Feedback control XY not full speed run G1 when curve or Arc

Hi
I use servo motor 750W  and encoder from motor connect to 7i77  X and Y axis Feedback control
I use fusion360 for CAM and option G64 P0.002 Q0.002
when my cnc run process  Adaptive clearing toolpath is curve or  Arc  I few cnc base little jerky and feed in Gcode(G1) is 1200 mm/mins but CNC just run 100-300 mm/mins
How to fix this problem ?
I don't know where setting wrong.

Thank you
Asis

 
 
 

Hi, MR.ACIERA  MR. TOMMY

Thank you for reply and sorry in weekend slow reply. 
This below post file gcode problem.
example about in gcode file at N15 to N3900 


**Also, what acceleration is set in the ini file?**
Tomorow at workshop I will check and told again.

Thank you
Asis,

 
 

Hi Tommy
This is my ini file .

You should increase motion blending tolerance (g64 p0.002)

The more accurate the tolerance -> the lower the speed.

For roughing operation (adaptive) such accuracy is not required. Try setting P0.05, this will smooth the trajectory and allow it to be executed at high speed.
If the acceleration of your machine is not high, then for roughing operation you can choose P even more.

Traj section in the ini file, velocities are much lower than in the display section, try setting those same as display section.

Hi MR.Tommy
"much lower than in the display section" Okay, I got it wrong. I think it's for the motor velocity. I will change it back to default.

Thank you,
Asis

Hi MR.hmnijp 
Thank you for the suggestion. I have applied your advice and made some adjustments. Previously, it was G64 P0.002 Q0.002. Now, I’ve changed it to G64 P0.01 and removed the Q0.002 parameter. The machine runs much more smoothly, although there are still some slight jerks when transitioning into curves during G0 moves. However, it’s a significant improvement.

Do you happen to know what the Q parameter is used for?

Thank you,
Asis
