Homebrew PCBs

I like the idea of the flat nozzle, I just run the small perhaps .5in round nozzle around until I
push the print button. OK so now a temp sensor that starts the print on reaching the correct temp.
Oh boy something else to make. I don't know if all the "C" models are the same (seems so) but it
doesn't start printing right away each time. Sometimes there is a big delay before print, other
times its immediate. This means I have to keep the heat on and wait.
