I need 5 axis post for INVENTOR , there is one official post on Autodesk for Linuxcnc and inside is mention something like 5 axis simultaneous but i get error every time i want to build code '' Error: Invalid machine configuration in toolpath''. This post is working fine with 3 axis.
Did someone try this processor for 5 axis, or someone can check the file ( post processor) if it has capabilities to process 5 axis simultaneous.

Thank you for this information, maybe this error is some type of bug.
Still it will be good to now if someone used this post for 5 axis simultaneous moving.
Thank you

I have used it not for 5, but for 4 axis so I think I have come across most problems.

The post processor needs to be configured for your machine setup, how your axis are oriented.
There are five lines around line 193 that needs to be modified.

I would, a bit boring, say that the best is to search the autodesk forums for the general setup, there is plenty of info.
knowledge.autodesk.com/support/fusion-36...r-5-axis-motion.html

The axis is one thing, the three first lines.,
TCP mode is the other thing you need to set. If you use a 5-axis kinematics you set
optimizeMachineAngles2(0); // TCP enabled
if you use trivkins with two independent axis you set that to "1" and then you start wonder why the
feed speed isn't right.

I found this post working only on Fusion 360 and generates 5-axis G-code with software enabled TCP capabilities

Thank you

I am not sure how helpful they are, but PocketNC sell their machine packaged with LinuxCNC and Fusion360, so presumably they have a working post.
