I have an SL 10. I'm programming a part that has an R8 shank taper near the chuck. I'm using MasterCam X4 to generate canned cycles for this. When the lathe starts the last rough pass, it starts tapering in towards the chuck and cutting the diameter smaller than it should. This is weel before it gets to the R8 taper which it seems to cut just fine. When I say it tapers, I mean it moves in X as it goes along the Z axis. I have run this same program in 2 HAAS simulators and neither sim will move in X when it's not supposed to. Here is my code. I have MasterCam set to put the tool nose offset in at the controller. This is posted for a generic 2 axis slant bed lathe, as I've not been able to get the HAAS post running yet. Does anyone see what could be causing the problem?
