Hello again,

I have tried setting a fine value for 20-240 for example, but that just created awkward jumps (as expected).

I did do another experiment though:
- Made cuelist with two cues for different positions; P/T speed 100%
- Fade time 20s on each cue and loop mode => Jerkiness is there
- Fade time 0s; delay 20s; P/T Speed 1% => Heads move smoothly

The issue is 100% related to the controller side (or DMX?); when the heads are in control they move smoothly.
I have also disabled encoder feedback on the heads, but that made no difference.
Also, using a different interface has made no difference.

Hi again,

Could you elaborate on how to constrain the fine channel to 0-200; the DDF documentation says nothing about that being possible.

I would like to try that as a last resort.

Thank you for your answer.

Just to clarify:

1. Inverting Pan and Tilt is "bad", it can mess with slow movements

2. It has nothing to to with the interface or the way packets may be split up

That said, I had tried already moving the channels manually; moving the fine channel slowly back & forth from 0-255 results in a good movement of the head.
Moving the coarse channel also works ok but of course much more jerky due to the resolution.
Your idea is interesting; I understand you are saying the fine channel "overshoots" the coarse channel; how can I change from 255 to 0 and the coarse at the same time from, say 0 to 1 at the same time to observe this? If I keep the fine at 255 and move the coarse to 1, it will move the 1,255, which is of course in the same direction, but we want to test 0,255 to 1,0.
In either case, how can this be implemented in the DDF? Is there an undocumented parameter for the finedmxchannel that says range=224 or something? I suppose we should keep this a binary value?

It is also worth noting that this isn't completely random; certain segments of an ellipse are predictably bad and others predictably smoother. I other words, I believe to have observed the jerkiness to be deterministic. This is why I am suspecting a programming issue.

Fwiw I have also now purchased a USB to DMX to test another interface, and I have also tried Ethernet vs Wifi and wireless DMX vs cabled in all combinations, all with the same result.

Thank you Stefan; the first one disappeared so I thought I made a mistake posting and then posted it again :}

Hello again,

I have a question about effects.

If I apply a slow oval movement to moving heads (say 10* pan, 10* tilt, with a slow frequency of 0.05 or 0.03, the movement jitters. It either jitters forward, but quite repeatably also jumps back a bit and continues forward movement afterwards.
"Fast" movements are ok (or fast enough to not notice problems - Frequencies above 0.1-0.15 are fine.)

Overall it is terrible to watch and I would like to find a solution for this.

The moving heads are Eurolite TMH-S180 controlled through a Eurolite FreeDMX Pro512 via Artnet. I have tried Pan/Tilt Speed adjustments, but it does not appear to make a difference.

Here is a the pan/tilt section from the DDF:

    <position>
      <pan dmxchannel="0" finedmxchannel="13">
        <range range="540"/>
      </pan>
      <tilt dmxchannel="1" finedmxchannel="14">
        <range range="270"/>
      </tilt>
    </position>

I suspect either

a) DMX packages arrive out of order
b) The head positions itself between receiving coarse pan/tilt and fine pan/tilt (hence jumping around)

I am fairly new to DMX, so please forgive me if I miss some relevant information.

Please give me any advice on how to fix this; I would really like to make some slowly but smoothly moving scenes.

Hello DMXControl Experts,

I have the following Prism section in a DDF File:

   <prism dmxchannel="9">
     <prismrotation dmxchannel="10">
       <step type="stop" mindmx="0" maxdmx="63"/>
       <range type="cw" mindmx="128" maxdmx="191" minval="0.1" maxval="3.0"/>
       <range type="ccw" mindmx="64" maxdmx="127" minval="0.1" maxval="3.0"/>
     </prismrotation>
     <step type="open" mindmx="0" maxdmx="127" caption="Open"/>
     <step type="prism" mindmx="128" maxdmx="255" caption="3-facets radial prism"/>
   </prism>

However, I want to add a "Prism Rotation with Shake, Increasing" on channel 11 (DDF: 10) with values 192-255.
This range is on the <prismrotation> channel, but the <prismrotation> doesn't seem to support that, only "stop", "cw", and "ccw".
What would be your advice to get this shake to work?

Dear DMXControl Folks,

I have a small problem implementing a prism shake effect.

Here is the relevant DDF code:

    <prism dmxchannel="9">
     <prismrotation dmxchannel="10">
       <step type="stop" mindmx="0" maxdmx="63"/>
       <range type="cw" mindmx="128" maxdmx="191" minval="0.1" maxval="3.0"/>
       <range type="ccw" mindmx="127" maxdmx="64" minval="0.1" maxval="3.0"/>
     </prismrotation>
     <step type="open" mindmx="0" maxdmx="127" caption="Open"/>
     <step type="prism" mindmx="128" maxdmx="255" caption="3-facets radial prism"/>
   </prism>

I want to add the "rotating prism shake in both directions" functionality.
This is on DMXChannel 11 (so 10 in DDF), range 192-255.

I would need something like a third range handler, but I am unsuccessful with any syntax I try:

<range type="shake" mindmx="192" maxdmx="255" minval="0.1" maxval="3.0"/>

Any pointers in the correct direction would be appreciated!

Thanks for mentioning QLC EFX; I have also looked into that.
However, I really do prefer the DMXcontrol interface; the QLC just feels too tablet-like for me; I really don't like it much at all for anything other than the fact it has this feature :}
The DMXControl way of making things happen is much more intuitive and logical (at least to me), so I'm hoping this will be implemented in the future.
Unfortunately there is no core application source code on github to check the viability of submitting a patch :}

Thanks again; I will check back and see if this can be realized in the future!

Have a good Sunday!

Thank you for the quick answer and confirmation of the issue.

- Do you know of a workaround in the current version?

- Is there an RC version or Beta available for 3.3.2?

I really like the DMXControl the best from all I have seen, but am not sure how to realize and coordinated movement given the mountings of the heads.

Hello DMXControl users,

I have recently started playing with this software and find it amazing; I am very happy with it. I am new to lighting and have tried some other softwares also.

I did come across an issue though that may be a showstopper for me, and I imagine I am doing something wrong because the software is so well thought out.

Here is my scenario:

I have 4 moving heads, one in each corner of a room.
I would like to calibrate them to the floor, and create effects where they can move in sync. Essentially I want to map them to a coordinate system of the room.
They should be able to point to the same spot, and from there pan/tilt in sync across the floor. This would also facilitate fanning and effects.
Another software I tried was PC_DIMMER, and it had such a calibration feature in the device settings

How can I accomplish this in DMXControl 3?

Here two examples; all pointing and following the same spot on the floor with pan/tilt movement, and the second one where they are fanned and following a circular pattern, for example
