Action - Force XYZ Mode?
I recently noticed the Action command, specifically the useXZCMode and usePolarMode. These both seem to have the same output (XZC coordinates). Is there a code module that could be added for useXYZMode to force a Y axis move instead of a C axis rotation?
Sometimes the code will post with XYZ and sometimes its XZC, and I am not sure what the deciding factor is.
Specific post I am using is Doosan mill-turn fanuc.

There is no such command as useXYZMode, if machine has Y axis, you are using XYZ mode by default in any work with radial tool orientation and G19 plane (YZ)
"useXCZmode" can only be done in G17 plane (XY), tool set in axial direction and working above spindle center line.

How about axial tool orientation? That seems to default to C rotation even when the work would fit in the Y envelope

I explained that in my last post, at the bottom.

I see it in the link - the deciding factor is if the tool crosses the centerline. Good to know in case I want to program around it.
Still would be nice to have a force Y option, machine has plenty of Y travel.

Some people altered X axis range in post to use up whatever stroke machine has below center line and by doing so avoid use of polar mode.
You have to be careful with that because once you use up Y axis stroke, only other option is polar mode and that uses X0 as center of C axis rotation, so if that value is modified in post, I would expect things to not work as intended with resulting code.
My take on it is, .... just learn how things work and use right methods to accomplish desired result ,..... "force" one thing or another by design and not by chance.

The Manual NC command type I was referencing was Action, not PassThrough.
