Please don’t take this the wrong way, I am not being picky just making a few suggestions regarding your wiring based on what I would try…
The inputs wiring (Estop, switches etc.) needs to be shielded right up to the BoB then the shield taken to the single point Earth. The switch ends of these cables need to be shielded close up to the switch but the shield left unconnected.
Earthing to various points on the metal backing plate is not a good idea – Earth to the single point only.
It looks like you are running a.c. wiring together with your TTL level signal wires – not a good idea.
Move the UC100 away from your a.c. wiring and perhaps connect it direct to the BoB without that extension cable.
Tweakie.
