I think the missing information here is that you are probably using a step-dir servo drive rather than open-loop steppers or servos with LinuxCNC closing the loop. If that is the case, then I am not sure that there is any need to connect the encoders to the PCI card. I _think_ that the G540 firmware for the 5i25 emulates the 8(?) ground pins in a parport, which seems to waste some potentially useful IO. This matters less with a second header for the other 25 pins which I think are GPIO in that config. If the G320(?) has an f-error output then using that achieves much the same result as wiring the encoders back to LinuxCNC. ------------------------------------------------------------------------------ For Developers, A Lot Can Happen In A Second.
