Okay, it looks like 1.17.1 has been built and should be available. If you're using a semi-standard setup, then `sudo apt update; sudo apt upgrade` should grab it.
I also filed github.com/linuxcnc-ethercat/linuxcnc-ethercat/issues/318 about fixing the period and frequency stats.

thank you again.
Starting linuxcnc gives the same error. In dmesg I get:

Okay, let's try 1.17.2 then . At least it's a new object this time -- one of the status pins that we weren't even reading yet.
If this fails with a similar error, can you include 'ethercat pdos -p 8'?

This plus all of the weird little issues I've have with CiA 402 make me wonder if we want to have a trivial way to specify sync + lcec_pdo_init() settings together. I'd love to be able to say "please map this object, of size X, for input, and record info about it here -->"
Maybe bonus points for "...and expose it as a pin named A, possibly with mapping function B"
For CiA 402, I currently have 42 optional pins *per axis*, each of which takes 17 lines of code to handle. It's totally boilerplate at this point, mostly handled through C preprocessor abuse, but it's still annoying. The common case of "just map these objects to these pins" takes too much code and it's too hard to read.
Unfortunately, this is starting to look more like C++ than C. So it goes on the "gee, it'd be nice" list, not the "go out and write it" list.

OP! I have OP! WOOHOO!
Thank you Thank you Thank you so much!
Still have to attach my encoders and try it out and I will let you know how it goes. I didn't attach them before because the documentation said something about 5, 12, or 24 supply for the encoders and didn't want to risk it.

I've hooked up the encoders and the counts are working on both channels.
I'm not really sure the change from last night. I added back in my servo drives in ethercat-conf.xml so I could move the XY stage around to test some home switches and it was working.
I was working on in the morning trying to get tigervncserver running and did some apt-get update & upgrade. I was doing that last night too when trying to get the updates you were posting. Perhaps I only got the latest update when I did it again this morning.
In anycase, thank you again.
