I was having a simular issue with my Kapex. Allen K was at my home and I told him about it. He took a straight edge and found the fence wasnt square. Where the spilt is in the fence where the blade cuts the material it was aligned where that area of the fence went towards the back of the kapex. He told me its a common problem. All he did was put the sraight edge against the fence and loosened the fence bolts on the back side of the fence. Mind you I said loosen, not remove,
just enough to where you canrealign the fence.
If I remember correctly mine was under tension and it just popped back into alignment.
hope this helps
