Must be related to Alien then!!!!Mrboots2u said:Or has spilt it on the burrs
I’m not sure which precise bit you’re referring to. There may be some shadow in the photo or a coffee granule but there are zero marks on the outer rim of the lower burr (which would correspond with the damage on the upper). There are some tiny marks around the breakers away from the rim, but they seem to be natural imperfections in the casting.Top left of the lower burr looks marked in the pic.
Have you took it out to look
