This UR5e spare kit hasn't reached dispatch, unlike the adapter delivery I had to locate. Installed cable is present. Seller keeps offering space in a future shipment instead of supplying the extra.
Ask for a separate supply proposal with the cable identified, or a specific credit offer. Your shortage should not depend on an unrelated shipment appearing.
Asked for those alternatives. Seller repeated next shipment without answering either. I've left the spare marked unavailable for maintenance; not borrowing the installed cable to improve the inventory
