You sound just like me. I have always wanted a Tormek and when the T3 came out I saw my opportunity and got it for Christmas. Unfortunately I think Tormek did a disservice to themselves producing this machine. I had the same problem you described while I was sharpening some of my cheaper chisels. Nothing was coming out square no matter how careful I was with the setup. I checked the support for strait, the stone and shaft for true and square and runout. I checked my chisles for flat and parallel, all were good. The problem I found is in the holes that the Universal support go into, specifically the verticle mount holes. I believe that the tolerances are too sloppy to allow the support to slide up and down and remain parallel with the stone which is necessary to achieve a square edge. I continued to use the tool but now I set my angle then tighten the lock nut closest to the stone then I press down on the outside end of the support just enough to take the slop out and tighten the second nut. This procedure seems to work as now i am sharpening much closer to square but I am hesitant to put my good plane blades on the machine. Maybe I'll keep hand sharpening them until I can afford a T7. Until then I will continue to use it for all but the most important stuff. I hope Tormek comes up with a fix for this before people start judging them on this machine.
