On a previous post, someone had written about their machine with a thread cutter and difficulties with it cutting the threads too short. I have a Brother 6000D with a thread cutter and love it. The machine gives me the option of the length of cut which is awesome. I always leave it at the original setting of 0.5 but can change it if I want. While I don't remember what type machine the poster has, it is worth taking the time to explore the options and see if you too can change the length of the cut.
