Hi Bob,

Thanks for getting touch. For the extension issue, you should check your SETUP.DAT file in your FastCAM Folder. Look for the "EXTENSION,XXX" line in file, and edit the extension to match what you need for your controller, E.g.

to get NC extensions, make it:

EXTENSION,NC

To get CNC extensions, make it:

EXTENSION,CNC

Also you may find the FastCAM Information starter pack useful:

In particular the part closure guide here:

As for the G41/G42 errors, that is KERF compensation error on line 54 of your code. So your controller is unable to cope with the Kerf adjustment required by that line. Usually this is caused by a really tight movement, or an angled movement that Kerf Compensation cannot implement.

You can try and figure out exactly where this motion is, and try to flatten it out, or you can try and use the Kerf Compensation that is in FastCAM instead. Here is a guide on how to use that:
