In other threads related to C or Y axis output, some posters altered post to change X0 to something like

X-1. which prevents post from triggering polar mode when tool crosses X0.

Since there is some usable stroke below spindle centerline that varies by make and model, this can be alternative solution for small parts within machine's range.

 

The question I have is, since polar mode relies on rotating C axis around X0, what happens when you use up your Y axis stroke and only option left is polar mode ?, my guess is failed tool path.

 

When features are symmetrical, by original design or by intended selection, forcing Y axis output is possible by programming only features above X0, then using circular pattern to rotate C axis and complete rest of the work, just wanted to throw that out there.
