Re: Interest in a Open Source Printer Kit?
- Here's a new simple video showing the test ink ejection:
Once I receive the boards back, I can show some actual graphics
printing (solder wires to the legs of the 1mm ffc is a pain).
I use a 4.5us pulse and a 1ms delay between ejections. You can see
it's almost a constant stream out of 1 nozzle. My code is written for
the parallax propeller and will be able soon when I have had time to
clean it up.
The circuit can be built on a breadboard and I think is perfect for
experimenters. Not only are the higher resolution heads more of a
pain to drive since they don't have any documentation but you also
need to stream a lot of data. 600x600 dpi x4 colors = 1.44mbps per
square inch you want to cover. While 96x96dpix1 color=~9.2kbps.
With the propeller chip, there are modules for high speed streaming
which makes tinkering a lot easier. Using viewport, you can stream
data at 2mbps over usb from say Matlab into a buffer which holds your
image file and does the processing.
When it runs out of ink, I'll drill and tap a hole for a barb fitting
to test a CIS system.
If you don't want the X axis assembly, I can get you the head holder +
FFC connector for $60 and you can build your own mounting, pcb, etc.
If you mount this on the CNC you will have a printer capable of all
sorts of cool things.

I haven't protected the folder already, should I?
The rar (rar is much slower to brute force) has this password: diy_3dp&f
And for me should be enough.
Tell me if you want me to close the folder and what to use for user-pass. I can do that this evening.
