Is there a way inside or outside of emc to “manually” apply 10V out of the 7i48?

Look in Machine->Show Hal Config.

You probably see something like pid.0.out => hm2_5i23.0.pwmgen.0.value if you look around the pins.

So, you need to type setp hm2_5i23.0.pwmgen.0.value 1 in the box at the bottom (which you might have to expand the window to see)

However, you can't set the value while it is linked to the PID output, so you first need unlinkp hm2_5i23.0.pwmgen.0.value.

Note that all these names are off the top of my head, and might be only partly correct.

You would have to link them up with a net command in a .hal file. Once classicladder is up and running open up Show Hal config and see the classicladder pin names and the gpio pin names.

I made some significant changes to the 7i64 driver last night.
This is good news and bad news for you.

The good news is that card start-up should be a _lot_ more stable now.
The bad news is all the pin names changed. (to match the EMC2 canonical spec, which I hadn't seen before).

I suggest getting a fresh build of 2.5 and changing the pin names before you get too much further.

Can a spare encoder location on the 7i48 be used for the mpg?

Yes, and it seems like a good idea to do so.

I rechecked my wiring last night and it all looks good. Is there a way to watch for the the index input in hal Scope?

Not really, with Mesa encoder counters. You should be able to see if index-enable is changing state on Halscope though.
It should go high at some point in the homing cycle, and then low. It is actually that transition and the value read back that EMC2 uses for the homing index.

Perhaps the index polarity is wrong?
