Hello, do you think there would be a problem with long-term use (for example, when working for 1 hour) such as burning nozzles? I'm thinking of making a binder jet printer. Would it make more sense to make a circuit that will cut the voltage after each layer?
Me: If you would have read this chapter in full, or at least what is written at figure 6 and had a look at the circuit in figure 9 you would have noticed that eaxh nozzle is only powered for 3μs and then paused for at least 0.5μs. That means the voltage IS CUT OFF! How do you wwnt to implement a "cut-off-what already-is-cut-off" circuit? ;-)
In my world printer project, the print head was running 24/7 and did not end up in magic blue smoke. Just make sure there are no software bugs in terms of timing when you start to modify my source code.

Hi again! I installed Ubuntu and now its okay with Arduino board. The codes start working but there is no spraying. I checked the 18v point of the HP6602A head and it works fine. Where else should I check to make sure the diagram works?

Me: ...and again you think I would own a crystal ball, but I still don't!
Something is wrong with your circuit and without having photos of your board I can't say where the problem is.

Sorry about that.. I am using virtualbox for Ubuntu.
ubuntu 64bit installed. I think the software cannot find the com port, virtualbox sees arduino, but when I run it, I get this error.
Me: I can't say anything about virtual box (never used that). Yes, the commandline tool obviously can't find the USB port. You can try changing that in the source code (Line 28 / 29).
...or install Ubuntu directly on your disc.

Hello, I am getting an error like this
Waiting for 'X' from Arduino (Arduino pluged in?)
Me: Your Computer (version), your operating system (version)?
What makes you think that I would own a crystal ball?

Hi! I tried inkshield before and couldn't reach a conclusion. Your project seems to be much simplified. I want to ask is that I have the arduino mega 2560, can I use it instead of Arduino uno?
Me: That should work with your MEGA 2560.

I would like to join the Patreon site because I am very interested in this project.
How do you send it a BMP file and then get it to print it?
Me: As written on this page, the Software handling 24Bit *.bmp files is available as download. Details on how to compile the source code are in the readme_en.txt of the package. Of course, you need some coding skills to understand how it works. Without that, you can still install the software and make it work, but you won't be able to do more than my code offers. It is an easy task to write software with great capabilities, but it is an endless process to make that software work with coding-Muggles ;-)
More on Physical Computing will follow, soon.

Thank you for replying so fast!
I was able to order the awesome adapter that you linked. I will have to wait a couple weeks for the male FPC cable to arrive.
In your description, you mention a female FPC to DIP adapter, I think? "For further tests, I bought suitable sockets in which the pins are led outwards at a greater distance."
I'm interested in this socket! FPC cables vary in pitch width, number of conductors, etc. A specific socket is needed, and I don't have the cable here to measure
Me: Yes, that information was missing, I have added that to figure 5.
The pitch on the cable side is 1mm and a total of 16 pins is needed.
Thanks for pointing that out.

Hello! Big fan of yours.
You mentioned that you used an FPC breakout adapter?
Can you please provide the model number or link to digikey to mouser for that?
Thanks
Nick
Me: Why? Are you too lazy to search for such an adapter by yourself in the shops you prefer?
I guess you mean the print head mount? In the table at the bottom of the page I have set a link to arrayink which is the only shop I have found to offer that part.

Hi Norbert,
interessantes Projekt - habe mich kürzlich wieder sehr über ein Produkt aus dem Hause HP geärgert...
Eine Frage: nutzt du noch die Elektronik des 3D-Druckers, oder treibst du die Stepper direkt über dein Board?
Gruß,
Andreas
Me: Es geht einfach nix über Open Source Hard- und Software!
Die Elektronik des Druckers ist entsorgt. Ich hatte keine Lust, mich mit dem Reverse Engineering der Firmware rumzuärgern. Läuft alles über den Arduino UNO.

I'm not good with Arduino & don't want to waste my time on it, but I really like what you have done with this project. Have you ever seen it anywhere in your research for PIC micro controllers preferably in XC8? Unfortunately I don't have time to do manual conversion :( Any help would be awesome.
Me: Sorry, the Arduino control sketch is the only software I can offer. It isn't a big sketch, should be no big deal to convert it into something else.

Hallo HomeFaciens,
man könnt erstmal mit Original-Tinte einen probe Druck machen und Testweise Ätzen. Ist es möglich das Sie eine Platine bedrucken und mir zu kommen lassen. Das ergebnis vom Ätzen würde ich dann in Bilder zu kommen lassen. Eine Spende für die Unkosten sollte kein problem sein.
Me: Da muss ich den Drucker erst mal wieder in Betrieb nehmen...
Lass mal ne kleine Datei rüberwachsen, dann probier ich die mal zu drucken, wenn ich Zeit dazu finde.

Hallo HomeFaciens,
ein sehr schönes Projekt, mich würde Interessieren ob sich mit diesem verfahren Platinen bedrucken lassen. Für Prototypen wäre das perfekt vor allem bei SMD mit den kleinen abständen, voraus gesetzt das die Tinte das Ätzbad überlebt.
Vielen Dank
Me: Da ich mich mit Platinen-Ätzen noch nicht beschäftigt habe, kann ich dazu leider keine Aussage machen. Da die Druckköpfe relativ robust sind, könnte man zumindest mit underschiedlichen (pigmentierten) Tinten experimentieren. Dazu muss die Patrone aber geöffnet, und der Schwamm im Innern getauscht bzw. ausgewaschen werden.

Hi HomoFaciens,
Did you happen to document the corresponding pin terminals on the print head to the FPC cable? From the diagram it looks like the start and end are Vcc. Does there need to be a certain order of the pins 1-12?
Thanks, keep on hacking!
Me: You obviously found figure number 9 that shows that Vcc is on the outermost pins of the cable. If you now also have a look at figure number 8, you'll find what pin of the cable belongs to what nozzle. Of course you can swap that mapping if you'd like to since all nozzles are identically and also all outputs of the driver ICs.

Where can I get to know more about the working of this project in detail. I need to know as I am also working on a similar project. I really need to interact with you. How can I contact you?
Me: Same as on almost all Internet pages, I have also created a column named contact for my project.

Sir if i try to implement a similar project, can i use any other printhead other than HP6602 which i can control using arduino or any other good suggestion from you where i can change both printhead and also the controller. Thank You
Me: The only documentation I have found is for the HP 6602 and the HP 45 cartridges.

You mentioned that you wanted to do this on a cylinder. Have you figured out a way to implement this on circular geometric objects?
Me: If it is a cylinder, all you have to do is mounting the motor for paper feed on the cylinder axis. There is no need for any coordinate transformation.

Can you build a circuit that can run 128 epson xp600 heads at the same time?
Me: The hard thing will be to figure out the electric characteristics of that print head since there is usually no documentation available.
