Puma 5100XLMB gets PS0021 Illegal plane select when polar milling

I am programming for a new Puma 5100XLMB. It has live tooling and a C axis, but no Y axis. I am trying to polar mill a spline with G12.1, which I think the machine should be capable of doing. For some reason, about six lines into the milling code, it gives us a PS0021 Illegal plane select error.
I could understand if it wouldn't read anything, but it gets a ways into the code before it gives us a problem.

It will run to this line

?We also tried this format, and it ran to the highlighted line before giving us the error.

I don't think the machine can do what you want it to without a Y axis.
Polar interp is for the milling of non round shapes on the front (snout) of a part.
It has limited value elsewhere.

I don't think cutter comp can be applied to C axis
Only works on axes defined with G17(XY)/G18(XZ)/G19(YZ)

Try it by removing the G42

Has the machine got Helical Interpolation Option from Fanuc A02B-0339-J819 ?

About 6 lines into the milling the Z Axis comes into play ?

Without Helical Interpolation option PS 0021 alarm will occur

Helical is standard from Doosan, but the Polar isn't made for that.

Doosan supply as standard on Y Axis lathes but it isn't standard in the UK on M Models . It's either specified on order or a Fanuc retrofit.

I do not see a plane called out in your code. Try adding a G17 to line G40G80G99.
