    Default projector grounding

    have I read correctly that all ground cables should be connected together in a laser projector, including the ilda GND pin, signal GND cables AND GND from PSUs?

    no. don't tie the DC signal grounds to the AC grounds.
    suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.

    Sometimes it's unavoidable tieing AC and DC grounds due to the way some PSU ground DC to chassis

    You are using Bonetti's defense against me, ah?

    I thought it fitting, considering the rocky terrain.

    I think ILDA published an article written by Bill B. from Pangolin years back. The article might be on the ILDA website.

    You might be thinking of this: http://www.pangolin.com/resguide12.htm

    Here's also a video demonstrating what can go wrong by connecting all grounds together: https://www.youtube.com/watch?v=Vm0GISQi9fE
