7i96S card arrived what setup is recomended

Yes, just use whatever powers the 7I96S +5V

I got the ENA setup and working properly. Enabling the machine turns on the drives as expected. Now I just have to work on handling the ALM signal when there is a problem reported. What is the current way of handling this? I think I need to tie in fault-in from the motion module.

Typically you would wire it (in hal) to joint.0.amp-fault-in
(a true on any joint.x.amp-fault-in  will cause LinuxCNC to halt motion)

I did this but now run into a different issue. The driver alarm is setup to signal high for ALM. When I have put the following in my custom.hal to use the alarm signal to disable the drives. This works fine for disabling but I can seem to reset.

To clear the alarm, I have two options:

1. Power off the drives
2. Set the drives to disable and then back to enable. This is a "soft" reset and works when I comment out the line above.

I'd prefer option 2. The first part of the reset is actually completed by the ALM signal in (disabling the drives). However, when I try to turn the machine back on via the axis gui, it won't let me since the amp-fault-in pin is set high.

So the fault pin is only cleared when the drive is re-enabled?

If so, you might need some hal logic (and + ones-shot perhaps) to mask the error until a bit after
the change to machine-on state

So the fault pin is only cleared when the drive is re-enabled?

That sounds about right and the fault is preventing me from clicking the machine on in the ui.
