Is there a way to create a custom parameter in the fixture editor?

I guess the answer is "No!"

Political correct answer ro custom parameters is No.
Don't try it, it is not comfortable.

With the different DMX adresses in one parameter... i think i saw it once in a fixture.
I will try to remember.

As I suspected.

All I want to do is to create parameter names "Forward", "Backwards", "F.Speed" and "B.Speed".

I can already do the non-intens parameters using the DMX values ranges.

For the Speed, you can use "Global MSpeed" & "Global MSpeed2" in >Form< Or if possible only use one and have them set to +/-

And for the direction...

All different.
You have a "Master" of Forward or Backwards.
If you go Forward, than only the Forward speed (parameter Global MSpeed for example) will increase in positive direction.
If Backwards is selected, the parameter will set up the other value to 0 and move the negative speed (Backward) up.

You likely will go with some virtual parameters.
For Motor-direction you could use "Effect Direction" as a virtual parameter.

Let me wrap my head around that... 

Hey jamiej  just for me. What is the Product name and the company that made this product?
Want to have a look in the Manual.

Hello Mathilda - you're always so helpful here!

You've put your finger on the problem! The snow machine was built in our workshop by another tech. I'm trying to create a personality for it on our Ion.

I'm pretty much there in terms of what DMX values need to be for its limited functions and I have a draft profile made but I really want to make the device have cosmetically meaningful control parameters when someone else is using the board. I know what the device can do and how to control it but my colleagues mostly do not and others will come after me.

I've looked through all the built in parameter names in the fixture editor but didn't find anything I could substitute for what I really wanted.

You've already made a couple of suggestions above and I'll look for those. Wouldn't it be great if we could create our own parameter "labels" in EOS? I don't suppose it would be used that often but it would be super.

Yeeees, there is a feature request somewhere for creating your own parameter labels.
And i love to have that as well, since we need sometimes fancy names on the parameter.

But who knows what the future will bring us. In the Future there should be some other option for sharing Fixture-Profiles. I have been told. So, let us look forward to that.

And i figured something like a custom build product.
So, yes we need to do some magic.

Is the Motor-direction something that could be done with 'Lamp-controll' ?
It is not on an encoder that way, but could help maybe.

I've come to the same conclusion.

I'll put direction controls in "Lamp Control"

And motor speed as an intensity value for encoders.

I'm not sure how I can align the motor direction to the motor speed control so that selecting "Forward" and then adjusting the "Backwards Speed" intensity would not send any DMX values (such a setting makes no sense anyway - I'd have built the electronics that responds to the DMX values differently!) I've yet to try my profile with the device so not sure what it will do when told to run forwards and then it gets a backwards intensity value. Hopeful not fly apart into a snowfall of a thousand cogs, nuts and springs.

So the bigger problem i see is the Fixture in the real world.
If somehow the Motor Direction could be only one DMX Parameter, than it would make our ETC Fixture much more easyer to built... Hmmm.

Any way that could be achieved? 

I think i have a break trough.
A bit around some more corners... But maybe the best i can think of right now.

I quick-checked in Offline with the sACN view.

How it works:
1. There is a dummy channel on DMX 5 for the direction of the Motor
2. The Dummy 1 and Dummy 2 are helpers for switching the Motor Speed for the relative direction
3. Global MSpeed is for Forward-speed and Global MSpeed is for Backward-speed

Hench, you still need to switch between Forward/Backward as a Mode
Have a test with it and tell me what you think.

Forgot... I think a 'Snap' on "Effect Direction", "Dummy", "Dummy 2" could be helpful.

Gosh Thilda - you're marvellous!

That profile is far more sophisticated than my puny attempt.

As soon as my colleague can sort out a time to test his creation I'll let you know how it goes.

Many, many thanks!

Jamie

My pleasure.
Thanks for this wonderfull Task. I enjoyed it very much.
Hope it works out as you hope.

Have a wonderfull Weekend, i will treat myself with some ice cream now :D

that's how i do the locking against each other. it's similar to what thilda did, but i use three ranges, the third one for stop.

i really recommend combining this this custom encoder mapping. don't map the actual parameters (in my case Move_Up and Move_Down) but only map Effect_Direction, it's the only parameter you need and like this you avoid that somebody manipulates one direction without locking out the other. of course you would need to consider the speed parameters as well.

Only one or the other 2025-08-16 19-43-56.esf2
