As long as the 5 axis toolpath is short straight lines mach3 can process poor man's kinematic motion with tool length compensation, even compensation for bad rotary head alignments, provided some vector formulas are inputed, the downside is no true jogging. Unless you use mdi, what would be good is a step based mdi jogging routine(10mm at a time?), i ll look into this when i get some free time and its raining.....
Piv, i never noticed mastercam having kinematic computed outputs, where are the head values set? I assume It wont do kinematics for heads with b and c offsets like CNC toolkit? ...or did you mean 'cant' rather than 'can' in the last post.
I really do like toolkit...
I still swear by indexed head machining for big curved open surfaces on routers...it's like overdirve on the autobahn compared to 2nd gear round the back streets.
