Thanks Dave, Andy, Slavko for the input I took a look at the code generation and right before tapping starts it issues a G61.1 to force the tapper to stop at the correct positions at the end of the centering tap. It looks like if I split the Y motion into 4 segments, actually 8 segments, since I would need a tap followed by a retract of the tapper, the Y axis would start and stop 8 times. The acceleration is horribly slow on the Y axis since the gantry has a lot of mass, so it looks like this almost worked except for the G61.1.
I did not think to try to operate the stepgen without the trajectory planner. I will look into this. I hope the stepgen can handle it's own acceleration and deceleration without the trajectory planner guiding it, but only way to find out is to try it.
