Actually I do have it on a 5V breakout board but it is still putting out 2.44
volts on pin 13.
Someone gave me a tip that worked. I just inserted a 4.7 pullup resistor and
now things are running smooth.
Thanks for the input.

Hi Mark
I suspect that this is a 3 volt parport. One recommended procedure is
to use a powered breakout board. You could also use a PCI parport card
that produces a 5 volt signal.

Thanks for the link.
Yeah that's right. Pin 13 is input. It is used for the z limit switch.
For some reason the pin is showing 2.44 volts.
The controller needs to see 5 volts to tell it things are a go.
At 2.44 volts the z motor won't do anything.
I have tried momentarily giving it a 5 vol
You can make an output pin HIGH all the time by using "setp" in your hal
file:
setp parport.0.pin-MM-out 1
^^ replace MM with the pin number
However, parport pin 13 is an input to the PC, not an output (see

Hi,
'Just trying to get on board here and I don't know much yet.
I am running a controller board that needs to have pin 13 set high on the
parallel port to enable the Z-axis. Otherwise it thinks the limit switch is
open.
Can someone tell me how I can do this?
Thanks, MJ
