The nozzles were clogged from the solvent ink that I was using. I bought an ultrasonic cleaner yesterday which works miracles. I also ordered some UV curing ink from China to try exactly that. Next week's goal will be to mount the head in an XYZ-axis machine so I can print layers. UV ink s perfect f...

Funny to see how similar our progress is recently. I managed to get patterns printed and also to test all nozzles. Here is a little video:

Amazing work. Great fun to follow. Keeping fingers crossed for all further findings.

That looks absolutely fantastic!

Ink just comes through a 3mm hose from a tank that should sit a few cm below the head. It does not seem to be too critical. But for many inks, the printhead should probably be flushed if not used for a while. White UV ink can not remain in the head for more than 8 hours supposedly! One article claim...

I have not found anything about conductive ink, neither yes or no, but read several times that "only Epson can do that". I am not sure and I have not tried yet. The setup is pretty fragile. I did try solvent based ink and it worked very well. Ordering some UV curable ink for China right no...

Well, since we all have spent so much time on stupid print heads, I have decided to reverse engineer the protocol of an industrial printhead. Sure, it's 200 Euros for a single head in a single color at only 200 dpi, but these babies are industrial strength, giving them supposedly a much longer life ...

Not bad for Python in general

No, seriously, great job. Did you make roll own electronics? Or is this with some included interface?

I use these to drive a 6x6 matrix, but using SPI may be a bit slow for a printhead:
