hello guys,
i am want to implement 5 axis milling cnc machine kinematics with my own DH parameters, i have XYZAB joints , 3 linear and 2 rotational, is genserkins suitable for my machine config or is there is another kinematics model for this kind of config.

'genserkins' does not support linear axes.

do you propose another model that supports dh parameter?

i checked this doc, i want to use dh parameter rather than using mathematical equations for simplicity

unfortunately, i don't know any other kinematics for this, but i should also start working on this topic, maybe it can be extended by the parameters

I'm not aware of any other kinematic that would work out of the box.
This is from a comment in 'genserkins.c':
So for your purpose you would need to implement these two TODO points.
Note that 'genserkins' uses 'modified' DH parameters as also pointed out in the comments in 'genserkins.c'
This is from a comment in 'genserkins.c':
The parameters for the manipulator are defined by hal pins.
Currently the type of the joints is hardcoded to ANGULAR, although
the kins support both ANGULAR and LINEAR axes.
TODO:
* make number of joints a loadtime parameter
* add HAL pins for all settable parameters, including joint type: ANGULAR / LINEAR
So for your purpose you would need to implement these two TODO points.
