Yes, I'm using the common 5-axis BOBs from china, one on each port (P1 and P2).
That said, I don’t actually need all 10 StepGen channels. My machine only uses 4 axes, so I’m hoping to free up many of the StepGen-related I/O pins and use them as general-purpose I/Os instead.

Also, since the 7i92 headers are mirrored (P1 and P2), both BOBs give access to the same type of GPIO pins. I’m hoping to take advantage of that symmetry and assign more pins for inputs (e.g., limit switches, ArcOK, ohmic probe, thc UP /down etc.), and just a few for outputs (torch on/off, float switch reset, laser etc.).

Ideally, I'd like a bitfile that allows:

At least 10 inputs and 5 outputs for general machine control

Fewer StepGen channels (maybe 4 or 5 max)

If a bitfile like that exists — or if modifying an existing one is straightforward — I’d really appreciate the guidance.

Thanks again for your help!

Best regards,

PncConf works in Live!!!!! it was the language !!!!!!!!!! I am very happy!!!! thank you!!!!!!!!

I continue now with the VFD!!!

Thank you!!!!!!!!!!

Thank you all for the responses. The VFD GA500 is already installed in the machine and I don’t have it here. I have an LS600 on my work desk which I am using for the tests. I will try to send you the information you are requesting as soon as possible.

PCW !. Thank you for coming back! From the heart!

I advance the board that I am using in the TB4 connector, I believe, as PCW explains, that I am not supplying the 10vcc. I am going to check the LS600.

 

There is no tension on pins (1-2) (1-3) of the TB4

That means no Spindle output is possible.

The 7I76/7I76E/7I76EU do not supply the 10V.
The spindle output on these cards works as a
potentiometer. Typically the 10V is supplied by
the VFD.
 

The OP was supplied with a config as requested for 4axis and a spindle, to 24k I think, by PCW. Even with is he could not get an output, taking this into account PncCONF is not the issue.
If the OP could be so kind as to supply a picture of the wiring of the actual spindle connector and a diagram as well of how he wired it I think that would be quite helpful. This is the second time I have made this request.
To OP seems to have missed or ignored the bit about PWM not being involved in configuring the spindle.
Just making a guess I suspect that spindle + and spindle - are not being supplied with an isolated voltage. If this is the case spindle out with not have a voltage that is in line with the selected spindle speed.
Wiring of the opto isolated outputs can be tackled later.
To reiterate the OP has a config supplied by PCW, which we can take as being gospel and if the board is wired correctly will work.
For testing I would not have the spindle connected, I would just be monitoring the spindle output with a multimeter referenced to spindle - .

This is actually how I went setting up my spindle, but using a smart serial board as I required the servo driver to be some distance from my 7i76 and did not want a small analogue voltage being transmitted over a long cable. Paranoia may have had been high that day.
