I was playing around with the C Axis and the Custom Siemens Mill-Turn Post for Fusion and discovered a few things.
To make the post processor work in the posted code you must:
Remove all ref’s to SETMS
Remove G97 M2=xxxx
Remove any reference to “Y” axis
Remove “TRANSMIT” and “TRAFOOF”
In Fusion: Keep Smoothing ON and Tolerance Loose
I also deleted a lot of the C axis moves that weren't associated with another move, as the post seems to produce micro motion of the C axis.
I attached the code I am testing to produce the video.
Also I attached the post processor in case anyone wants to edit it.
Here is the C axis actually working:
I am not certain if the jerkiness is due to the programming (most likely).
