Moving head goes crazy

[myknack]

Hi guys,

I am trying to get my QLC+ working on the RaspberryPie. My problem is, that my moving heads doing weird things. E.g. I turn brightness and red on 255 which should be a continuously red light - instead I get red with irregular flashes. If I try pan movement then the movement jerks .... etc.

If I am using the same setup on my Mac then everything works fine. What is wrong with my raspberry setup? Any tipps?

I am using:
RaspberryPie 3
QLC+ Version: qlcplus_raspbian_stretch_20181110
JMS USB2DMX® OPTO
2x NoName Moving Heads (I added the fixtures manually).

Looking forward to get any feedback.

Cheers,
Daniel

Please try to adjust the output frequency to a value between 30 and 40 Hz.

Thanks .... I could change the frequency not in the web interface ... but inside the desktop app it was possible. It seems, that it works! Thanks!!!
