Hey guys, Bought an X01 last year and just changed the grinding wheel for the first time today. Original wheel was orange and the other wheel that came with the purchase was ruby. So anyway, I put the ruby wheel on today and attempted to sharpen a set of skates....and let's just say, it didn't go too well. With barely any pressure on the skate, sparks were flying and a loud grinding noise took over. I shut off the machine quickly to reveal the following: As you can see, the skate sharpened the wheel instead of the other way around. The wheel now has a deep indent in it and the skate blade is rounded the wrong way. Has anyone had this happen before? Could it be a wheel gone bad (i.e. too soft)? Will be calling BlackStone tomorrow, but figured I'd post here tonight to see if anyone has any suggestions. Thanks!
