I'm was cutting mortises for cabinet door frames when I notice that the slots created by my domino xl are not very parallel to the face of my stock. Long story short, the flip down plate when set at 90deg to the cutter face is not really square. This results in inaccurate cuts no matter how careful I am in holding the tool in position. It is set with a ball bearing into a detent on the slide mechinism. There seems to be no adjustment for squaring the flip plate to the cutter face. I'm hoping someone out there might be able to help. Thanks for reading this post.
