NC code failed to post "Error: Failed to invoke function 'onOpen'."



I have attached my file.


I am trying to post process for my fourth axis Stepcraft, but I keeps getting this error:

Hi @kksAZZV7 


Can you share the post processor you are using?

It's a file with the cps extension.

Because, apparently the post is either corrupted, or something is wrong inside.

Posting always start by calling the onOpen function.

Hello Serge


I think I solved it. I had turned aircooling on by accident which is not supported by Stepcraft. At the same time the cylinder inside the object was (maybe) not cylindrical after all. Anyway. It works now. Thanks.
