Re: Hacking cartridge HP 84/85

OK, here is my approach. Next to the digital signals, Reset, Clock, and Data (x2), we need a Fire signal which seems to be digital as well. There may also be a Store signal that moves data from the shift register into flipflops, so that the fire signal can be independent of the shift clock. Also, si...

Re: Hacking cartridge HP 84/85

Aw, great :( - I did order a used HP Designjet 90 just because I want to figure out this puzzle. I also got some Teensy controllers. It's not that I don;t have enough to do in my life anyway! :lol:

Re: Hacking the Xaar 128 printhead

I suggest something more fun: publish what you know about those heads here for everyone to read, and I will see what I can do to make schematics and code, which will likely be improved by others on this list, giving you the best starting point possible: peer reviewed code.

Re: Hacking cartridge HP 84/85

@dragonator, you are right. It is just a head with a matching tank. That is promising. I would still highly recommend to use, find, borrow and analogue scope and at least look at each signal once. If they end up all being digital, then that is a nice confirmation. If not, it may save hours and days ...

Re: Oasis 3DP printer

Extruded aluminium Oasis looks great! Very nice. Congratulations! The Iota version you checked out is already a few days old and optimized for colored FDM printing which needs this "overhang" to read the correct colors. This can of course be switched off. Maybe you can send me the STL and I can see ...

Re: Hacking cartridge HP 84/85

I would recommend that you look at all the signals with an analog scope as well why do you think that this can be analog? Because it is unlikely that throw-away cartridges have a processor on them that manages drop size in relation to head temperature and many other little nasty issues with thermal...

Re: Oasis 3DP printer

I have put my color voxel slicer software up into the OpenSource at github. The slicer can generate output from meshes with texture maps for all kinds of 3D printers, including powder/binder machines. Since it is OpenSource, it's easy to add a module that outputs command sequences that the Oasis con...
