PH-40 base station goes in stand by mode while printing

Hi,
I followed the first steps guide to set up the PH-40 3d printing and got cura to generate correct g-code for the Stepcraft. Little note, the ultimate version of cura doesn't work i had to download an older version and also on page 13 of the guide you can clearly see that the g-code was generated with slic3r wich is a kind of a joke for a guide that is explaining to use cura to not use it.
The problem i'm facing right now is that the base of the head goes in stand-by mode after 5 minutes. From the documentation i found that there is a job active pin in the parallel port but i don't know how to control it.
I'm using UCCNC with the 3d printing plug-in.
Thanks all for the support.
I'm kind dissapointed by the lack of documentation and its quality.
