hello
i use a laptop(with pci express slot)for my cnc but i don't know why lpt port doesn't work
its my device manager info:

thanx

i tried 4ff8 and 4ff0 but they don't work too

First off Laptops may be problematic so they are not officially supported.
What operating system are you using? Is it 32 or 64bit?

I didn't see the Mach3 driver listed in the devices.

i use win7 64x

I didn't see the Mach3 driver listed in the devices.

and what is that?

and thank you for your help

i use win7 64x

That is why it wont work, Mach parallel port driver will not work with 64Bit OS's, only 32bit. If you want to use Mach with a 64Bit OS then you will need to use one of the external controllers (PoKeys, SmoothStepper, CSMIO, DSPMC etc etc)

It is the Mach parallel port driver but as explained above it wont install for you and that is why I asked what OS you had
Hood

it means if i use xp 32bit it will work

No guarantees it will work as it seems there are just some parallel port cards that wont but using a 32bit OS will allow the Mach driver to install so chances are it will work.

thank you
and an other question
which i/o range i must chose ?

4FF8 would be it.
