I have been running a modified LinuxCNC PP for a while, with the A-axis enabled.
I can't recall if I have ever used it, though.
I am trying to machine a hex on the end of a part using A-axis rotations. I have defined a tool orientation for each operation, and it all works fine in the simulation.
When I try to Post, however, I get no G-code, and the log is not helpful:

I think that I have tracked the problem down to this line in the post, by adding some "warning" commands before and after.
function getWorkPlaneMachineABC(workPlane) {
var W = workPlane; // map to global frame
warning("Before");
var abc = machineConfiguration.getABC(W);
warning("After");
if (closestABC) {
Gives this output:

So it seems that the PP is giving up during the "machineConfiguration.GetABC(W)". But that does not appear to be code in the .cps file.
I have tried starting from scratch with the latest LinuxCNC generic post, and the EMC2 one too (after following the general instructions to add an A-axis)
It looks like the issue might be with my machine configuration. But I am not clear if that means the config in the post or the kinematics tree in the GUI.
I am working on a Mac, so most of the PP screenshots that I have found are no help, my PP dialog box looks utterly different, and I see no option to define the A-axis axis there.
Solved! Go to Solution.
