When you click CloudNC CAM Assist in Mastercam, CAM Assist checks your machine groups before its window opens. If a check fails, you see one of the messages below and CAM Assist stops. The same checks run when you open Cutting Parameters Explorer.
"No machine groups available."
The part has no machine group.
- On the Machine tab, click Mill and choose Default (or your machine) to add a mill machine group.
- In the Toolpaths Manager, expand the machine group's Properties, then set Stock setup and Master model (the part body).
- Click CloudNC CAM Assist again.
"No stock specified in machine group: …"
The first machine group has no stock. CAM Assist accepts box, cylinder, solid, mesh and STL-file stock.
- In the Toolpaths Manager, expand the Properties of the machine group named in the message and click Stock setup.
- Define the stock.
- Click CloudNC CAM Assist again.
Later machine groups don't need their own stock. A group without stock starts from the previous group's stock.
"No Master Model specified in machine group: …"
None of the machine groups has a Master Model. The message lists every group.
- In the Toolpaths Manager, expand the Properties of each machine group you want CAM Assist to program, click Master model and select the part body.
- Click CloudNC CAM Assist again.
If at least one group has a Master Model, CAM Assist starts without a message and ignores the groups that don't. If a setup is missing in CAM Assist, check its machine group has a Master Model.
"Mesh bodies are not supported, but are being used as …"
CAM Assist can't use a mesh body as a part, fixture or avoidance body. The message says how the mesh is used and, where it applies, in which machine group:
| Message ends with | Where the mesh is |
|---|---|
| "…as master models in the "<group>" machine group" | Master Model in Job Setup |
| "…as fixtures in the "<group>" machine group" | Fixture in Job Setup |
| "…as avoidance geometries in the "<group>" machine group" | Avoidance body chosen in CAM Assist |
Replace the mesh with a solid body, or remove it from Job Setup. Mesh stock is fine.
"Unsupported stock type used in machine group"
The stock in one of the selected machine groups is an entity that isn't a solid or a mesh. Change the stock to a box, cylinder, solid, mesh or STL file.
Still not working?
If you've checked all of the above, contact CloudNC support. Include the part file and the log files from %ProgramData%\CloudNC Ltd\CAM Assist\logs.
