Machining Extension - Rotary and Rotary Pocket
Hello @marksp20hdWELNX
which post processor are you using, do you use a machine configuration in the setup?
The error is basically, given the machine kinematic, i.e., axis direction and range, the position requested cannot be achieved.
Apparently, the tool needs to reach A101, and C450, and it is not possible.
As we have not idea about the machine, and the kinematic defined in the post, or in the machine configuration file, further analysis is difficult.
Regards.

Yes you can share the elements, so we have a clear understanding of what is defined in Fusion, what the post is capable of.
For sharing the Fusion file :
You can either share a link to your Fusion file. See:
https://knowledge.autodesk.com/support/fusion-360/learn-explore/caas/sfdcarticles/sfdcarticles/How-t...
or you can save an archive (f3d, or f3z) and share it on the forum
https://knowledge.autodesk.com/support/fusion-360/troubleshooting/caas/sfdcarticles/sfdcarticles/How...
And you can attach the post to the thread.
Regards.
Unfortunately the kinematic picture is not showing the A axis limits.
when the rotary axis of the machine are all at zero, what is the machine posture.
Do you have the tool "normal" to the table surface as in this picture
Or the tool direction and the table centerline are orthogonal, as in this picture ?
Regards.

Hello @marksp20hdWELNX
Let's start with the post tuning.
Inside the post, after editing it with a pure text editor, search for the onOpen function.
At the start of that function, you will find :
This must be changed to the correct limits:
gRotationModal.format(69); // Default to G69 Rotation Off
if (true) { // note: setup your machine here
var aAxis = createAxis({coordinate:0, table:true, axis:[1, 0, 0], range:[-20, 110], preference:0});
var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, 1], range:[-360, 360], preference:0, cyclic:true});
machineConfiguration = new MachineConfiguration(aAxis, cAxis);
setMachineConfiguration(machineConfiguration);
optimizeMachineAngles2(0); // TCP mode
}
Notice the changes for the range definition on the aAxis definition.
After that the issue is in your defintion for the setup.
The Z axis is not oriented correctly.
When you machine is at zero on all rotary axis, the Z axis is perpendicular to the table.
It's not your current defintion.
The actual setup if i import a ac table table machine and put the part on the table:
or
In fact, your Z axis must be oriented as the Y (green) axis.
This way, the part is located correctly on the machine, and the g-code is posting.
As the machine does not support TCP, I am not sure the result will be 100% correct.
We may have to handle the pivot distance between the centerlines of the rotary axis.
Maybe that why your setup is not at the end of the part?
Regards.
