G33.1 synchronized tapping problem

Thanks for the troubleshooting suggestion.

Yes, same behavior, but much less Z-distance during the initial 'dive' than when using MDI.

Approximate position the Z-axis rapids to before synchronization while running a program:
G33.1 Z-0.5 K0.05 $0
(Starting at Z0.500")

• 60rpm: 0.440"
  • rapid dist: 0.060"
• 100rpm: 0.390"
  • rapid dist: 0.110"
• 200rpm: 0.370"
  • rapid dist: 0.130"
• 400rpm: 0.300"
  • rapid dist: 0.200"
• 750rpm: 0.140"
  • rapid dist: 0.360"
• 1000rpm: -0.125"
  • rapid dist: 0.625"

So perhaps 1/4 the distance vs MDI.

Still don't think this behavior is right.

Changing the Z-axis accel only slightly affected the rapid distance, if at all.

The earlier tests were done with MAX_VEL = 4, and MAX_ACCEL = 175.

Dropping down to MAX_ACCEL = 2 resulted in approximately the same pre-synch rapid distance at all speeds.

Much less violent rapids, of course.
