hiiiiii everyone!

i'm fairly new to this, so I'm sure there's something simple im doing wrong, but all of my cuts on my 770 are off-center in X by about 0.2". i'm using a passive probe to set my work origin in the corner, and i believe i have my origin set correctly in fusion, using model box point. the fusion simulation looks correct, but when I begin my operation (say a contour), the bit will take a normal cut on the left side of the stock and then run in the air on the right side of the stock. i've tried to troubleshoot this the best i can, but i can't seem to figure out what this issue is. has anyone run into an issue like this before?
