Zoho ticket #24002 see 6/29/2023 response to client:

The coords are not output Polar, just C Axis. The generic post functions fine.
Thankfully, it is actually polar, it's just the C outputs are the Y positions.
The post has this toggle because frequently, machine's need a C in front of the Y-axis polar positions, and on other machines as you mentioned, Y is required.
\\

''g112address   : 1    #0 = Y, 1 = C''\\

\\
So I have just switched this toggle and tested and I am returning a new PST/PSB to you with the Y label on all the Y polar positions.


Please also note, if the rotary axis control setting in the toolpath is set to "no rotation" or "Y-axis" the post will respect this selection and initially position in XY, rather than XC, which I believe is not what you want, since the Y will not be at Y0:

\\
<code>
G98 M134 P1000
M154
G0 C0. Y0.
G0 X1.4142 Y-.25 Z.25
G112
</code>
\\

It's important to set the rotary axis control to C-axis, since for polar, you're only using XCZ in reality:

\\
<code>
G98 M134 P1000
M154
G0 C0. Y0.
G0 X1.5 Y0. Z.25
G112
</code>
\\

The above wouldn't matter if your machine didn't have an actual Y-axis. In that case the post would force XC always regardless of the setting.
