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 volt charge and then it works until the
limit switch is closed.
I could just remove the limit switch. But it still needs to have that 5V
initially.
I was thinking there might be a way to make pin 13 an output pin.
'Not sure what to do here.

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
http://linuxcnc.org/docs/2.2/html/hal_drivers.html#fig:Parport-block-diag) EMC
cannot set this pin to HIGH or LOW.
