When trying to generate Gerbers output, I get an error message 'File buffer is not initialized' and the Gerbers file is not being generated.
Solution Details
When generating a Gerber output, users may receive this error:
This issue occurs when the Filepath name is too long. To resolve, check the File Name and the overall path character limits. Select the Change button for the Output Container used by the Output. Edit the Setup Locations to lower the character count, to make the Filepath name shorter.
The best method to lower the character count is to change the [Output Name].
