This DIY flatbed printer uses the new Parallax Propeller chip as the brains, this new microcontroller is very powerful and has many uses.
“First step towards a homemade 3D printer. This is the insides of an HP1360, the paper feed encoder is being used to drive a stepper motor to move the gantry. The encoder is decoded and divided by a parallax propeller microcontroller that also detects the paper feed and ignores other paper feed motor rotations. The gantry is moved by a cable drive to be replaced by a belt.”

I wonder how hard this will be to port to an Amega128 or multiple Mega128’s and have it use a ‘laser cutter’ instead of plotting?

Its not hard, if u got a laser cutter wich is really expensive. Its cool idea to build it ur own because u can develope a plotter a cnc or even a laser cutter as mentioned before. Btw i dont like only-youtube stuff i like if there is some schematic or some picture.

Why port to ATMega’s? The Propeller is a more capable controller with 8 cores instead of 1, and having programmed both, about a thousand times easier.

very cool for homemade. Works better than my Lexmark!

So let me understand this he disassembled an ink jet printer and made an ink jet printer with the parts??? Truly incrediable, man must be a genius!!!

@Joe: Sure ‘all’ he’s done is turned an inkjet printer into a flatbed printer, but even that allows you to do cool stuff like this:
http://techref.massmind.org/techref/pcb/etch/directinkjetresist.htm
(printing etch resist direct onto copper PCBs as an alternative to toner transfer or photo-lithography).
And as he says in the article, this is the first step on his journey to building a 3D printer.

Still think a CNC milling machine would make more reliable circuits. no etch == no broken traces.

Yes if he does more then it might be interesting but as I’ve sure you’ve seen there are thousands of projects with lofty goals and then nothing.

Joe,
As the “genius” who did the conversion I can tell you that it takes more than disassembly and reassembly, try that and you have a printer that destroys itself pretty easily because the same motor that drives the paper also cleans the print head. Sure it’s not rocket science but did anyone say it was.

do you know of any inkjet heads that will print in the vertical positon. i have seen this and the other project at the parallax site. but i need one to go 90 degrees and put a mark on paper. I run an RFID lab and need a cleaner solution than magic markers or air spray gun markers this looks like i would work if i can find the right ink jet cartridge.
can you help.
this is way cool, and you could possibley do posters with it or even larger work.

No specifically but I would not be suprized if most would work like this as long as the were returned to horizontal on a regular basis.

i thought of that, but wonder if i just put the nozzles on the bottom side so most ink runs down. i do not know if pick up tubes are used if they are then i would have to add ink to the reservior to keep it above the tubes to keep it fed.
i may just cut open a cart and find out what is going on.

ok just cut open a lexmark print cart, its just foam, and a pickup hole in the bottom. If i can figure out the pinouts on the cart i should be able to use it. Could also add a permanent reservoir supply above it like an iv, and not worry about the positioning. as the cart would be full at all times.

Who wants to make some $$?? I have a project if anyone is interested. I need to have a flatbed printer built that will print on grains of rice!!! If you can do it I will pay.
