Spindle Problem?
I have a 12Z mill I bought from Aaron many years ago. I also got the CNC kit as well.
Within the past year I began to have a problem when I turned the motor on. If I have the speed set at 3 the spindle turns
at only about 40 rpm. I then gear down to 2 and it starts fine. I have to leave it running in 2 for 5-10 minutes before I can
switch it back to 3 and have it go to full rpm. I suspect I am having problems on the spindle bearings. Is this a reasonable
diagnosis?
