Couple of things I see.!!

Dump the daisy chaining it's bad news.

I see several shields going to chocolate block but don't see anything leaving it or going to ground.?

Coming from the torch I see thinner wire that looks like it runs and is taped to the same wire has the limit switch.? If so then try separating has noise could be travelling from torch to switch.!!

If that mass of wires hanging on wall are stepper cables or signal cables then shift them away from those power sockets.

Generally check and tidy up the wiring connections, all those straggler wire ends are potential aerials either fit ferrules or tin the wires. Again Separate the power and signal cables.
