Building photon cannon is one of commands for build - probe. You must either give your SCV probe's build ability or edit SCVs build ability and add photon cannon as one of the options. You may also want to remove photon cannons Power User behavior if you want to put it without pylons.
how do i get the SCV to be able to do this?
i have the button on a spot, but photon cannon isnt listed as an ability command for the SCV
