Will you add a built-in planned obsolescence too ?

[smitp]

Thank you so much for solving my doubt of HP 6602 pin configuration and adding an image on your web page, you solved my biggest doubt and you made my day a lot ....god bless you ...stay fit and always make this type of creative a lot

I suggest soldering solenoid wire to the connector. It's easier, more robust, and less messy. Great project, as always!

This is what I need, with this technology I can print an easy supports separation layer when 3d printing. You earn sub.

This is some exciting work. I was thinking to do something like this or copying your dot matrix printer but using acupuncture needles for finer resolution for large format printing.

Thank so much for sharing 👍 the type of projects you implement are very useful for thinkers and inventors. I wonder if we can make a print head from scratch thus we can use regular ink, or even a homemade ink for some special project, please keep the good work coming, thank you

[ericlotze]

I love how you do a version in both languages!

[noweare]

This was an awesome project. You do really cool stuff.

[ecan]

Hats off!! Very nice video and many thanks for for sharing your work! It will be very useful as a start point to hopefully develop some ideas I have in mind :)

Free inkjet printing is on the way. Good job! Keep it Up!

[pesho]

Omg this is the biggest coincidence.I was looking into driving a c6602a cartridge a few days ago

[TechBuild]

Why does the printhead spray ink only when the head is moving to the right? Why not make it spray the intermediate lines when going to left as well? It can help speed up the printing process.

[memejeff]

Thank you. Very useful and interesting.

Nice! Best regards from Chihuahua México. 🙋

The world needs an open source inkjet printer, wich is easily repairable and can be refilled with ink. This would force big companies to sell reliable printers, and cheap ink.

@
HomoFaciens Have you seen the "InkShield" ? It's an Open Source Arduino Shield for Projects like this.

[elektronstorm]

Cool project, could you turn it into the color MJF printer perhaps?

[silber]

And thoughts about using such a print head to print using conductive ink?

[abcmeins]

Could you make a colored 3D print with this? I mean when you print a layer of the 3D print. Then use the inc-jet head to print color on the outer shells. Then print the next layer and so on. Of course you would have to add a CMY-head as well, but this could lead to relatively cheap easy to produce full color 3D printers. You could even just add on the printheads to existing printers!

Cool.
I have made a display case for a touch scree to learn LinuxCNC program.
