Hi Mark and everyone else that responded.

I am not sure what problem is. Here is the transfer to a bare carrier
https://i.imgur.com/3VkKTgf.jpg and here is the transfer to my copper
board https://imgur.com/ZYg4Po6

I have checked with my meter and there is good continunity between the
plate and the top of the pcb. before I ran it through the printer i
cleaned and gave it quick acetone finish. I am using a toner cartridge
that is near empty, but look how good the finish to the carrier is, it
can't be that can it? I feel like I am so close to getting this
working.

Oh mark this is a hackjob still but
https://github.com/mogorman/e260d_pcbfactory is a working version of
your pseudocode for arduinos. It is what I am using currently as I had
them laying around.
