I was hoping @tar_san could post his files, as he indicates he got homing with external limit and origin switches working. I had thought I had homing figured out back in January, but discovered it was only working for Z index pulse homing, not external switch homing. I then had to set the project aside for six months due to a high priority consulting project, and am back on my LCNC ethercat quest again.

Yes, that should work.

You can use pncconf or MesaCT to created a configuration for the 7I92.

You can use a similar daugtercard if the Benezan card is not supported. 
 

Hello,

After some research, I came to the conclusion that a 7i92t could replace a parallel port. My old computer died and I purchased a mesa card and attached it to a computer running LinuxCNC 2.9.4. I flashed the 7i92t_benezanx2d firmware following suggestions in another thread. 

I'm trying to control a very simple CNC Lathe by Taig. The signals that it requires on a parallel port are:

ESTOP - Pin 1
XDIR - Pin 2
XSTEP - Pin 3, Inverted
ZDIR - Pin 4
ZSTEP - Pin 5, Inverted
SPINDLE - Pin 16. Just ON-OFF, no speed control.

Is it possible to make this work with a 7i92t? 

I'm attaching the parport .ini and .hal that I was using.

Thank you in advance.
 

just to be clear, the stepper motors do run when using the stepconfig wizard, the question I would ask is, will the joints Y, A run in tandem from the LinuxCNC job interface? Does the application recognize the two as one joint and move them accordingly.

Yes, if  they were selected as tandem axis during configuration.

They have single turn absolute encoder.
I don't think its a motor issue because all of them do it exactly the same, or they are all fine someimes. I put together a better b450 motherboard with a ryzen 3200g. Seems better than the $0.50 HP motherboard already. I think it does have realtek chip so I have an Intel card to stick in it too.

jimmyrig, I am very new to this and do not know much about altering the g-code, sorry not sure what to do there.

The Premier Plasma table table and computer setup all worked great when it was windows. The computer died and I chose to go the linuxcnc rout with CNC wood router. I did not know this was going to be a 2+ year setup. I would have sold this thing and bought a small wood router setup with everything pre-installed ready to go.
