Run CAM Assist sits at the bottom of every stage. It stays disabled until every input it needs is valid. Hover over the button to see why. If there are several reasons, they're listed together, separated by •.
The Overview stage also shows which stages are blocked. A stage with a problem has a colored badge in the top bar; its status banner lists what to fix. See The guided workflow stages.

Does the button say "Run with warnings"?
You can still run. Some stages have warnings, such as machinability issues or tools to check. Click it to run anyway, or fix the warnings first.
Did a "Please select at least one valid setup" message appear?
Please select at least one valid setup to run CAM Assist!
This brief message appears when no setup is turned on, including when a part opens with no usable setups. Turn on a setup in the Setups stage. If there are none to turn on, check the part's setups in your CAM package, then restart CAM Assist. See Set up your setups.
Still not working?
If you've fixed every reason in the tooltip and still can't run CAM Assist, contact CloudNC support. Include the part file and your CAM Assist log files: see Find your CAM Assist log files.
