How to check travel limits using machine-sim for a machine with parallel kinematics?

Hi,
I am programming with 90deg head angular head for Starrag 6-axis machine with 3 linear in head + 1 rotary C and 2 linear X and Y axes.

Here is the link to this machine info. https://www.starrag.com/en-us/machine/ecospeed-f-20602560/134

It has one optional rotary in the head and three parallel linear slides Z1, Z2, Z3 tricept fork like configuration to perform all required multi-axis motion including Z-axis.

I would like to check my toolpath’s travel limits for the joints(especially for Z1,Z2,Z3) in all cases including when 90deg milling-head is loaded for the toolpath. Currently I am using R28 at my work.

Thanks,
Samarinder
