From the pic, it looks like you plunged directly into the stock or did it do a helix down? If you plunged then that would be an issue, not the best way to engage a cutter into material. When I cut at new speeds I turn the feed down to 10% and then ramp up once I have done the helix down and then started to make the cuts I expect. Sound / vibration / noise is key.
