The simplest way to check if this is the cause is to manually jog the Z axis as far as it needs to go for the tapping sequence. if you cannot jog it that far in -Z, then you have hit the Z minus soft limit. As Gene mentions, apparently on at least some versions, the spindle synched motions don't CHECK for travel limits before performing the move. It could check for soft limits for the programmed Z move, but can't know how far past that Z depth it will go while the spindle decelerates.
And, if you are not using homing with home switches, Dave, you might want to set this up and enter the actual limits of the machine.
