Configuring a rotary axis on a router

Hi
Apologies for posting this again but I would like/really need, to get this going
I am struggling to configure a rotary axis on a xyza gantry router with two steppers on the x axis. I have got x y and z to to move and home okay and there is power to the stepper on the a axis, but it will not jog. I have attached hal and ini files as will as the pin assignments for the breakout board. I would appreciate some simple instructions/directions because I just can't get my head around how these files work. Any help on this issue would be very gratefully received.
Thanks
Aaron

Any error messages?

Hi tecno
There don't seem to be any error messages, However when I open lcnc from the command line I get some strange text:

Does this have any bearing on the issue?

Cheers and thank you

You have the same question in this thread
forum.linuxcnc.org/49-basic-configuratio...xis-on-a-cnc-rrouter

Answers given there.

Several days back, i've spent about 20 minutes trying to find this as i was sure it was a double post, could not find it !
No wonder, it has the same exact title !
@aaron
No double posting, i am sure you posted this after i answered the other thread and you just ignored it.

@Tecno
Thank you.

Very sorry for double posting. I was getting a bit desperate and didn't see your post
Once again very sorry
Aaron
