Re: Hacking cartridge HP 84/85

How reliable are the latest drafts on this really nice printhead? Are the voltages correct? I saw some of the timings, but what are the chance of them working? I hate to see MAsic12345 struggle on the software side after he did such nice research on the hardware side, but it is so difficult to help ...

Re: Hacking cartridge HP 84/85

The teensy 4.0 was released a few weeks ago. It is faster by a factor factor of 100 over the 3.2. Not sure if that is true for all operations, especially DMA, which seems to be the solution here.

Re: Hacking the Xaar 128 printhead

Teensy have enough pins. If you need more, Arduino Due are an option (ARM CPU). Xaar heads use a serial protocol and can be daisy-chained. If you can be fast enough, you can control as many heads as you wish with the same control pins.

Re: Hacking the Xaar 128 printhead

I have only tried solvent based ink, yes. Tritron V Photon black is a suggestion from the Xaar ink recommendation list specifically for the 128, but who knows if that list is correct. This is the only UV ink mentioned there. Water based ink fails for me completely. It took me forever to find that ou...

Re: Hacking the Xaar 128 printhead

I think Tritron V Photon black ink is UV ink that is recommended by Xaar for the 128. Not sure though.

Re: color 3dp slicer software

I wrote a slicer that can do just that. It is by no means finished, and the current version has the texture stuff disabled because I was trying to control a mixing FDM printer first, and then finish the texture stuff. If you are really interested and have a printer that would work with this, I can s...
