If you connected say 24V to the step/dir pins, you may have
blown up the 27 ohm resistor networks between U19 and the
terminal blocks.

Thanks. Those resistor networks are RN3, 7, 24 and 32? What packages are those? I will try to measure the voltages from the U19 directly and if it's ok then I will change those resistors.
