My SB has stopped cutting round circles. They are elongated in the X direction. See attached photo20170901_161101.jpg
I've checked:
. New collet & nut
. new 1/8" bit
. router securely mounted
. cleaned rails and re-lubed the rack
. checked X and Y pinion gears, secure and no wear or missing teeth
. Z axis checked at 90 from X car
. properly cuts squares
. problem is not specific to an area of the table
Thanks for any ideas,
John
