Red Init & Done Lights on 7i92M

If you have field power and neither CR15 nor CR16 light, its possible the 7I77D was damaged as well.
 

Ahh, well, so it goes. I've ordered a 7I76U because I think that the D models were actually going to be more difficult to wire anyways, as I'd like some sourcing outputs.  I'll see about getting an RMA for the 7I77D I have, and can function test the existing 7I76D when I get the new 7I92TM.  5 axis + spindle and 48 I/O pins should be plenty to get this mill up and running, and that leaves me some boards to experiment with in the future

Thanks for the quick replies, nice to keep momentum up on the project!

I wouldn't call my solution a preferred one, it's just the implementation I chose.
Please ask questions and do some research, I'd hate for my way to be sub par and lead another member the wrong way. So far nothing has gone wrong.
If you do find any info to the contrary I would be most appreciative if any failings in my advice were pointed out.

From the manual, it says that it handles the passthrough power via otherwise unused pins on the cable, so that seems like a fine solution to me. As they control both sides of the board, it's not like you need to worry about things going wrong in that sense (as long as you use the appropriate cable).  It's also nice to simplify the power wiring a little bit.  

I will definitely let you know if I find some other solution that seems more appropriate for whatever reason, but I figure designed and documented in the manual is probably good to go

Why would you be attempting to offer a LPT card in this instance ?

Honestly I work in technical spaces and I’m lucky to have the means to support companies that do this kind of work, and I’m happy to pay Mesa for their cards, given how much support they offer. I will return cards for RMA, and I don’t mind having spares.

Doing this build has been much more enjoyable than I expected so I figure I’ll probably also build an CNC lathe or convert my plasmacutter to Mesa control at some point. 

I appreciate the offer of a parallel card so I could boot my existing board but I’ll be able to check with the new control board that is coming and work is gonna consume me until those cards show up anyways
