I had an incident recently where my front side carving didn't register with the back. I see in the manual where there is supposed to be an O-ring on the board postion roller, but I don't see one on my machine. Where exactly on the roller is it supposed to be? Could it have skipped off the roller and be riding around the axle, because I so see something rubber there, but it seems too small. I didn't try pushing it off and back around the brass roller. Is that how it goes?
Thanks
