G33.1 synchronized tapping problem

I have found a workaround for the issue described above using hal commands.
Here is my config including the hal component I use to disconnect the encoder position value and the modified orient component to rehome to index before orienting the spindle:

Some notes:
- Rotary (Caxis) is on Joint 4, uses a stepgen with settings from ini [JOINT_4] section
- Spindle also uses stepgen but with setting from ini [SPINDLE_0]
- Startup mode is rotary with joint.4 homing to index (ie joint.4.index-enable is connected in HAL)
- 'M419' moves rotary to 0 position, sets hal pin to freeze joint.4.pos-fb  and calls M119 to set stepgen values as set in  ini [SPINDLE_0] and disconnect 'joint.4.index-enable' to avoid breaking sinchronized motion as outlined in my last post
- 'M420' orients the spindle to 0° (using index to rehome first) sets hal pin to reconnect the encder to joint.4.pos-fb  and calls M120 to set stepgen values as set in  ini [JOINT_4] and reconnect the 'joint.4.index-enable' pin

Thanks cakeslob, i put back in the filter gain. when I monitor Spindle.0.speed-in, it also dips in speed. Even with the spindle off its still moving.
G-code G96  D1500 s200 M3 sets it 1500rpm suface speed 200. When you move X in and out the spindle should adjust.

Ah yes I have noticed those. Seems to me that it does not occur for fillets in the XY plane.
[edit]
which makes me think, are you still transforming the space corner to the XY plane to fit the clothoid as in the paper or are you skipping that step (as I believe you wanted to at some point). If you are fitting directly in 3d than that may have something to do with it.
