BOB does not generete step

good evening, i am new to linuxcnc and i wanted to ask you for a hand

I tried to control the Nema 23 motor and the driver (online stepper dm542t) through the BOB bought here

www.amazon.it/Macchina-Incisione-Interfa...+%2Caps%2C188&sr=8-5

to create my .hal and .ini file I used the stepconf tool but when I have to test the engine, it doesn't run. so I performed these operations to resolve various doubts:

- I tried to control the driver with arduino by creating a pwm generator, and everything works
- i tried to check the output voltage at pin step and pin dir, on step pin there is not voltage and on pin pin there is.
- I tried to change parallel port to verify that the problem was not upstream

can you give me a hand to solve the problem? I don't know how to proceed anymore. thanks

Could you please attach your hal & ini files please.

Could you also give the output ofjust the info about the parallel port will be fine
&
Also could provide some information about your computer, whether the Parallel Port is built on to the motherbord or a PCI - PCIe card and the version of Linuxcnc ?

the computer is hp compaq 6000
linuxcnc version is 2.9 pre
the parallel port is on pci

linuxcnc read my parallel port bcause when i run ptest.hal it does not give me anyone errors

i think that resolve this. i confirm that later

yes i solved, thanks for the help

So what did you do to resolve the issue, just in case anyone else has the same issue.

yes, it was just a connection problem. I remind everyone that to make the BOB work with the drive, you have to put the negative in common between the two systems

Yes an easy one to make.
