Added A axis to XYZ mill, what can be done in AXIS? was created by Wirewrap
I recently added a rotary workpiece holder to my working XYZ mill. It rotates around X, center of rotation is at Y = 70mm and Z is not known until after touchoff. Using AXIS 2.7.12
The actual physical motion works as expected, but the AXIS display is confusing, I have tried both axyz and xyza.
How can I tell AXIS where the rotational axis is centered?
Is there a (simulated or real) machine setup to look at? I have found 3-axis and 9-axis sim examples.

That should be fine.
buildbot.linuxcnc.org
Your kernel seems to indicate Wheezy and RTAI, so you would use:
deb buildbot.linuxcnc.org/ wheezy master-rt
deb-src buildbot.linuxcnc.org/ wheezy master-rt
You can do this in the GUI if you want.
System->Synaptic Package Manager
Settings->Repositories
Then click the "Add" button.
This is what mine looks like (as you can see I have set it to an old 2.6 version for testing, but Master is there as an option)

OK,
I will try to setup a Master environment and see what happens.
Maybe I am currently running a too old release?
Linux debianRT 3.4-9-rtai-686-pae #1 SMP PREEMPT Debian 3.4.55-4linuxcnc i686 GNU/Linux
AXIS 2.7.12
That should be fine.

Installed master branch on a test machine that is identical to my shop machine but missing stepper motors and the cast irom of the actual mill.
At first Axis start I got an offer to convert my old setup to this new version. I accepted the offer.
This is the screen after start and load of the test program "ring"
Screen after "home all", This is different from 2.7.12 in that axises are shown in manual mode
Here I tried to move the tool tip to the perimeter of the workpiece and touch off Z to 0. Seems to be a bad idea.
Funny that the diameter of the work piece changes.
Then I tried to move the tool to the perimeter and touch off W. Now this seems promising. I will try it on the real machine and see how it works. Trying to test touch off without a real machine is very confusing to me.
