Need help setting up XYYZA for stepper motors

My Dual Y 3 axis works fine.  I am trying to setup a 4th rotary axis.  I used the setup wizard for steppers.  I doesn't have a XYYZA  option, only XYZA.
i attached the Y step and direction output to two outputs that appear to drive both Y motors on the Halscope. However without having a Y0 and Y1 as in the 3 axis setup I am hesitant to try driving the steppers as I am not sure they will both act in the same direction.  Looking at the 3 axis setup I would need 5 joints (0.0.0.0.0) to do this.  

Would greatly appreciate some insight.

Thanks in advance

Just take you XYYZ config and modify it by adding an extra joint and XYYZA
At this stage, you need to leave pncconfig or stepconf behind and work directly with your hal and ini

I rather suspected that was the correct way to do it. I'll work on it.

thanks for you help.

Thanks again for your help.  Almost there but a few glitches. The 4th Axis program opens; X,Y and Z axis move however Y will not home. A axis homes but shuts the program down when attempting to move it.  Some type of (following error)..
I added a hash tag to the 3 axis enable line as I was getting an error saying the pin was already attached to another signal. When I applied the hash tag the program opened up.

Would greatly appreciate your comments.  I'm sure you would see the errors much sooner than I would.  It's been quite a learning curve, something I knew I would have to do sooner or later.

thanks in advance
