I pulled the 12 inch 3 jaw chuck off of my used (newly acquired) 2011 Romi c420 lathe. The chuck was removed for cleaning and inspection. The machine functioned perfectly prior to removal (which was fairly ez). I set the lathe to manual mode with a spindle speed of 20 rpm. When I power up the spindle it doesn't rotate normally. It seem to vibrate. What could be causing this, PID? This machine has a 802 Siemens control.
