Kinematics for 4th Axis?

As for the question of the 'zero point' moving
In TCP mode the point rotates with the part in Trivial mode it will not. To have the point rotate with the part but remain oriented on the machine axes would require custom code to translate the coordinates according to the rotation.
I'm not sure but 'Dynamic work offsets' or 'Dynamic Fixture offsets' may be of interest.

Hello Aceiera,

I'm also trying to achieve similar 4Axis TCP kinematics. I want to use Rotating spindle head and XZ gantry with fixed table. No B or C axis. I tried to compile 5Axiskins by removing C axis values but not accepting compilation. Any help would be appreciated.


Thanks

I would leave the kinematic as is and simply set the unused joint position to zero.

Can you throw some example? Zero in what?

I tried to compile this old working 4Axis kinematics (originally 5Axiskins) but getting compiling errors

Not able to understand current 5Axiskins
