I am in the middle of a project, I hear the machine stop, simultaneously my heart stops. You know the feeling. I get a message " check cut motor ". Oh no now what, I am thinking. I have an option to PRESS ENTER TO PROCEED. After sniffing around to see if I smelled anything burning I press enter. The machine continues where it left off. Seems fine. No odd noise anywhere, the spindle is cool almost no heat. Is this just something CW does for no apparent reason or should I really be concerned. Do I need to keep spare parts although I have a 2 year warranty or about 150 hours. Any probable cause or a fluke.
