CAM Assist writes log files on your computer. CloudNC support uses them to see what went wrong. Where they are depends on your CAM package.
Where are the log files?
| CAM package | Log folder | What's in it |
|---|---|---|
| Autodesk Fusion (Windows) | %APPDATA%\Autodesk\Autodesk Fusion 360\API\AddIns\CAMAssist\logs |
cam_assist.log (one file per day, last 14 days kept) and cloudnc-sdk.log |
| Autodesk Fusion (Mac) | ~/Library/Application Support/Autodesk/Autodesk Fusion 360/API/AddIns/CAMAssist/logs |
Same as Windows |
| Mastercam | %ProgramData%\CloudNC Ltd\CAM Assist\logs |
One subfolder per session, named with the date and time it started |
| Siemens NX | %ProgramData%\CloudNC Ltd\CAM Assist\logs |
One subfolder per session, named with the date and time it started |
| GibbsCAM | %ProgramData%\CloudNC Ltd\CAM Assist\GibbsCAM\log |
One log-<date and time>.txt file each time you click CAM Assist |
| SolidCAM | C:\Users\Public\Documents\SolidCAM |
CamAssist_log.txt. In SolidCAM 2026 each session is added to the end of the file. In SolidCAM 2025 the file holds only the last session. |
Mastercam and Siemens NX share the same folder. If you have both, the subfolder names tell you when each session started.
In SolidCAM, logging is off by default. CloudNC or SolidCAM support will tell you how to turn it on. The log is written to C:\Users\Public\Documents\SolidCAM\CamAssist_log.txt, or to %TEMP%\CamAssist_log.txt if that file can't be written.
Open the log folder
On Windows:
- Copy the path for your CAM package from the table.
- Open File Explorer, click the address bar, paste the path and press Enter.
The ProgramData folder is hidden, so you won't see it by browsing. Pasting the path still works.
On a Mac:
- In Finder, click Go > Go to Folder.
- Paste the path and press Return.
What to send CloudNC support
- Zip the log folder. For Mastercam and Siemens NX you can zip just the subfolders from the time of the problem.
- Send the zip file and the part file to CloudNC support, with the date and time the problem happened.
