The boards seem to have been sold now.

Looks like the only thing that can generate a amplifier fault

Why would you connect the torch breakaway switch to an amplifier fault? That is wrong

Looks like the path in your ini file  to your Ethercat xml file is wrong

Personally, I think compiling through source code will have a much better effect. Usually, different environments lead to very poor compilation results...

Thank you very much for your answer. After repeated tests, I found that this BUG occurs on a specific machine. I have two identical machines at hand. One machine will never have this problem no matter what, while the other machine always has it. After this, I updated to 1.25.1 and this problem was solved!

Cheers! scottlaird!!!

yes, I include rtapi.h file.

The 7I97T is likely repairable if only the encoder interface chip(s) are damaged.

You might check if any encoder inputs work.

Ah, thanks for setting me straight.
Since I'm getting encoder signals to the 7i97t, but it's not getting that signal to linuxcnc, than I assume that the high frequency start somehow damaged it.

if you measure across A+ , A- you should get alternating polarities like your +3.5V, -3.5V

If you measure A+, A- relative to ground they should be close to ground in one state
and > 2.4V in the other.

I set the encoder jumpers on the 7i97t to ttl and tried grounding a+, b+ and i+ while watching the corresponding hal show pins and they didn't light up.
So it looks like the encoder signals aren't getting through.

I then put my multimeter on a+ a-, b+b-, i+ i- and got 3.5ish v, but on both a and b at the same time. Shouldn't one phase be high like 3.5v while the other phase is low, like .5v? It seemed like they were jumping between -3.5 and 3.5 when i moved the motors instead of jumping between .5 to 3.5. Is this wrong or am I mixed up?
Except for the z axis which was reading more like 5.22v.
