This I've got to SEE!
i guess i'll start a progress report here and there. of course posting pics at this point is premature. here's the pics of the table (it's kind of hard to get a sense of scale). ...the linear guides, i also have a pair of ball screws (250lb each) that i will invert.
first step is to mount the printer to a trolly. i don't want to mount directly to the gantry because i want this table to be multipurpose. so it will be more of a pusher.
in a while i'll post some pics of the printer tear down (first doing ink/coating tests with it) after that i'll start with mounting it to the table.
Very interesting project, i will be sure to follow your progress.. I spent alot of time on r&d on our recent printer project which is a small format and i have been prototyping small formats for just over two years.. I cant imagine the time and r&d required going in blind... It will be something to see for sure.. seems like a very unique printing niche you havei'll just run 60" wide to begin with. ...will upgrade to an 87" wide printer later. maybe a dual dx5 wit-color ultra 9000 2.2m or a konica 512 42pl of some sort. the choices in the 2.2 meter range aren't that great. but they're out there. i have separate heating systems and transportation, racks, and rotisserie tables all built to the 80" x 120" dim. you can get sintra and poly carb that wide.
the rest of the table can be used for staging and run at both ends of the print (the oce 550gt works this way) and or when doing ceramic tile projects, i'll be able to lay out the entire project, make several passes before it goes in the kiln.
the table has all the motors (two big servos) and livear drive already on both sides. looks like a 20mm rail with gear track under the table, big chunky belts.
one thing i'm needing to do is get the encad's x-axis signal which usually goes to the servo on the printer to be run through a servo controller then split between the two servos on the gantry. not sure if i'll need to leave the encad's servo "installed" as a proxy in case the firmware throws an error because of it's absence, or if the signal being hacked will cause some drain on the main board. i have no idea how to do the electronic side. i figure i'll just have to get there first.
Some very interesting projects.. you seem to have the experience behind the printers your working with so this should go smooth for ya.. I will have a new toy to show not to far in the future aswell Cant wait to see your creation.. I love this stuffalso, here's a link to a colleague of mine that recently finished his mutoh pinch roller flatbed with z-up gantry.

Swamp cooler? you can dump some serious $ prototyping for sure.. I would hate to add up what i have in this total I have built alot of stuff but for some reason the printers have hypnotized me..lol I think its the challenge and then other challenges present themselves or maybe its the utter pursuit of design perfection? you know what im saying wake up at 2am with a thought and run to the basement with your micrometer whatever it is its fun.. I look forward to reading about your project as its developed..one catch is all my equipment is loaded into my house (long story). i have 3 acres with 3phase power on my street, yet, i wake up to equipment everywhere. the printer build is going to be done in a large tent (hansen weatherport) behind my house. so while doing meticulous mods and busting knuckles, i'll be swatting mosquitoes in 100% humidity (texas near the coast). also, along with the build i have to deal with geckos and mud daubers building a home in the nether parts as well. the budget for the whole thing is around $10,000. i stole the table for $3k on ebay. shipping and rigging cost almost as much. so i've got about $4-5k left for machining parts, electricians, servo controller, vac pump, massive data chain, replacing the lasered to death aluminum top.
