Hello, 

the normal CAM Operations are no problem and now I understand so setup them but when I try 'Multi Axis Milling' in a Flow Operation I am not able to generate the g-code for it with the given Pocket NC post processor. 

Here is the log from the Fusion trying to generate the tool path with the PocketNC Post

My Setup works fine with the other CAM operations.

But when I try to use the Flow operation with Multi Axis than it don't work.

Any ideas?

The x and y axis of the WCS are the wrong way around. When I fixed this it was fine, for operations from the top it would not matter. With the table flat z points at the spindle and x should point to the right as seen by the spindle.

Also the origin of the WCS should be at the end of the sketch line (~21.3mm long) coming from the table. 

The error was actually related to the A axis trying to point too far downwards I think because of the coordinate system. The error I saw was:

Error: Tool orientation is not supported for available machine axes.
Error at line: 1

Cheers,

Graham

Thank you it worked. After I tried several setup variants yesterday with you hint it fixed it. 
Also I recognized that the cam failed, when I increase the 'Maximum tilt angle' over 115°. When I do that the simulation seems fine but it won't generate the post. But 115° works fine for that job. 
Thanks again for the help.

No problem and it was handy because I forgot you could do 5-axis flow, it used to be in the multi-axis section I think and they moved it because a lot of people didn't realize it could be used for 3-axis.

Cheers,

Graham
