Cutting Parameters Explorer lets you refine the feeds and speeds of an operation CAM Assist created in Mastercam. This article covers the messages you may see when you open it or save from it. For how to use the explorer itself, see The Cutting Parameters Explorer.
Did you open it from a CAM Assist operation?
Cutting Parameters Explorer works on one operation at a time, and only on operations CAM Assist created.
- In the Toolpaths Manager, select an operation CAM Assist created.
- Right-click it and choose Open CloudNC Cutting Parameters Explorer.
If no operation is selected, you see:
Error loading add-in. Error code: 900. Message: Open Cutting Parameters Explorer from an operation in the toolpath manager..
Nothing is wrong with the installation. Select an operation and try again.
Opening the explorer runs the same part checks as CAM Assist. If you see "File will be saved, do you want to continue?", see Save the part when starting CAM Assist in Mastercam. For machine group, stock or Master Model messages, see CAM Assist won't start in Mastercam.
Does it say the stock material isn't supported?
The selected stock material is not supported by cutting parameter generation
CAM Assist ran with a material it can't calculate cutting parameters for, such as a custom material. The explorer offers only Close. Run CAM Assist with a material from the CloudNC material list to use the explorer. See Cutting Parameters Explorer unavailable.
Is Save cutting parameters grayed out?
Save cutting parameters is available once every tool usage tab has cutting parameters. Open each tab and wait for its values to load.
Did the save fail?
After you save, a short message says "Operation saved successfully." or "Operation save failed."
If Mastercam also shows this warning, part of the save may have been written:
The save may have partially completed. Further saves are blocked. Check the cutting parameter values in Mastercam, then close and reopen Cutting Parameters Explorer before trying again.
- Check the operation's feeds and speeds in Mastercam and correct them if needed.
- Close Cutting Parameters Explorer.
- Open it again from the operation and save.
Other messages
Some versions show these instead:
| Message | What to do |
|---|---|
| "CloudNC Cutting Parameters requires CAM Assist to be run" | Run CAM Assist on this part, then open the explorer from one of its operations. |
dialog.popup.cpe_not_available |
The last CAM Assist run used a custom material. The explorer can't refine feeds and speeds for it. |
| "This is a demo version of Cutting Parameters Explorer and therefore can only be used with the CloudNC demo parts and tool library." | Use a demo part from Open a Demo Part with the sample tool library. |
| "License error: Unable to log into CAM Assist. …" | Check your subscription. See Check your CAM Assist subscription. |
Still not working?
If you've checked all of the above, contact CloudNC support. Include the part file, the name of the operation, and the log files from %ProgramData%\CloudNC Ltd\CAM Assist\logs.
