first of all, try to ground to the metallic structure, not only the "ground" of the canbus, that wire may get damaged, but this would be difficult in a voron i guess. this shit is way easier when there is no plastic parts linking metal parts.
i mean where i work every machine takes extra care to have all its parts grounded...
the extruder and bed heaters should be grounded in case there is a short. but instead the 3d collective decided that the best option was not use mains, but use low voltage (so you need to add a big power supply just to burn it in a resistance), as if that would made it safe enough
i mean without grounding im 99% sure it doesnt comply with the eu regulation of machinery... but i also know that 3d printer companies try to argue that 3d printers are printers and therefore office appliances and not machinery to avoid this, last time i checked, like a couple years ago, the commission were supposed to make a clarification on that but shit is slow

i would try to insert a connector inside the 3d print somewhere, or ideally use lugs like picrel as a washer wherever screws or nuts are used
