What’s Causing These Marks

[routerdriver]

I'd like to see a plan view image.My initial suspicion is either a tool length discrepancy or a slight tramming runout.It seems a bit odd that the spacing of the marks looks quite evenly spaced as the cut proceeds down.The suggestion to leave a little material for a finishing pass may well be enough to eliminate the problem.

Thank you. I’ll have another look at it. It’s a pain. It doesn’t look much but it means I need to do a lot of sanding and it didn’t happen before. Thanks for your help.
