7I76EU pin names are identical to 7I76E names

Can you post your current hal/ini files?

it's possible...i measured 24V on the output pins.....these lines look different then when the machine was last operational but i had ChatGPT produce these...they don't seem right to me but i don't know enough...my board is a 7i76EU so i was thinking of replacing 7i76 with 7i76EU......if i comment these lines out the z axis brake doesn't release...

TRUE

TRUE

TRUE

You would not normally see much of a change in STEP
pin outputs as the STEP pulses are short and do not change
the average voltage ( what a voltmeter reads ) very much.

You should see a change in the voltage on the DIR
pins when jogging in different directions.
 
It this possibly an issue with the motor drive enables?
