like said above dull tool to fast of feed...also did you check the table? see if there is movement from wear...? most people use them close to chuck so try moving it up down side to side close, then again far out from chuck probly really tight out there......? is it bushing or ball barring shafts? bushing over time wear also....check everything. is it brand new? or just new to you?
just throwing ideas out to you what other stuff that could be throwing it off.
