Mastercam shows this when you start CAM Assist or Cutting Parameters Explorer and the part has unsaved changes. CAM Assist works from the saved file, so it has to save first. It's safe to continue.
File will be saved, do you want to continue?
What happens when you click Yes or No?
- Yes: CAM Assist saves the part, closes it and opens it again, then starts.- No: nothing is saved and CAM Assist doesn't start.
If you can't write to the part file (it's read-only or locked), CAM Assist saves a copy in your Windows temporary folder and opens that copy instead, without telling you. Any work you then do is in the copy. Use Save As to save it back to your own folder.
"Something went wrong with saving the file"
Something went wrong with saving the file. Please check logs for more details.
It follows a message that names the file: "Failed to save changes to file …" or "Failed to save temporary file …".
- Check the folder in the message exists and you can write to it.
- Close any other program that has the part open.
- Use Save As to save the part to a folder you can write to, then start CAM Assist again.
"Save the part before starting background CAM Assist."
The part has never been saved, so it has no file. Save it as an .mcam file, then click CloudNC CAM Assist again. Cutting Parameters Explorer doesn't need this.
Still seeing it?
If you've done all of the above and still can't start CAM Assist, contact CloudNC support. Include the part file and the log files from %ProgramData%\CloudNC Ltd\CAM Assist\logs.
