5 Axis CNC cutting where not suppsed.

[CvetanTokov]

Hello ,
i had build 5 axis cnc mill machine ,
i had problem with 5 axis simultaneous machining , it seems that one of rotational axes doesnt go with
desired feed rate and it is faster , so i left with cutted part every time in same possition.

In this picture you can see the cutted edge:

There is g code view:

The machine is build with external drivers , it is configureted and calibrated , i tried to implement bed compensation , but i didnt manage, and after this it start to make this cuttings, before it was perfect.
I tryed many diferent jerk policy and speeds but nothing helps.
I this it doesnt read go code good , and go beyond the points it supposed go be.
Any suggestions?

@cvetantokov
You have higher values for instantaneous speed change and acceleration, on the A and B axes, than X Y Z.

Try matching the other axes?
I don't know if that is the problem, but if A or B can change speed faster than the other axes I can imagine it causing mismatched movements on velocity changes.

It's a critical setting on industrial CNCs - the axes servo responses must all be matched or shapes can be cut incorrectly.

[CvetanTokov]

Yes i tryed it , the speeds are even, same problem . Now i will try with slow instantaneous speed changes - around 100 to see if there is any change.
I am not sure about kinematics, i rely on only the CAM software, should i change any kinematics setting on duet ?
This is the configuration of machine:
