A lot of items only require the first word to be capitalized so instead of /equip oh "Garnet Grinding Wheel +3 it would be /equip oh "Garnet grinding wheel +3 There are exceptions to this rule and if your macro was working before they may have changed it for some reason, I saw another post that they changed the spelling of some items. The best thing to do is go into Gear in the main menu and manually equip your OH tool and then type it into the macro exactly how it is displayed in the chat log.
