You misunderstand how G43/G43.1 work. They do not work differently for multiaxis machines. The tool table works as usual with G43 H_. G43.1 lets you specify the length directly in the gcode (G43.1 K___) and it sounds like you will not use this. The actual difference with the 5 axis kinematics machine is that you should specify [TRAJ]TLO_IS_ALONG_W=1. Then when you use G43 H_ or G43.1 K___, the length offset, no matter whether it comes from the tool table (G43) or gcode (G43.1), is applied to the W axis. The only thing your cam needs to do is move the W axis (G0 W0) so the length offset gets applied.
