Hi Guys, I am having trouble getting my lathe to work.
It is an Old Superslant Hardinge.  It has 4 axis, 2 turrets each with an x and z and each with 8 tool changer.
The problem I have is that I have a working hal that connects to the boards, and all the io's are working.  But the drives both axis and spindle don't do anything.  The axis I know the problem is that im wired for step and direction and the configurator doesn't give a setup for that, and using the step configurator and blending the file is giving me a major headache.as its difficult to see what parts of one I need and what parts I can't have.
I am running 7i76-7i77 and 7i64.
Any suggestions as to how I can make or blend a hal file that will do what I want would be appreciated.

It would be much better to give us correct info about your setup, like what is attached to 7i76 and 7i77?
Or is it a 7i76E with 7i77?
Did you flash the correct firmware for whatever is in use?
What does readhmid return?
Do the boards have 5V and Field (12-24V) power?

7i76E is connected to the computer through ethernet, the 7i77 connects to the 7i76e with a ribbon cable and the 7i64 connects to the 7i77 with a modified ethernet cable.
The boards have 5v and 24v field power.
It has been a while since I wired and had time to do the cards but I remember that I did flash one for some reason or another. Does it need different flashing for step direction than for analog?
And sorry again, as I said it has been a while since I had time to get into this again and don't remember where to type readhmid

No worries, we do need correct info to be able to give any help, 7i76 and 7i76E are the same thing but NOT the exact same thing.
Mesa can do step/dir and analog at the same time and so can LinuxCNC, so that is easy, just use mesaflash to check what firmware is already in the 7i76E, then we can decide if a flash is needed.
see in a terminal
man mesaflash
for how to use it.

Thanks for the quick response, I am always surprised at how quick you are.
Unfourtunatly I had to leave the shop and go home. In the morning I will see how well I can figure out how to get a man mesaflash to see what I have.

Ok. I put man mesaflash in terminal and it came back with 'no manual entry for mesaflash.
I believe there is a sudo command to ask what the board information is, but I can't remember what it is.

I put in
mesaflash --device 7i76e --readhmid

it said 'no 7i76e board found
I just got called out on a service call, so have to go, unfortunately.

You need to provide the cards IP address:

mesaflash --device 7i76e --addr 10.10.10.10 --readhmid
or
mesaflash --device 7i76e --addr 192.168.1.121 --readhmid
