Graphtec FC8600 cutting round corners

[sc12345]

Hey Folks,
Would you be able to tell me what I should do. I noticed the cutter shakes while it cuts round corners. What should I do? Please help.

Make sure your blade holder is not packed with gunk at the tip where the blade extrudes from.

no gunk no nothing. is there something i have to adjust on the settings?

Make sure the blade holder is tight. Does it cut a clean circle or is it more of an octagon? If it is the octagon the whole carriage is loose. Its an easy fix but will take a little time and effort.
