Yes, i think by "cable cross-talk", per se i might understand something bit different, basically for me that means the wires inside the cable interfere with each other. We would need a freqency first for that to happen, and some more signals than just one. This is what i tried to make explicit that i dont think it is the case.
For the other kind of interference, the emitters are the pid heaters, stepper motors and cables, and it could be the mains wires themselves if the psu consumes enough. The "antenna" would be the signal wires. Tho idd the "antenna" thingy is not a proper comparison from my part.
To be fair the most susceptible part i would expect to be the thermistor signal, because that has a resistance to its end, but again it has that cap which can work a little. While the endstop in comparison if its wired correctly, it makes a short to ground and that makes the signal also gnd for the time endstop is not triggered, and then that signal line is not "moveable". So the "antenna" comparison doesnt work well in that case. But if the endstop is set its set up the other way, like with the signal wire floating for normal un-triggered, then the endstop signal like would be a lot like a real antenna. So who has endstop problems, it could be because it has them set up for 5v = normal (un-triggered)? Coz else i dont see an interference to raise local gnd with like 4v.
