I just looked up the i9900, but that looks like a glorious printer. I can’t wait to see more details about what you are going to so with it. I am quite curious about the maintenance bay. If there ever comes a better 3DP printer, it is a component that needs to be duplicated. What is all on there.
Good luck with the hacking and while it might be a bit of a pain to upload, please share photo’s if you can.
