 +== Lathe G112 face interpolation mode ==
 +\\
 +
 +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.
