Hey Sgian,
One more thing beside the good auggestions by Ken. Check the alignment of the jig - those two smaller knobs on the SG-77 are a bit touchy. There is a line on the side of the jig to aid in making sure the jig is straight. Also - on every chisel and plane blade I am sharpening I check the alignment of the tool to the jig with a small engineers square. When I first started sharpening with the Tormek I had exactly the problem you are describing, and it was driving me nuts. The slightest misalignment of the tool in the jig will create a problem.
I hope you get this "straightened out"!
Joe
