0I recently installed the rotary accessery tool and my RA2 Pro rotary tool. It worked great and I was able to etch several wine glasses with it I disconnected it and did some wood engraving. When I reinstalled the rotary tool it would no longer work properly, When I tried to frame a project it made a grinding noise and did not frame it properly. If I try to etch the project it does not turn the glass properly and makes the same grinding noise. Help. I have orders for wine glasses that need to be filled.
