I just got a P600 from BH photo in NY (delivering this week) for $430 after the rebate. free shipping and the best price I could find - it was that price until 12/31/15 then it went up. I am getting my T-dozer kit today and would love to talk to anyone who has built or is building one too. I have lots of mechanical experience, I am a machinist and jeweler - so the technical aspects .are of no real concern, but the computer side of things are a little more difficult - sure I can figure it out but would love to have folks to talk to throughout this process.That's a great price Skip
1.) I posted pics and description on the builders group of how i make my spit tray, there are many ways but it will give you reference.
2.) I would consult with the folks who sell the bulk ink carts systems for your best options, i would start out with refill carts until your familar with how everything works.
3.) Waste ink, any waste bottle or bag will work, its normally set on the side of the base " lower than the printer" It will eject waste ink slightly up gravity but best is lower than the printer.
4.)Always want to flush the system from OEM inks, you will need a set of flushing carts same as regular carts only cleaning solution. you want to get the adjustment program for the P-600 it has an ink charge feature that can be used for charging flushing/ It also has 3 levels of cleaning that can be used for the same. Ink charges require the carts to show completely full after the first use they will never be all full at once again so at that point the 3 different levels of cleaning can be used. adjustment program link was put on the builders group.
5.) I would email the site direct for any updates on the Platen, we are at the mercy of the manufacturer on those. Best wishes
