Hi Jeremy,

Thanks so much for the prompt reply. I must admit I knew about the post not being 100% correct but everytime I try to use the later 'black' S4C post the following error is thrown -

未能使用Post P生成项目“主要”rocessor "ABB_RAPID_S4C"
Post processor path:/Applications/RoboDK.app/Contents/Posts/ABB_RAPID_S4C.py
2020-04-22 13:48:31.880 Python[24423:1115105] WARNING: found it necessary to prepare implicitly; please prepare panels using NSSavePanel rather than NSApplication or NSWindow.

Python Post Processor process exit code: 0

Which is why I have always used the legacy post. Maybe you could suggest why the above error is thrown?

I'm going to try what you have suggested on the arc issue and will report back. That particular section of code is based on a spline so suspect there are some tiny arcs in there.

All help as always very much appreciated!

All the best,

James

PS - My hair is saying thanks too.
