Fusion does have a habit of updating the posts on occasion and if you don't make sure to keep a specific one selected then you can run into problems. You might try a G63 (I think) is tapping mode, before the tapping cycle. Its modal, so make sure to switch back. It overrides feed and speed during the tapping cycle to make sure its at 100%. Also might check ipr vs ipm. I think that one is modal also. I'll try to look at a known good program of mine tomorrow evening and post up the code if you haven't gotten it working by then.
