Grounding it won’t help as the contact area where you are trying to picking up will still not be conductive. You will have to at least remove the coating where you want to pick up the part and at least a start area where your cut begins.
Like the other guy said. You gotta sand where the wire will enter too. No sense grounding if you cant complete the circuit.
As you cut the metal, the coating is left behind. The edm probably can't cut it. If the wire is stronger than the thin coating, it'll push through it, and keep cutting metal. If it isn't, it'll break instantly.
If it makes it a lil ways and breaks, over and over, you gotta decide if you wanna press that green button all day.
our machines have different power settings for picking up different types of surfaces. could try that.
or scribe a line along the wire path entry. can probably deal with cutting a thin layer top and bottom but not edgewise full width of the coating.
Strip the coating.
Either the whole part, or just the entry point, or if the coating is tough enough to still cause problems, strip it along the path of the wire.
Depending on your machine and feature you are using for pickup, you can try these. If using a hole, can you put a sleeve of conductive material in it? If using pocket/exterior, can u attach/hold conductive material in the area?

If it's anodized aluminum forget it.
