I like the idea a lot. It would make it useful for everyone trying to make a machine with inkjet, not to mention the possibility of using it for different printheads if they really are that similar.
Sadly I am next to useless when it comes to the printhead, so I am forced to wait you guys to hack a new printhead before I can start on the next printer. I will make a few concept drawings of what I have in mind for the next printer, because I can use feedback on it.
