Use this when CAM Assist sends a program back to Siemens NX and some operations are missing, have no toolpath, or NX shows error messages while creating them. Each message below names the operation it's about.
Did NX say an operation "will be skipped"?
NX shows one message per operation it couldn't create, for example:
Failed to instance operation template for the <operation> operation. Operation will be skipped.
Other messages end the same way ("Missing target faces…", "Unsupported tool type…", "Failed to build stepovers…"). The rest of the program is still created.
- Note which operations were skipped.
- Click CAM Assist and send the program again.
- If the same operations are skipped, create them yourself in NX.
"Failed to instance operation template" can also follow this message:
Error loading Siemens NX operation templates.
Reopen the part in Manufacturing and run CAM Assist again. If it repeats, reinstall CAM Assist. See Install CAM Assist for Siemens NX.
"Failed to retrieve tool UUID referenced in toolpath <operation>." means NX couldn't create the tool for that operation, so the operation is skipped too.
Did NX say "Failed to generate toolpath due to error"?
Failed to generate toolpath due to error: <NX error text>
NX created the operation but couldn't calculate its toolpath. Generate the toolpath for that operation in NX and check the NX error. If it's about a license, see Which Siemens NX licenses does CAM Assist need?.
Did NX say "Failed to use tool in file"?
Failed to use tool in file. Creating copy to refer in <operation> toolpath.
CAM Assist couldn't find the tool from your part by name, so it created a copy of it for that operation. The operation is created. Check for tools with duplicate names in your part.
Did NX say "Unexpected error while creating operations"?
Unexpected error while creating operations.
Please ensure you are running the latest version of the CloudNC CAM Assist add-in and restart the application.
CAM Assist stopped creating operations. Any messages shown just before it, such as Workpiece errors, say why. See CAM Assist doesn't find my setups or stock in Siemens NX.
- Undo the partial program in NX.
- Install the latest CAM Assist for your NX version and restart NX.
- Run CAM Assist again.
Are operations there but without toolpaths?
That's the Toolpath Generation setting, or you answered No to Program Generation. Generate the toolpaths in NX. See What does CAM Assist add to my Siemens NX part?.
Is the count in the final message more than you see?
When finishing is on, CAM Assist ends with:
CloudNC CAM Assist generated <n> operations, machining <x> of <y> surface(s).
The operation count includes skipped operations. If it asks you to "create strategies for the remainder of the part", program the remaining surfaces yourself.
Did you stop CAM Assist while it was creating operations?
If you abort in NX while operations are being created, CAM Assist undoes everything from that run. If NX then shows "Unable to undo operation. The current session may be in an unstable state.", save the part under a new name and restart NX.
Still not working?
If you've checked all of the above, contact CloudNC support. Include the part file, the names of the skipped operations, and the log files from %ProgramData%\CloudNC Ltd\CAM Assist\logs.
