Having issues with quality of cut

Hi folka, I’m new to to the CNC environment and seem to be having some issues when I’m running a surfacing job with my Longmill 30 x 30 using Gsender the quality of cut seems to be uneven . It looks like the bit face is not running true to the spoilboard. I’ve checked that all the setting on the machine are true and level, the router is square to the spoilboard. has anyone run into this issue or have any suggestions? Thanks Alex
