frequently? Normal movements you should not notice a microPan offset at all. It is just a tiny 255 part of the 8bit step....
For testing purpose you can "nail" the 8bit (coarse) Pan & Tilt channels (ch1+ch3) at a fixed position by using a Live Edit and just let the fine channels (ch2+ch4) running the same effect again...so you can see the max micro movement and also if it is skipping (stutter).

You can also "block" the 16bit channels (ch2äch4) and let the 8bit running solo and see if they afe working better without 16bit fine channels.

The movement in the video is the normal left right from the fx engine on a slow speed.

I’ve tried what you suggested but when make a fixed value for pan the fine channel is automatically set to 0 and isn’t possible to reset. So the movement doesn’t run.

(Edit: I found a way to try this and the movement is working smooth when only controlling the fine channel)

When moving the fine channel from 0-255 the fine momvement is normal and smooth.

It’s a weird issue. What makes it weird in the first video I’ve send is that they all do it and the fixtures on the same side with the same limit settings are doining it at the exact same point and time.

Could it be that depending on the choose speed of the fx the fine channel timing gets a bit off? It looks a bit like its signal related to me. I mean when it’s just one fixture it can be the fixture but all doing the same thing is just weird.

Is there a way to limit the fine channel for example just using 50-200 instead of 0-255? Maybe that can solve this? When I set the min & max in the profile to those values the dmx value screen still goes from 0-255. I think narrowing the fine movement channel could fix the issue here.

This option isn’t in the setting menu of the dmx value screen either normal pan and tilt is but not for the fine channels. Maybe this is something that can be added in an update? Like I’ve said I think narrowing the window of the fine channels will solve this.

To be fair it could be that the fine movement in the fixtures is to wide but like suggested narrowing the window for it could be the solution to solve this. Maybe wolfmix could make this possible?

2 things:

1) YES, you can limit the µPan and µTilt channels.
Go to HOME -> SETUP -> DMX Values and select your PAN (or Tilt) channel number. Now in top right select the "setup" gear/wheel to enter "Beam Editor.
Left column are your fixtures, select your Moving Head, in the middle you see the channel TYPE (select whether it is Pan or Tilt).
At the bottom adjust the DMX MIN and DMX MAX to the values you want to have - done

However, I "guess" this will not give you the result you expect. You now start with µPan and µTilt from 50 -200 only, you will have a "gap" as well when switching from one value to the next on the 8bit channel. It now does not start from 000 -255 before switching to the next, but "jumps" to 50 and at the end "stops" at 200 and then "jumps" again to the next 8bit value - so it is never running the the full range inside:
Example (the micro steps are in brackets)
Pan value of 37 ...and then starts at 37(000); 37(001); 37(002); 37(003)....37(253); 37(254); 37(255); 38(000); 38(001);38(002) and so on
Now when you do NOT run the full micro range, you have a gap of each 50 micro steps on each side, which "jumps" to it.


2. I would rather create quickly an alternate profile where the micro channels (ch2+ch4) are just Channel Type "OTHER" with a default value of 0 and see what the head is doing just with the coarse 8bit (main) Pan & Til channels

Hi Axell,

Thanks again to think with me.

I found that indeed but this seems to be the normal pan and tilt set by the selected limits correct?

Just checked again by setting the pan dmx min and max you set the basically the movement limits. This would work as this would also be possible for the fine channels.

I don’t see this for the fine pan or tilt. Am I missing something?

(Can’t add a picture)

I see and understand what your saying but I kind of get the feeling that the full movement from 0-255 is to wide to fill in the gap in a step from the normal pan/tilt (8bit) movement. So when it starts at 0 it goes back a little to far. I think there could be a sweet spot where it can be right. Or at least that is what I assume and maybe hope a little.

Tried option 2 allready works but indeed as 8 bith with clunky moves

[axell]

slowly running out of ideas ...
Have you thought about to open a ticket with Nicolaudie and asking about the erratic behavour of the micromchannels (what could it possibly cause)?

To be honest I’m pretty confident that the solution could lie in min en max the settings for the fine movement. But I can’t seem to find a way to indeed set this for a specific channel only for the normal pan and tilt not the fine.

By making the movement window smaller I feel it won’t “overshoot” the normale movement in the step.

I now think the movement itself from the wolfmix is fine but the left to right range of movement of the fine channel in the fixture itself is to wide.

[axell]

i think you can not "degrade" the resolution between the coarse values, which is what you actually do by reducing the "steps" between 2 coarse values (8bit) when reducing the steps betwen them from 255 to 155.
When using Beam Editor, you can not reduce the micro steps alone, only the main pan and tilt (as the micro steps are not really a position but more the resolution between 2 positions.)

[Kevin88]

Changing the pan min & max is basically setting the range of movement indeed max left max right. Or up down for the Y axis.

To bad this isn’t possible for the fine. I really feel like that would be my solution here.

Especially since the movement of only the fine 0-255 is pretty big wich add to my conclusion it’s to much
