Heidenhain TNC145 Fusion 360 Post, Incorrect End of Circle

[gta18]

Hi,

Trying out post processing in Fusion360 for my Bridgeport R2C3 with TNC145 controller. I drew up an Octagon as a contour test.

Fusion360 spits out a gcode with c and cc code. And after uploading and trying to run it on my machine, it gives me an Incorrect End of circle error.

I'm attaching my post processor, f360 dwg file and the gcode result.

Can someone familiar with this setup please advise? I really don't want to rip out the electronics and upgrade it as of yet.
