I have cut this file multiple times yet now my glowforge is saying the file needs to be closed or filled…
Welcome to the forum.
The message is probably that you have a clip path or an open path. You can try opening the file in your graphics program and trying to identify the problem, or you can try uploading the file again.
It’s been a little while since I’ve seen any replies on this thread so I’m going to close it. If you still need help with this please either start a new thread or email firstname.lastname@example.org.
