ClassicLadder TUrret using mesa 5i25 w 7i76

Hello everybody,
I am trying to get my home built turret to work with linuxcnc via classic ladder. I'm a bit unsure how to even start honestly. I've checked out the example turret tutorial but I'm pretty confused about how to get this to work with the mesa 5i25/7i76 and its stepgenerator.

Here's a photo of the setup.

I've got an air cylinder that actuates the turret connected to output-03. A PNP proximity sensor on the main pulley as index connected to input-07. There's another PNP prox sensor to sense the turret closed as well. And lastly a little step/dir closed loop stepper hooked up to stepper2. It's a little mechaduino connected as a step/dir stepper. Do I need to define another stepper, say Y or A in my ini and hal files? Then what do I do about the classicladder step and dir outputs?:
net tstep <= stepgen.2.step => parport.1.pin-17-out
net tdir <= stepgen.2.dir => parport.1.pin-16-out

Any help on this would be super appreciated. I'm a complete newb when it comes to linuxcnc.
Thanks in advance.

Ok first what sequence of events need to be done for this to work.

Does one turn the turret open loop till a sensor fires or does it move to a position?
Does it need to be homed or do the sensors detect the absolute turret position?
Are you using a parallel port or a MESA card (I saw your other post - so probably MESA)
have you had this running with something else, if so what was the sequence used?

I like to make a list of inputs and outputs etc and what they mean.
input 1 bit index of position 1
input 2 bit turret closed
output 1bit air cylinder closed

output 2 bit step
output 3 bit direction

or
output 2 s32 position

then write a sequence of events.
Then try to duplicate in ladder programming.
Then add fault code.

Something like that anyways.

Thanks guys, I really appreciate your help. I've got it running with a remapped M6 and some sweet code from Andy. I couldn't figure out how to control the position of the turret in classic ladder. I don't know if it's possible. But with some remapping and a little simple gcode with o word logic I've got it running the way I want. Thanks again for all the support.

any chance you could post what you did for future reference?
