Afternoon I'm new to this so I read all the post learning things. I have a question about your setup. Your wiring, I understand keeping the data seperate from the power but is it helpful to run a ground with your data lines. With data is it better to run bigger gauge wire, or does it hurt.
I run 18 gauge 2 conductor wire everywhere. Yes, for my setup, it is important to run ground with data to ensure grounds across different devices (controller, powers supplies, Raspberry Pis, everything) are all grounded together.
For example if I only ran data from my F16v2 in the entry way up to the roof, and then my snowflake arches get power from a power supply on the roof - the grounds between the two systems wouldn't be connected which is a big no, no as I understand it. So yes, I run negative with data along with running negative with data. Again, all 2 conductor 18 gauge wire everywhere (allows me to buy in bulk by not using different gauges).
