Machine Jerk When Post process all command CAM

Hi
Now I use Linuxcnc V.2.9.4

I have a problem when Post G-code from Fusion360
If I post 1 post 1 command (Adaptive clearing) it's No jerk
but When I post  3 command in Gcode  
1. Adaptive clearing (tool 16)  Not jerk
2. Face  (tool 15)  Not jerk
3. Adaptive clearing (tool 16) Jerking

Step 3 my machine will jerk  when entering a curve and Velocity move slow down to 10-30 % feed , And will back to 100% speed when back to linear move .

My post I use
G64
G64 with P
G64 with PQ
Same problem can't solved .


 


I try
Post Gcode only Step 3. Adaptive clearing  it's not have a problem can run full speed and machine not jerk 

How I can fix this problem ?

Thank you
Asis

I Found a problem
If use FACE process
next step after FACE , not include G64 P Q Line
maybe problem from Post Processor of fusion360 

now my post $Revision: 44166 e813d608ccd22fb0949f73fcdb773b434407b131 $

I put G64 with PQ in  adaptive clearing step3 now can solved no machine jerky
Problem not from linuxcnc , problem from Post .

Thank you
Asis
