Hi All!

I am wondering if anyone else is running into / solved an issue with fusion 360 requiring a number to start the file name for the export?

In the above image of the post export, I have a name of slot\_workDrawer, which comes with this error on _post_

this is the error I get requiring a number.

It does export with any number as the prefix. But that has already gotten annoying trying to keep any order to my gcode folder.

Anyone run into this or know what could be going on? A google search just comes up with “put a number in front for this issue.”

Try naming your file 1001 1002, etc. That should work. This is an odd bug that’s already been patched. I’m just waiting for Autodesk to update the post on their side.

Thanks for the very fast response, Eric!

Glad a fix is already in the pipeline.
