After about 5 minutes of actual use, the saw developed a really loud grinding noise. Made all the obvious checks, then took off the belt to try and isolate where the noise was coming from. Turned the saw back on and still had the same noise, so definitely coming from the motor. Sounds like a bad bearing. Returning tonight back to Home Depot to exchange. Really looking forward to putting it together for a 2nd time and dialing in the alignment...sigh. Sound clip attached.
