While doing a little turning today I noticed when I turned the speed control knob "on" I get no response until I turn it at least 1/3 of the way up and the the spindle begins to turn, but the lowest speed I can set it at is about 400 rpm. I've done some reading, and it appears to be a potentiometer meter issue. That seems to be a somewhat common issue with the G0766. It's a little frustrating since the lathe is only about 6 months old. Is there anything that I should try before calling Grizzly? BTW, I'm not an electrical engineer, so please don't get technical.
