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.

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.
